whats your mpg... i have the 5spd and i am heavy footed and the lowest mpg i have seen was 22mpg

I get about the same as you. I floor it alot tho. :P

300 was my low which netted me 25 mpg mixed driving on 12 gallons

highway was 33 mpg and was 12 gallons as well 398 miles.

Car is a auto TC with under 1K mileage.

Normal driving with a few beatings since it is new.

so the tc is not an economical car

my auto got around 22-24at best. didnt drive that hard either. i dont know what it is. but i got a 5spd and my first tank was around 27mpg. now i average 25 because i dont drive as slow.

i dunno, id get your car checked out at the dealer.

yea i drive most hwy at arourd 80mph and i have some power mods and i still average at least 25mpg and get about 27 if i am all highway

the lowest i have gotten was 25 mpg, which is about 320 out of a full tank. 230 sounds really bad out of a full tank.

Is there something wrong with my car ?

1) Are you on "D" or "3"?

2) What is your engine RPM at highway speeds?

3) If you are on "D", how fast are you driving?

Man,. thats abnormally low, go get ur car checked, I have a auto tC and the lowest i've had is around 22 and thats mostly city driving.

wow...i get 22-26mpg and im TURBOD!

holy crap, 230?? I've gotten 360 miles while doing 80mph with a bike on the roof. when you "only get 230 miles", how many gallons do you put in it when you fill it up? miles / gallons between fill ups = mpg. :)

360 was the most i ever got. and that was with some spirited driving.

I'm in the same boat, I've posted my problem on every damn gas related thread.

My best tank I believe was under 270, usually I get 220-230 a tank.

I've had my car for 2 years and 2 days now =P

i just hit my best at 270.

60% highway going around 65-70mph

40% city going around 30-40mph

i dont step on it much but since its summer here in south tx the a/c is on about 95% of that time?

another thing, dont we have a 14.5 gal tank? Im only getting 12.5 when i fill it up, and thats when the pump thing clicks, i stop when it does that.

we do have a 14.5 gallon tank, your not running your tank completely empty which is not a bad thing.

what grade do you guys use?

87

I average 330 and drive 80% freeway. Avg speed is 75 mph. Usually about 28 mpg or so.

That's pretty crazy. I have a 5 speed and i drive city most of the time and still get around 300 most of the time. I think my worst tank was around 260.

5 speed
Average 26.7mpg during ownership
Typically get 300-320 miles per tank
Drive moderately aggressive

Here is what you need to do:

1. disengage the emergency brake

That seems kind of low for that much highway, the last tank for me(from full to quarter mark) was about 95% city and 5% highway and I was at 235 miles. I normally do almost all city driving and don't drive very slow and average about 200 miles(almost always put in 10 gallons).

Do you do a lot of idleing?

possibly D3 instead of D?

My car @50K miles, got 350 miles on 11.5 gallons of gas on a recent trip to Vegas. That's with 2 passengers and their luggage. 95% highway for that trip with 80mph average speed as well as spurts of 110 mph.

For daily commute in the city, which is 100% city, I get an average of 22-25 mpg.

When my rpm is at 3k my speed is at around 70mph.

I have never driven any car on "3". That's like suicide.

yea there's something wrong with this tc.

How on earth are you getting 580 a tank? Did you get the bigger gas tank mod? Or the smaller engine mod?

580 a tank is what hybrids are getting, I don't see how that's possible in a 2,900 lbs., aggresively geared, 2.4 liter car.

I get about 22mpg city and 25mpg hwy.

My wife's 4cyl solara gets better mileage. It's a heavier car too.

Toyota should fix the gearing on the 08 model. Give it a 6th gear or a taller final drive.

I get soo many comments on many other threads because people don't believe me. But I have a lightweight flywheel, Weapon R intake with ram air adapter, and custom exhaust with 3" pipes. And notice i said "best". I have only seen that twice. and that was goin to VA beach. I drove at night when it was nice and cool, and set the cruise at 70 and there was no other cars as traffic. But on average with only back and forth to work, i have been getting about 32-33 lately. And city driving is about 26mpg.

