i filled my box up b4 i left va and buy the time my light came on it 282 miles to the tank, thats pretty poor i think.

thats about what i get but i'm mostly city driving

If the light comes on with a gallon left in the tank, then you got 31mpg(282/9).

I normally do not let my tank get that low, but I have caclulating by taking miles/number of gallons purchased to get tank full. When doing this am averaging 33 to the gallon

Yea that is about what I get. I am half way through my gas and I am at 150miles. For some reason I expected it to be more since my Saturn gets the same mileage and I thought my Saturn sucked but I guess I never did the math.

If the light came on with 2 gallons left ( a number I have seens discussed here) that would be 28.5 mpg. If it came on with 1.5 gallons that would be 27.1 mpg. If it came on with 2.5 gallons left that would be 30 mpg.
Maybe.
The lights are not calibrated and would vary from car to car.

I assume you were driving all highway? If not then that's OK mileage. If it is then there are a few more questions.
Are you sure you really got it filled up? Gas pumps vary greatly at where they kick off. Sometimes you really have to work to get it filled with a sensitive pump.
Did you use cruise control? If you have one it can greatly improve your mileage.
How fast did you drive most of the time?
Is your xB modded? What wheels and tires do you have? Larger or smaller diameter tires can affect multiple variables.

I think it would be very helpful if gas mileage discussions used the same "factors". It would provide more accurate information and allow others to use the information to consider their own factors.

To that end I would suggest people try to provide more information and use a consistent approach to calculating and reporting gas mileage. I've already seen one guys go off and buy an Element because he was convinced there was not much difference in mileage. :lol:

First and most important point:
Fill the tank with the car as close to level as possible.
Drive.
Fill the car again with it level. (Be careful to get it fill the same way both times.)
Divide the miles shown on the odometer by the number of gallons shown on the pump. This is the only way to get a reasonably accurate mileage number.

Second list the factors:
Was this city driving, highway or a combination?
Did you use a cruise control?
If you were driving on the highway about what speed did you usually drive?
How would you describe your driving style?
- I take it easy mostly
- I drive hard sometimes
- My carpet is wearing out under my gas pedal
What were the road conditions? Anything unusual like driving in the mountains?
Do you have stock tires and wheels? If not what do you have?
Do you have any other mods that could affect your mileage?

If something like this could be followed it might help reduce some of the concerns about the mileage. Of course it could go the other way too......
Nevermind. :lol:
:wink:

that's about what i get on a tank with city & hwy driving. if that was all hwy driving that isn't that great.

my light came on last night, and i had out 204 miles on it since my last fill up, and I can put between 9.5-10 galllons of gas in my car right after the light comes on. so i gues im getting roughly 20 mpg?

I dont wait til the light comes on. I usually fill up at the last quarter. Ranges around 190ish-200ish.

I pulled 330 once when I drove like a grandpa. Mostly 280-300. Driving 65 just seems sooooooooooo slow.

I log my mileage at every fill-up and average 33MPG on mostly highway driving at 65-75MPH. Last night's fillup at 336 miles was the most miles I've had at a fill-up. I think it was 10.33 gallons.

I keep my log in the back of that "Getting Started" Scion manual. There's a few lined pages for notes. I log date, gallons, price, miles and then calculate the mileage. You have to make sure you reset the trip odometer at each fill up so you're using the actually milage when calculating. Get the exact amount of gallons from the receipt. It's the only way to ensure accuracy.

I avg about 33 mpg..no matter what I do

Hey.. first time posting.. been lurking long enough.

Been getting between 30-37 MPG, average 33. The 37 was during the break-in period all on the Thruway. I think the break-in is a pain for 1500 miles if you speed, but is worth it.. especially for the looks in traffic.

pileofmonkeycrap's got a point, but try this. use the same gas station to fill up with and just until it clicks, no further, no topping off, etc. Reset trip, drive, fill until it clicks, calculate (with the 5% odo discrepancy).

it was highway, 60 the entire way, i dont usually wait till the light comes on but i wanted to see if i was gettin the claimed 35 mpg, maybe when i change to synthetic oil

it was highway, 60 the entire way, i dont usually wait till the light comes on but i wanted to see if i was gettin the claimed 35 mpg, maybe when i change to synthetic oil
Try one of the more accurate measurments suggested in my long rambling mess or maybe pileofmonkeycrap's or Scionic Librarian's shorter suggestions.
If you then find you are getting something like 25-30 under your described conditions maybe there is in fact something wrong with your car. :(
If your estimate is very close you are clearly getting significantly less than most others in those driving conditions.