I know it sounds amazing but maybe my car is different. Like this guy is getting about 10mpg less than everyone, and i'm getting 10 mpg more, im not sure why but im not complaining.

And just for example when i pulled in to my spot at work today, my trip meter said 130mi and was just hitting 3/4 of a tank.

I am now supercharged and I get around 22-24 mpg. Before I supercharge, i was getting 26-28 mpg. Some people need to learn how to drive better.

So is it the flywheel that makes that much of a difference?

So is it the flywheel that makes that much of a difference?

Personally i believe so. At first with just the SW WR intake i was getting about 26-28 highway at best. Then with the addition of the flywheel, im now seeing 28-30 highway when i romp on it all the way home(70-80-90) and 32-33ish and even more when i can use the cruise, I would say that my good mph is alot to do also with the cruise.

I been nhittint 330 miles on my last couple of tanks

wtf? i get 100 to half a tank... but thats with ALOT of idleing... normal?

Take it to the dealer. I almost get 100 at 3/4.

i get like 150 miles on 6 gallons.

just use 93...for the price youll fill up less. plus the car will run and sound better.

No it won't.

Octane is a measure of a gasoline's tendency to autoignite.

The manual says 87, and there is no reason to put anything higher.

Higher octane gas is just a waste of money, and the gains you speak of, are just a placebo effect of spending more money for gas.

right...so explain the 360 to the tank compared to 240 with 87...

Different driving habits
Highway vs. city
Cruise control vs. manual input
Humidity differences
rainy vs dry
hot temps vs cooler temps
road conditions (bumpy or smooth)
difference in car weight due to payload
tire pressure
different fuel additives (different fuel brands, not fuel octane)

should I continue?






And yes I know most of those factors I listed above wouldnt make a 120 mile difference, but scientifically speaking, higher octane gasoline will make no difference in mileage with a naturally aspirated tC engine that's engineered to run perfect on 87 octane fuel.

I have an auto and I have never gotten less then 300 on a tank and I have been upwards around 400 on a tank. I even get on it every now and then too :)

Yesterday, I was at at 130 at 3/4
Today, now im at 215 and have about a quarter inch to go until i hit 1/2 a tank

I know most people don't believe me, but i swear to God its the truth. There is nothing gained by lying about mileage.

i think someone is filling your gas up at night time while you are sleeping.... :P

Did you use the amount of gasoline added in or the tC's fuel tank capacity to calculate MPG?

Idling really doesn't bring the gas mileage down much. I play xbox in my car sometimes for awhile with the car running (especially during power outages from hurricanes) and I barely notice the gas mileage go down at all.

i'm 80% highway/20%city.


Is there something wrong with my car ?

i rarely floor it. Drive it like a grandma most of the time.

Well i get about the same depends on the .. week lol.. and the other's are 270 is the most.. hehe .. but when i slam on that gas 190 is the most.. hehe :bow:

Kdog and Keitaro...

I would be ok with that!!(someone filling my tank at night :rofl: )

I almost always go til the light comes on and i put in about 11-12 gallons, but to calculate, i always count how much i put in and divide that by the mileage on my trip meter.

I typically get 350-380 miles per fill-up. 85% highway at 70-75 mph.

^ roughly 32mpg, not bad compared to the others on here

my first tank of gas went 310 miles....im just now im my second tank of gas...it is alot better thank the corvette i had

Well, I've had my car for exactly a year now. Put CAI on it at about 3k and have had the TRD exhaust since day 1. Anyhow, I just wanted to say that I have always managed to average at least 300 mi. per tank. Different gas, mods, etc. have had little if any effect. I ususally drive about 50/50 city/hwy, and I do see numbers about 320 when it's mostly hightway driving. Also, I do some very "spirited" driving from time to time. Finally, I always fill my tank until the pump stops, and usually run it about 20 miles past the point where the light comes on.

I would say that if you're not getting more than 265 miles to a tanks, something must be wrong. I would try resetting the ECU, and if that doesn't help, talk to the dealer. Also, I'm not sure that I would use a "half tank or 3/4 tank" measurement whatsoever. I can often put 60-70 miles on a tank before the needle even moves much. The last half of the tank definitely drops a lot quicker as well. I think it is ill-proportioned just to give the driver a little "scare" before they run out of gas.

Anyone else here have an 05 tC, not sure if that matters at all but i heard somewhere that they might be a little different in the way of AFR. Not sure about that though, and plus my cousin bought a tC because he liked mine, but he bought an 06 and only gets about 22-24mpg and with his unichip in he only gets about 18-19

I have an '05.

RS2 5-spd here. TRD exhaust only mod. I drive about 95% highway 5% city. I fill my tank at about the 3/4 mark or below, but always before the light comes on. I bought the car new in June. i put in about 10-12 gal when i fill up. highway is avg 85-90mph. first 4k miles i avg about 23-25mpg now i avg 25-28mpg (@8550miles). i have a LEAD foot and drive hard.

tCizzler, assuming you fill up at most 13ish gallons on those 580 mpg tanks that puts you at 44mpg.....16mpg over the rated top mpg. but i would hope you dont let your gas get that low before you fill up anyway which would greatly increase that number. hard to swallow that number....its down right not edible. that is something i could not take anyone's word on, not even my closest friend with out seeing it.

tCizzler, assuming you fill up at most 13ish gallons on those 580 mpg tanks that puts you at 44mpg.....16mpg over the rated top mpg.

Not a chance a tC is getting 44mpg..

tCizzler, I'm not buying it.

Ok, I just bought my car 2 nights ago. I have already drove 220 miles(girlfriend in SD) and I am barely at half a tank. My 240sx got 260 a tank.

I <3 tC!!!!

Its ok i understand if you guys don't believe me, sometimes i don't believe it either, and i can't prove it to you, but like i said that only happened twice and they were pretty ideal conditions. On average i get 32-33 highway(without trying).

Check out what evil tt wrote... 220 miles and barely at half tank, thats about 32MPGs also(no mods)

I'm not trying to brag and say i can floor it everywhere and get 40+ mpg, i'm just saying in perfect conditions, it did happen to me twice. Both times were going to VA beach to visit my cousin.

i'm 80% highway/20%city.

HAHA same here but busy in the afternoon and not so much in the morning. Can't wait to see how that wrap works for you!!

Ok sorry, anyway back on topic....

You guys do alot of highway driving.. I haven't been on a highway in about 4-5 months. I guess it's all that city driving that is killing my MPG.

Yeah, the weight of the car doesn't help in city driving. Highway gives you the ability to use the momentum of the overall weight coupled with the power of the engine. Less gas usage that way.

Ouch! I thought my mileage was bad. The best I've gotten in my car has been 287, but from threads I've read the gas mileage has been one of the better qualities of the car.

haha, you sound just like me!! I work the old office corporate job and work mostly in the mornings and free up alot of time too. I'm getting really bored post-auditing CMF forms so Im taking a break right now. They pay really good and I wish It could all go to my car but man.....the girlfriend (a.k.a. ball and chain) is where all the $ go's! Dinner, movie, movie food($$), gas, and liquer (ME-capt. morgan tattoo/GF-Aftershock & vodka & crannberry) puts a nice sizes hole in the bofa account. Does anyone else spent way too much on sushi too?

Wow am I the only one?

I drive my 07 TC for pizza delivery and am on the highway say 90% and in city maybe 10% with frequent stops in city and i go threw a tank of gas roughly every 2-3 days depending on how busy it is, and i'm getting near 27-29mpg and pusing near 360-390ish a tank! The first day I bought my TC with 18 miles on it and I filled it 3 days later @ 365 which was right when the light came on and usualy around i believe 2 gallons left.

^^ 97 tC, eh? Man you must have hookups over at Toyota :P

The most I've gotten was 250

waht will the dealer check for if we take it to them for low gas mileage...

your not running your tank completely empty which is not a bad thing.

I learned at the new owner's meeting at our dealership that it's bad to run your tank completely empty because then your sensors are exposed and can heat up; keeping your sensors constantly "wet" with gas is the way to go.

Am I right?

as far as i know, the "sensor" is a floating ball, so no, you are wrong.

Am I right?