Dudes I got 320 miles on 9.5 gallons of gas my last road trip
I filled up the BOX drove then filled up after I dropped the kids off
9.502 gallons for the re-fill Do the math 33.67 miles per gallon!!!
I was totally impressed, and average Interstate speed was 85 miles per hour

I am still getting, on average, around 36 MPG. Of course, I drive in SOUTH FLORIDA, with little to no hills. And I drive 'like grandpa', most of the time. Mostly drive in the city, between 35 and 40 MPH, and in the thirties, I have it in 4th gear, in the 40's and above, mostly in fifth.

I think that weight (as in what you got in the Box), makes a big deal towards your mileage as well.

You know, even if I was getting like 33, I would still be getting better then most SUVs on the road, and better mileage then my nBeetle gets. So I would not complain too much.

Estimating how much of a tank you used is useless. You've got to keep track of the ACTUAL miles driven and the ACTUAL amount of gas you put into it. For a true reflection, you need to find the average over several tanks of gas.

I think anything over 250 is GREAT i cant get anything higher and i have an intake and exhaust which is suppose to help and improve gas mileage

Most of the time, MOF, I use the 'mid grade' of gas. Costs more, but it burns cleaner, and I think helps with the mileage.

Yup.
There's two more "factors" to be considered that make logical additions to my earlier list. Any of those can make some difference and TheScionicMan is very correct. Several samples will make sure you did not have something weird happen.

Quick short story to that effect:
The guys where I work tell about a guy there buying a new Dodge Omni back in the late 70's (I think that's the time). He bragged about the mileage he was going to get with this car before he even got it.
From the first day he drove it to work these guys were adding a little gas to his tank every day. He was going on and on about how he was getting over 40 miles per gallon!
Then after about a month of this, they started siphoning out a little every day. He was soon at the dealer complaining that his mileage dropped from 40+ to about 10 mpg.
:lol: :lol: :lol:

The moral of the story is: If you are getting extremely different gas mileage than you expect don't rule out foul play. :twisted:

No not you, your post wasn't even there when i started typing. it was regarding the first thread...

It's like saying Geez, that took forever... without checking the time before and after...

I think that weight (as in what you got in the Box), makes a big deal towards your mileage as well.


Are you calling me fat? thanks dude.

...and average Interstate speed was 85 miles per hour

That number is suspect unless you happen to be a cop in Texas or Montana. :)

Many people think that they maintain such high averages, but if they use a GPS or simply divide total distance by total time they'll likely find that their number is considerably less. We tend to remember the time we're driving 85 but forget the time that we're slowed to 55 or 60.

when the light comes on theres still like 2 plus gallons left in the tank. thats why i can never put more than 10 gallons in
normally less than that. but if yer gettin that small amount of mileage only goin 60 on the freeway man somethiun is wrong . either that or you have 19's and full beat and dynamat and such.

I think that weight (as in what you got in the Box), makes a big deal towards your mileage as well.


Are you calling me fat? thanks dude.No, not calling you fat. But some dudes put lots of weight in the back with subs and such. Thus, the gas mileage goes down.

My light comes on at around 290 miles, and I have been getting anywhere from 27 MPG (once) to 33 MPG (several times). Overall I am quite pleased with the MPG of the XB :)

Was that before or after the 5% add-on for odometer discrep?

If someone can find that thread, that could account for why some peeps are going a lil nuts with low gas mileage. Not that it'll make much of a difference, but that .04 MPG could brighten someone's day... somewhere... over the rainbow... :lol:

I've been extremely let down by my Scions range personally. 3 tanks in a row now and my range has only been 250-260. That's driving to the light and then 20-25 miles beyond.

I don't know about you guys but I bought this car for the 32-35 it said on the tag, not 25... My old pile celica GT had a range of 350-370... 320 minimum and that was all city driving. The tank on it is only 1 gallon larger and it's definitely heavier.

Truthfully, I'm pretty let down right now. I bought this car for that purpose and that purpose only. Gas milage. Isn't there some recourse on Scion itself if they misrepresented some numbers?

Oh and btw, for general clarification, I drove this last tank so slow it made me mad. I was accelerating slow enough to where the guy behind me would always be right on my tail. Slow enough to ____ people off and make them scream around me. I never exceeded 70 once.