I believe the reason running on a near empty tank is said to be bad is because the junk that settles to the bottom of your gas tank can get sucked into the fuel pump when you get down near the bottom

Not sure how true it is, but really there's not a reason to be running your car with no intention of finding a gas station soon when you get near empty and/or the gas light comes on

Actually running the tank to empty hurts the fuel pump itself, the fuel that is in the tank help cools the fuel pump. Running the tank empty leaves the pump with out a heat exchanger and risk premature wear and tear on it.

PUMP is what I meant, not the sensor! sorry... thanks trialsindude

you dont want the crap that settles at the bottom of the tank sucked on either, its best to fill it up at 3/4, or atleast before the light comes on.

^^^at 3/4? Did you mean 1/4 left?

thats really low, i consistantly get 300 miles a tank and i drive 60% sidestreets 40% highway and i push it once and a while

first off.. something is defiantely wrong with your car. good luck proving it to the dealer tho, they will do a ___ "fuel consumption test" and your car will most likely pass, and they will tell you to lay off the accelerator.

and to the guy who says he got 580 on a tank twice.. IT IS A LIE. you said you average 32-33mpg.. with a 14.5 gallon tank, the MOST you can get is: 480.

and thats still more than anyone has ever reported.

i have an auto with I/H/E and 18's and i average about 25-28mpg and get about 350 per tank.

so something is wrong with yours.

I get 410 on a tank ...i drive 125 miles a day its about 30/mpg i stomp on it and everthing

and to the guy who says he got 580 on a tank twice.. IT IS A LIE. you said you average 32-33mpg.. with a 14.5 gallon tank, the MOST you can get is: 480.

and thats still more than anyone has ever reported.

Thank you for telling me how my car works :bow: , it means a lot to me.

Ok so now "average" means sometimes more, sometime less, right?? Seems common sense to me. So how is the "MOST" i can get 480, when i just said that was my AVERAGE.(100% highway, not my average on city streets). You said, "and thats still more than anyone has ever reported", well guess what? NO ITS NOT, i just reported more!
If you don't believe me, then you don't believe me, and keep it to yourself or ask questions, but don't call me a liar. I have no reason to lie and don't care what you think, this site is supposed to help and thats all i was doing, oh well, im done defending myself. Sorry if it seems like im outbursting, but i am a very honest person and i don't take it lightly to be called a liar. Good bye

Either way, to the guy who started this thread, there is something wrong with your car.

UNSUBSCRIBED

580?!!?!

That is 40 MPG if you run it till it dies.
If you run it till 14 gallons used so that it doesnt die. That is OVER 41 MPG.
Not to be a skeptic..oh wait...I guess I am...But it sounds fairly impossible.

i just got 360 miles out of 12.8 gallons, which is just over 28mpg's. i also let my car sit and warm up for like 2-3 minutes before i even put it in gear most of the time, which takes gas and doesn't put it into miles. i did a little bit of highway at good speeds on this tank too.

i could easily get 30 mpg's in my car if i was easier on the gas but what fun is that. if your only getting 230 miles out of a tank and your running it close to when the fuel light turns on then you have a serious problem.

wow more 580 miles to the tank thats complete BS. I know for sure I pulled 33mpg before though which will be 475miles from full to complete empty.

IN other news:
Even with running the tank to empty and worrying about picking up crap that settles at the bottom, the fuel pickup is at the bottom of the tank with a mesh screen. But with a tank with more gas in it, all the sediment is being slosh around its less likely, but if it was to pick something up it will.

I'm averaging about 350-380 miles on one tank. 230 you got issues get your foot of the gas pedal.

I average about 26mpg, About 290 til I refill..
60%hwy 40%city

5 speed, shell fuel only.

Switch your fuel and I bet after 2 tanks of a different gas, you'll gain a bit more mileage. Try either Chevron or BP. 290 is still pretty low for the 5 speed.

My fuel light came on at exactly 260.0 miles today. Got gas, worked out to 21.0 mpg. I drive all suburban no highway. Mobil 87 10% ethanol. I have a '07 auto trans, this is the third tank of gas for the car.

The most I have ever gotten was on the way back from our family vaction in NM which was 790 miles from our house and I only filled up once the whole trip and I got around 300 miles out of the first half of the 1st tank believe it or not. But it is also mostly downhill and it was an optimum temp of 75 the whole way. I went 540 miles before filling up and my gas light had just come on. Again, it was all downhill and great temps and it was ALL highway. I normally get about 400 miles to a tank and I drive pretty harsh.

WERD! Now thats about what i get and no one believes me (my above posts), so i'm glad to see someone else claiming mileage like me. I have seen 40+ miles on long cool highway trips also. HAHA finally someone else

hey everyone
i also get about 230-250 miles to the tank. i went to the dealer and the man told me if the check engine light isnt on then theres no problem. i told him that i read on scionlife that people are gettin 400 miles to the tank and he said thats impossible... :eyebrow: im going to head back later on to ask someone else, as i didnt have time today, but anyhelp to fix this would be appreciated

The best that I have done is 360... OC to Parker AZ and around town, but that is the gas light being on.

Normal I am 60% city 40% highway I get about 260; when I was driving 80 miles per day (round trip) I would get 310 or so, but that was also with the light on.

Are you a little heavy on the peddal? Keeping it over 3000 rpm will kill your mpg.

Well I have filled up 3 times. The last 2 I kept track of my mileage.

Today I pumped 10.86 gal when I had driven 239.7 miles since my last fill up. Thats 22.07 mpg

Last week I pumped up at 10.61 gal when I had driven 261.8, calculating to be about 24.67 mpg.

Differences between today and last Friday, higher temps causing me to turn on my A/C more. Also I've been in much more stop and go traffic then last week (bleh!).

I drive a 2007 Scion tC AT

I mean daaaang. Unless my gas gauge was messed up for a day, which I am sure that it was not.

do you think those engine cleaners or fuel injector cleaners can help?

i have about 32000 miles, auto, and drive pretty calm.

all of the maintenance was done on time.

thanks!

having the AC on has shown MINIMAL effect on fuel consumption (i blelieve they showed it on an episode of myth busters once...). in fact, having the sunroof open on highway speeds will decrease your MPGs more....

i dont think i've ever gotten less than 25 mpg....

Lowest I've gotten was ~240 mi per fillup which is about 21-22mpg but that was cause I had recently installed a DIY CAI and Progress Rear Sway Bar so I was driving like a mad man. If I'm nice I get 26 all city and 33 all highway.

Last two fills were the same as my first for my commute to work in stop and go with a longer lengths but definately no hwy.

300 on one and 312 on the other both took 12 gallons. So I am getting about 25-26 mpg.

I see no reason others cannot get that or slightly under it with decent driving and mods that are done properly and that do not hurt mileage.

Also saw no gains using 93 octane over the 87.

Who knows what I will get on a strickly highway fillup.

recently got 31mpg going from NY to DC and back. And that includes driving around town in DC, and being stuck in stop and go traffic on the NJ Tpke and I-95.

avg. about 75-80 mph usually, cruised whenever i could. had gone 367 miles before the light came on.

alrighty i just got my tC friday 07 auto

they gave me a full tank then and 4 days later i was at 260 miles and the light came on. i filled up and it was 12.6 gallons to fill.

the real test will be this thurs when i go 200 miles all highway im gunna fill up right b4 i leave and once i get there to see the exact mileage

cuz 20 mpg is bull____. i dont know if its just the engine breaking in or what, but that ____ has to stop 70% highway

dude i just got 190 on 100% city driving (OC). wat the hell? i have 30k miles on an 06 tho. (handed down to me from parents after we sold my benzo :( ) haha

im due for an oil change now and probably filter change too cuz it looked dirty when i checked it today...anyone got an idea???

I mean, those getting poor mileage per tank, are you all in the "break-in" period? Cause in the beginning it should be fairly low but afterwards you should see improvements.

my 07 auto tc 2 weeks old
i filled up my gas when there was 1/4 left, it had 270 on it. the second tank i got 290 sth on it. i think the current tank of oil can hit 300 b4 the tank with 1/4 of oil left..it seems not too bad for me :x

07 5spd tC
High = 340/full tank
Low = 260/full tank

Even all city driving, how the hell are you all getting lower than 300 miles to a tank? At my very worst (with 1/8 tank left) I got 315. I always get around 340-360 easily and that's after all my mods. That's rediculous.