Something isn't right. Driving like that should yield an easy 300 range. From what I understand, it's an 11.9 gallon tank... 30mpg by SIMPLE calculations should yield a 300 mile range by the time the light hits. I'd be content with that.

Someone tell me I'm wrong.

Sometimes the ride feels rough and sometimes smooth.
Stupid question, but does different gas stations have a difference? Example: 7evelen, Mobile...

I found that short trips and starting the car more than a dozen times on a tank seems to cut into my milage. During the weekdays I commute 54 miles each way equally along rolling country roads and superhighway with several occasions a day of flooring it to either pass people on the 2 lane road or making my death defying left turn onto the very busy US 15 while trying to avoid getting killed. I average 33-35 mpg driving between 60-80mph but on the weekends with all the shopping trips, I've managed to drag it down to 28-30 mpg @ 40-50mph.

On long road trips where I'll only stop maybe once in 300 miles, I'll see 35-39mpg. I do my best to avoid roads with the stop and go inaction especially with a clutch. I also shift earlier than the recommendations if the conditions and terrain allow me to. i.e. I will be in 5th by 40 MPH while skipping 4th.

Sometimes the ride feels rough and sometimes smooth.
Stupid question, but does different gas stations have a difference? Example: 7evelen, Mobile...

Smoothness of the road does affect milage. The brand of gas is more a religious argument but in my case I found that using any grade above 87 does nothing for my milage or performance. I burn Wawa 87 octane but will occasionally put a couple of tanks of BP/Amoco in to clean out the injectors. (I've never failed an emmisions test with Amoco(BP) super even with a hollow cat on my old Econoline) :wink:

One question. I am curious if that rear fin is a factor? I have observed that many people who buy these boxes for economy have the basic model.

HMMMM. Something seems amiss here. Your mileage seems much lower than most others' here. I've found that new car dealers are notorious for not bothering to check tire pressure when they "prep"a car for delivery. Make sure your tire pressure is somewhere between Scion specs and the max on the tire sidewall. One low tire could wreck your gas mileage.

Mark

I usually go at least 250 miles at the 1/4 tank mark. And that's usually doing 75-80 mph on I-5 to SoCal.

Other contributing factors are head wind, wheel and tire size, tire pressure, passengers, cargo, and sometimes outside condition of car. If your car is dirty and hasn't been waxed, even minute, could have an effect on mileage.

Just a few things to think of.

30.5 today. I drive 5spd about 7/45 minutes on street the rest on highway twice every day (about 1.2 miles on streets and 45 on highway). I'm not happy with it, but it's within the est that the sticker said. BUT, I've noticed that the car smells and acts as though it's running real rich. I can really smell unburned gas when it's warming up and it never seems to loose the "choke half on" feel some days.. hmmm.

I drive through DC every day, so 99% of my driving is stop and go, and I usually shift at around 3500-4000 rpm. On the highway, I drive around 60-70 mph.

My car has the stock wheels. I have one 10" sub. I average 32 MPG.

just so everyone knows there is at least 1-2 gallons left when the light comes on. and another thing the light doesnt always come on at thesame time. sometimes at 1/8th tank other times at about a 1/4 so dont go by "when the light comes on" at certain times i've gone like 75 miles after the light came on. so..... just a lil sumptin for you all to checw on. if u wanna calculate mileage do a complete fill-up and then drive till only half or only 1/4 is left don't use the light as a gauge. it is a pos.

I've been extremely let down by my Scions range personally. 3 tanks in a row now and my range has only been 250-260.

One problem with the Scion's range is that it inherited the Echo's tiny gas tank. Unfortunately, it also has a higher (numerically) axle ratio, more drag and therefore gets less mileage. The combination yields range that is about 100 miles less than most American drivers are used to.

I wish that some of the folks making stupid bling-bling and carbon fiber junk would realize that there might be money in marketing a functional 15 gallon replacement gas tank.

George

The weather affect the mileage also. My milege drop by about 1 MPG this week compared to last week. It has been freezing lately. Up to last month, My mileage ranges from 31 to 35 MPG. Now it ranges from 30.5 to 32.5 MPG.

that tank would be a very expensive mod.