I just got 260 to a tank.. 100% city driving with about 2 hours of idling time. Not too bad considering my extremely heavy foot.

Wow, it's just very hard for me to imagine that little mileage. My truck got better mileage than that. That's why I got the tC. Not sure what's going on with your engine to give you that crappy mileage. That's the lowest part of the expected mpg. Around 20-22ish.

I probably bring it to redline about 10 times a day. That will drink some gas.

I never drive on the highway and lately I've been playing xbox on my lunch break while the car is idling.

I think the sticker only said 22-23 mpg around town when I bought the car. That's probably right about what I'm getting.

Yeah, but that still sucks. The mpg ratings are high end and low end avg. Sucks that you're in the low end average. I'm at around 23 in the city and around 26-27 on the highway.

What oil do you use and weight? Heavy oil has a disticnt impact on mpg too.

5w30 Mobil 1 Full Synthetic, I change it every 2,500-3,000 miles.

Damn, guess you just got one of the tCs that run near the bottom average. That bites.

the last tank of gas i had went 330 miles:that is 50%highway and 50%city. and i drive almost everywhere i go at least 60 or 70(even in city) it lasted me a week. this one wont be that much i dont think

just got back from a trip upstate, 80mph w/ 2 bikes on the roof. 26.9mpg. usually get around 300-320 miles per tank, highway driving but with a roof rack to add some resistance.

YMMV

im consistently getting 325 miles on 12.4 gallons... not bad i guess..

Cruise control with no AC on does make a big difference. When you get up to speed and leave the cruise on, your engine is literally sipping at your gas tank like tea from a teacup.

The ac button sucks power from cars that people just don't believe, in 4 cylinders it really does make a considerable difference for mpg. Try it sometime, drive an entire tank with the AC on, then an entire tank with the AC off.

Also, octane has nothing to do with mpg as PunkInDrublic says. Hey, don't believe me, but go do research on it and then come back and state your opinion either way. :)

So far I've only filled up my tank twice and my mpg is averging 25 (I drive pretty hard and about 85% has been city). Also, becareful how you measure your tanks guys. Remember, 14.5 gallon tank... fill your tank to full, set your trip odometer, then drive until you refill. Count how many gallons you put into the car on the second tank and subtract the difference from 14.5, then divide that number into the number of miles on your trip odometer.

No offense but on a few people it sounds like their math was just a little off, or they weren't doing the formula correctly. If you really are getting only 230 per tank, you have something very wrong with your car, go get it checked out.

^^Agreed.

Octane is something touchy, but for the most part, there is no increase in performance from higher octanes. The only contradiction to this is with Forced induction. Higher octane is essential for a more consistant burn due to the higher amounts of O2 in the cylinders.

Damn, guess you just got one of the tCs that run near the bottom average. That bites.

It does seem to get crappy gas mileage compared to other tC's.. But it also seems to beat other tC's with very similar mods. There are several people on this forum with almost the exact same mods trapping 1-2 MPH less then mine.

I haven't been beat by another tC around here yet and some have had more mods then me. Maybe it's a factory freak.

I'll trade some MPG for some MPH anytime. :)

i REALLY dont think AC makes a huge difference. especially if its a debate of whether to ride (on hwy) with the AC on, windows closed vs. AC off, windows down.

... fill your tank to full, set your trip odometer, then drive until you refill. Count how many gallons you put into the car on the second tank and subtract the difference from 14.5, then divide that number into the number of miles on your trip odometer.

why is there subtraction involved? i simply take (miles on trip meter)/(gallons i just put in), am i doing something wrong? and never ever never ever never ever top off.

We all have different driving habits and different driving conditions such as temperatures mountain vs flat land etc that we drive in so this is not a real accurate comparison as to gas mileage. Also many people don’t know this but different states have different requirements as to what is in their gas. I am so glad I don’t live in California any more. The MTBE in their gas caused a decrease in performance and mileage for me glad they don’t use it anymore. There are also different gas formulas for winter and summer driving. Different gas companies use different additives to clean out the engine among other things. Below are a few of my observations and my .02 cents on this issue.