Might help to read this:
http://www.fueleconomy.gov/feg/why_differ.shtml

I'm getting 33 on my Xb (auto), for mixed driving (city/freeway). Kinda disappointed, cuz I used to get about same mileage with Celica GTS (6-speed). I thought I would get alot more mileage since it's smaller engine, but guess the weight, and the shape of the car hurts the mileage ... hmm .... Maybe I should have went with manual ...
BTW, I measure my mileage by filling up to full, at same gas station, and reset my odometer each time I fill ...

auto's get better mileage. it's in their final drive gearing identical boxes at 70mph will produce like 3500 rpm in a manual and like 3200 or so in an auto. in these cars manual is for fun and auto is for economy.

Truthfully, I'm pretty let down right now. I bought this car for that purpose and that purpose only. Gas milage. Isn't there some recourse on Scion itself if they misrepresented some numbers?


They are strictly an EPA ESTIMATE to allow people to compare differnt car makes and types.

Fuel economy is measured under controlled conditions in a laboratory using a standardized test procedure specified by federal law. Manufacturers test their own vehicles—usually pre-production prototypes—and report the results to EPA. EPA reviews the results and confirms about 10-15 percent of them through their own tests at the National Vehicles and Fuel Emissions Laboratory.

The numbers don't represent real driving nor do they even calculate the amount of gas used/miles driven. It is a simulated test done on a treadmill, with some fluctuations in speed, but in reality represent an average speed of about 48 MPH, IIRC. For every 10 MPH over that you go, there is an exponential loss from those numbers...

the highway numbers are done at 60 i believe either way not a very accurate way of measuring.

that tank would be a very expensive mod.

Very expensive? A bolt-in replacement oversized 14 gallon tank for a VW bug is $72!

http://www.doghouserepair.com/mall/description.php?ItemID=2471

(and the shape of this one is a lot more complicated than the Scion's!)

The problem isn't the price, it's the market. The people buying xBs would rather buy a carbon fiber fuel door than something that actually improves the vehicle but doesn't show on the outside.

And not sold in the US for the last 25 years!

I see more Scions on the street than aircooled VWs, even though I live in one of the prime areas for aircooled VW fanatics. The bug that this tank fits hasn't been sold here for over 25 years, yet there is still a big enough market for the oversize tanks for someone to tool up.

It's a pity that Scion owners can't create that same demand. Perhaps if the tank came in carbon fiber with built-in neon lights...

George.

I'm getting around 28 to 30 and I fly downt eh interstate every night going to and from work. usualy 70 to 100 mph. lol I still think i onw a sports car i geuss ha ha

nice a cf tank with neons ohhh ahhh

got 347 miles out of one tank. I did not look to see how many gallons I put on my tank. I was really impressed. The firt two tanks I reall grandma drove my box. and got only 312. This time I wipped my hampster a few times and got better milage. Go figure. I really have to pay attention to what I put in my box.

Go little hampsters Go!

Someone up there mentioned maybe the 'wing' might help with the mileage, so I went back to my little gas book...and yes, the book tells me that when I first got the Box, with out the wing, the mileage was less. With the wing, it got better. Now, that was further in, as in, further in on the break in time. So, that might have also helped with the MPG.

And, I think that some one menttioned the temp, as in outside temp having something to do with the MPG. I seem to recall that in winter up north, this was true. That was a long time ago, so I may be wrong.

I just filled up my 5 speed XB for the first time. 9.89 gal., 319.2 miles. 32.27 MPG. I shift at 3,500-4,000 RPM, and this is combo highway, city driving. This is also an empty box.

I purchased a airsensor chip mod for my 2005 Scion xB for $8.00 Including shipping and installed it and my miles per gallon skyrocketed! I dont know what it is but I go a week or more on a full tank when befor I filled twice a week. I would recomend this resistor chip, its cheap, it safe, it adds 14-20 horsepower and U get better gas milage. My theory is that the xB is heavy for that small engine and our stock engines and sensores don't let enough oxegen and gas into the engine to push it up to a satisfactory speed with a low rpm. so this modification increases intake = horsepower without shooting up rpms burning more gas per second. i purchased this item from ebay it came with simple instrucionas and its simple to install! Please ask me any questions.

im pullin almost 400 to the tank... i cut it close to 380s... when my tank is at half im at 200 miles.. i went from Gloucester VA on a full tank and drove all the way to Bristol TN with just a lil above an empty tank... had enough to look for gas station thats a 540mile trip... i love my box

Any tech guys/gals have an opinion on the airsensor chip mentioned above? I've heard this on a commercial.. but wondering if it's legit..