1. My 07 tC went 327 miles before the gas light turned on. With its first tank of gas in it from the dealer. About 50% highway 50% in city driving. I also treated it nice to break it in so no quick starts and I didn’t go over 60mph on the freeway.

2. I also saw that myth busters episode which showed that AC does not cause the consumption of more gas when it is turned on.

3. The type of oil you use will make a difference as to the amount of gas mileage you get the 5w30 mobile 1 is awesome stuff. I have experimented with this and tried it out vs how regular oil works in your car. Try it for yourself.

4. Idling your car will use up gas. I have remote start on all my cars and I noticed that after I installed it and use the feature by starting and idling the car for 5-10 minutes of warming up my car everyday it did cause me to get poor gas mileage. As an experiment I went a week without remote starting my car and gas mileage improved. In the cold Washington winters I rater use it than get better gas mileage.

5. Where you get your gas makes a difference. I have been to an old Chevron station and I only got 200 miles out of a tank in my xB. Try to find a gas station that has recently had its tanks changed, or has newly been constructed. Go to a quality gas station Chevron, 76, or Shell are my favorites. Also as a test a few years back in a previous car I owned I went to an independent gas stations and an Arco (only once to prove a point) and compared the gas mileage I got to using Chevron 76 and shell. Took a few weeks but my sister and I had an argument where she believed gas is gas and it didn’t matter where you get it from she wanted to use the cheap stuff….. she was so wrong! I got about 1/3 less miles when I used the Arco. And the independent station was less as well. Chevron 76 and shell were all about the same.

Has your tC always had such poor gas mileage or is this something you noticed recently?

i have gotten at best a lil over 400 miles that was some high way and some stop and go. a pulled like 30 mpg or better

i went to niagara and back from chicago around 1100 miles on three tanks, auto trans and i wasn't going that slow 90 100..

i have gotten at best a lil over 400 miles that was some high way and some stop and go. a pulled like 30 mpg or better

Yeah, I've gotten close to that. Best for me without making the tank dry was around 390. I think I could have done it to pass 400 but just didn't want to risk running a dry pump.

first fill up on the wife's tc yesterday: 335 miles 13.09gal = 25.59mpg's. not too bad. If I were driving it I would be lucky to break 20 lol.

Do you suffer from heavy foot syndrome also?

Oh Yeah!! and after driving the xB for 2 years I need the fix!

Understandable. :P

Oh Yeah!! and after driving the xB for 2 years I need the fix!

Me too, same problem!! Looks like we got about the same mileage on the tC in WA.

[b]i have an automatic
im at half a tank right now
and im at 215 miles
and its been 50/50 highway city
i floor it sometimes
and i drove in the fast lane.... :bow:

There are so many threads about people complaining about the tC's mileage. I drive it normally for the most part and during summer months, I get over 200 miles at the half tank mark.

On the highway, I typically drive at 70mph (65-75) and I get very close to EPA mileage. Even in pseudo-city driving, I get over 22 mpg. Surely there are other people out there who're getting good gas mileage.

I could get 30-31 before I got the supercharger. Well timed lights (hitting almost all greens) on city streets I could average about 55 mph. Even now I get get about 27 mpg on the same route.

I've been setting the trip-o-meter everytime i go an fill up now and I always run it down to where it need damn close to 12g to fill and i've been getting @ 75%city | 25%highway above 300 miles every time. Highest being close to 360-380ish (went across the state doing no more than 70mph and used cruize control like ti was my job)

Highest # of miles I got to a little bit below the refuel/empty line was about 370. Would be tons better if I hadn't gotten stuck in traffic/didn't go above 65 mph.

my trip comp is at 320 mi right now and I still have little above 1/4 tank..

I drive in 5th gear going 35mph, and try to time my ride so I never come to a stop at lights or in traffic.

Driving all highway in my 5spd I got 37 MPG!! That was driving the speed limit with the cruise set. Before I would set it 5-10 over and I only got 27. Driving