Yoy guys are a F-ING riot :D
Man i have about 4,000 miles and the best mpg's i got was 29.4 miles.......
That is filling it with 9.4 gallons of 87 oct.
Hey man i was hella happy with that, got that right after i through on gabes axal back 8) i definatley recremend his exaust, before that i was geting 26-27 on a average...
Also what kind of gas are you guys using...ive been filling up with ampm

Any tech guys/gals have an opinion on the airsensor chip mentioned above? I've heard this on a commercial.. but wondering if it's legit..

Do you honestly think some guy on eBay figured out something that is UNIVERSAL to all cars yet the car makers with their millions in R&D couldn't do with their OWN engines? And even if Professor eBay did find this miracle cure, why wouldn't the car makers just add it for $8 bucks and gain all this HP that is very important to some carshoppers?

C'mon, use your common sense, do you really think you'll gain 15-20 horse power and at the same time use LESS gas? From a generic resistor that's going to outsmart the very intricate ECU?

Look at it another way, what if your engine chunks after using it for a month because the air/fuel ratio has been altered. What's their guarantee? Oh yeah, they'll give you your $8 back. You can just hand it over to your dealer with the rest out of your pocket...

JMO, but think about it...

the dealer would fix it as long as he didnt cut the wires to add the resistor. but yeah i havent noticed anything with that junk but oh well.

You guys realise that when you lower the car it upsets the calibration of your gas meter? (When you lower the car more in the front and less in the rear, Tein does this) The level of the gas leans in the tank, and depending where the float in the tank is it could read the wrong level of gas. My moms '02 Honda Odyssey did this, It would light up way too soon when the car had only one or two people in it. They calibrated it expectiong a load to be in the car, when there wasn't a load in the car the light came on way too soon. Maybe this happens in the Scions after we lower them?

But you shouldn't use your gas gauge as a way to calculate MPG, it needs to be based on miles driven and gas used not when does the light come on...

yeah easiest way it from full to half or full to 1/4

I drive 80mph on the hwy and a good deal of city. I still avg 300 miles plus to a tank.

I have gas right now...wait. We are not talking about that kind of gas.

Sorry.

Theoretically a lowered box should get better milage because less air would travel beneath the vehicle and all of those unsmooth surfaces and adding drag. :roll:

You know the longer this discussion goes the more I'm beginning to remember and get ticked off about the xB gas milage. I had a 1986, 124WB Ford Econoline with a 4-speed on the floor that got 28 MPG after I put an airdam on the front!:? :? :?

I wasn't saying lowering the car upsets fuel economy, rather lowering the car upsets your fuel guage reading.

I wasn't saying lowering the car upsets fuel economy, rather lowering the car upsets your fuel guage reading.

I was throwing in my 2 cents. But if the car is still level how would the gauge be affected? :roll:

He was saying that some people are not level, such as with the Tein S-tech, Hotchkis, or RSR springs. For example, the RSR drop is about 2" in the front and 1.2" in the rear. That's a pretty noticable difference.

But of course, when you fill up the gas tank and it says you only used 8 gallons... even if your trip meter only says 260, you're still getting over 30 MPG, so that's really a moot point.

You know, EPA estimates are never right. People keep freaking out about how they're not getting 60MPG in their Priuses, but they should just get over it. There are just too many factors that come into play: driving style, location, temperature, load, modifications, thermonucleic proton deflecting particle density dividends... ;)

You know, EPA estimates are never right. People keep freaking out about how they're not getting 60MPG in their Priuses, but they should just get over it. ;)

Just like why we bought a Scion.. style, safety, etc etc etc..
If you live downtown and drive in bumper to bumper all the time, get a Prius. Save money. If you live in the boondocks and drive 80 MPH, don't complain that it's the same mileage as... oh, lemme take a shot.. a Civic? :evil:

my civic got over 30 mpg even after 225000 miles.....the box BARELY gets 27 in florida, no hills, expressway 80 % of the time....all under 4 thou rpms....

and for the record, i saw Mytbusters lastnight (caught tail end of it) and they ran 2 of the same casrs around a track one with A/c one w out it on.....the one WITH got 8 MILES less to the tank..NOT a very noticeable diff....just wanted to throw that out there...didnt feel like rereading 3 pages of posts...

got 200miles on a half tank yesterday, switched to lower octane runnin on 87 now

I have been disappointed with MPG since day one. My gevetching is well documented in the archives.

I have stock everything -automatic - have yet to modify the interior as I want. Usually I'm the only one in the car (170 lbs). I keep the tire pressure at 36 psi. I drive like a granny (70 and under) and have never redlined it.

MPG sucks and is getting worse. During break-in (up to 3000 miles) I was averaging 29 miles per gallon, Now, at 5000 miles I'm getting 27 mpg. I live in California, so its not like my car is freezing at night and lowering the milage.
I calculate milage at each fill (# miles / gals)

I typically get 240 -290 miles per tank and fill up at 1/4 tank.

I'm very jealous of folks who are getting better gas milage than I.

[Yea that is about what I get. I am half way through my gas and I am at 150miles. For some reason I expected it to be more since my Saturn gets the same mileage and I thought my Saturn sucked but I guess I never did the math.]

how big is your tank in the Saturn compared to the scion? You may get the same number of miles per tank, but I'll bet the Saturn costs more to fill up. [/quote]

I dont know what it is but I go a week or more on a full tank when befor I filled twice a week. I would recomend this resistor chip, its cheap, it safe, it adds 14-20 horsepower and U get better gas milage. My theory is that the xB is heavy for that small engine and our stock engines and sensores don't let enough oxegen and gas into the engine to push it up to a satisfactory speed with a low rpm. so this modification increases intake = horsepower without shooting up rpms burning more gas per second. i purchased this item from ebay it came with simple instrucionas and its simple to install! Please ask me any questions.

Interesting claims CaliMan but a lot of people here seem to disagree.
Please prove us wrong and provide data and links to information.
We would love to have a product that can boost our MPG and HP.

33 mpg's today. Used a calculator.

You know, EPA estimates are never right. People keep freaking out about how they're not getting 60MPG in their Priuses, but they should just get over it. There are just too many factors that come into play: driving style, location, temperature, load, modifications, thermonucleic proton deflecting particle density dividends... ;)

I know someone getting 75MPG in a Prius...he never drives long enough going to work for the gas engine to start up...but thanks to rush hour on the way home taking 35 minutes it gets charged up.

i just got 290 on a full tank. wouldda been like 330 or more but i decided to race some peeps and drive like a jackass. so u know. i got 190 miles at half tank but then i started driving like a dumbass so ya know.

I live in California,

Cali gas is oxygenated to burn cleaner, but it cuts the mileage...

Any tech guys/gals have an opinion on the airsensor chip mentioned above? I've heard this on a commercial.. but wondering if it's legit..

Do you honestly think some guy on eBay figured out something that is UNIVERSAL to all cars yet the car makers with their millions in R&D couldn't do with their OWN engines? And even if Professor eBay did find this miracle cure, why wouldn't the car makers just add it for $8 bucks and gain all this HP that is very important to some carshoppers?

C'mon, use your common sense, do you really think you'll gain 15-20 horse power and at the same time use LESS gas? From a generic resistor that's going to outsmart the very intricate ECU?

Look at it another way, what if your engine chunks after using it for a month because the air/fuel ratio has been altered. What's their guarantee? Oh yeah, they'll give you your $8 back. You can just hand it over to your dealer with the rest out of your pocket...

JMO, but think about it...

ummmm its called regulated emissions! they program the computer to use the least amount of air/gas ratio to reduce emissions wich results in low air/gas intake ratio which results less horsepower. Its simple but logical! Don't deny the chemisty of things untill you proove it ineffective. I notice a huge differance in my car. If you wanna try it I'll send you one. just so you can see if it works!!!

This chip is placed between the air sensor and harness. what this 3.3ohm resistor does is sends a signal to the computer that air is currently 32 degree's. pushing more gasoline and air into your car will not effect your engine. This mod does not make your engine light turn on like other chips do. Jet chips cuase engine problems, overwhelming signals for heavier gas / air ratio's. Plus they are all different specs for different cars. xB require 3.3ohm resistors. this is a simple change in engine chemistly letting the engine computer do the rest of the calculations! This chip is easy to instal and remove. all you need is electrical tape and 10 minutes to the let the engine run. I'm willing to send 5 sample chips to your guys as long as you give me your feedback!!! first five must pm me to get on the list!

I have been disappointed with MPG since day one. My gevetching is well documented in the archives.

I have stock everything -automatic - have yet to modify the interior as I want. Usually I'm the only one in the car (170 lbs). I keep the tire pressure at 36 psi. I drive like a granny (70 and under) and have never redlined it.

MPG sucks and is getting worse. During break-in (up to 3000 miles) I was averaging 29 miles per gallon, Now, at 5000 miles I'm getting 27 mpg. I live in California, so its not like my car is freezing at night and lowering the milage.
I calculate milage at each fill (# miles / gals)

I typically get 240 -290 miles per tank and fill up at 1/4 tank.

I'm very jealous of folks who are getting better gas milage than I.

240-290 miles per 3/4 tank is 30-36 MPG (using 8 gallons as a divider)

I filled up for the second time, and averaged 31 MPG. Only have 538 miles of the box.

The xB tank holds 11.9 gallons so 3/4 of a tank would be closer to 9 gallons (8.925 gallons exactly). So 240-290 miles would mean 27-32.5 MPG. (But factoring in the fact that the odometer reads about 5% below actual mileage means that the true MPG is about 5.25% higher or, in this case, 28.4 - 34.2 MPG)

However, one should not depend on the gas gauge to figure out how many gallons of gas are used but base it on actual fill-up amount. (My gauge seems to read low, i.e., shows less gas than there is in my tank.)

I'm not quite sure how much this matters but Scion recommends 29 psi for the tires.

WeirdScoinz - thank you for clarifying my post to others.

My typical driving tank = 27 mpg (again, I calculate mpg # miles divided by gallons to fill tank). I get 31 or 32 mpg when on freeway only. I was expecting over 30mpg for typical driving and 34-35 for freeway only.

My 1995 Escort (RIP 2004 - cracked head) got 32-34 mpg city and 38-40mpg highway (98 hp, manual trans). I think it must have been a "special" Ford. Everyone else I know _never_ got that good milage.

I bought the xB for the space and the high mpg. I still feel let down by it. Especially as the mpg is going down since break-in.

BTW- Took it to dealership at 5000 for oilchange and asked about the poor mpg. They just stared at me and said "sounds like good mpg to me." GRRRRR.

The xB is _very_ sensitive to the type of driving you do. In our normal "working" cycle with a lot of stop and go, the car gets 26-27MPG. When we go to "vacation" cycle, like this week, we mostly drive across town on 50MPH streets with fewer lights and get about 30MPG. On pure highway driving with few stops we get about 34. These numbers seem reasonable for a relatively heavy (for its engine) and boxy car.

Man some of you guys are lucky to get past 220 miles per tank...i only reach up to 210 and then i need to re-fill .....thats what i get for going with 19' wheels...:D...im happy though...if i do go on road trips ill leave my ride at home....

i think that ford was a factory freak motor. people say i have a factory freak motor cuz they seem to think i have a fast box.

Put the windows up and only drive downhill! :lol:

Another thing about the stated fuel economy of the car is that the highway rating is tested with an average speed of 48 mph, so unless you regularly drive like you are supposed to during the break-in period you most likely will come up a little short

It was painful but I followed the break-in to the letter which even included taking backroads to Skyline drive! I wanted to get that break-in done in a week. I now have 28K miles since June 04. Without any mods at that point, I really didn't feel compelled to race out in front of traffic anyway.

212 miles yesterday going to Phoenix/Tempe/Mesa 6.6 gallons of gas used. Speed average of 80 miles per hour rpms 4000


gotta love the box my matrix would use 3/4 of a tak of gas...

I'd kill to get that. I did one time, forget how. I think it was cause I was just cruising at 70 the whole way on the freeway. Ya, it was going to and fro Disneyland, lol. It was rad. I drive way too fast/crazy to get that every fill. I always say i'll slow down, but I just have speed in my blood, with a car that doesn't wanna go fast, but ya.... it's fun pushing it.

I got a $140 ticket in my box so I've learned to drive a bit slower now. :?

only $140? How fast were you going in what zone? Prolly cheap too cause you're in MD.

The only ticket i've gotten was doing 58 in a 45 (going downhill) in my old 95 Civic, the cop was totally hiding too, it was lame. That was just $120 though, but it's still pretty cheap.

I noticed that my gas mileage has gone down significantly since the cold weather has hit. I averaged about 32mpg (mix) and now I get 26mpg. Has anybody else noticed a decrease in real cold weather?

thats about what i get too

79 in a 55 but I was slowing down from the century mark when I got nailed by a lasergun. :oops: :oops: :oops:
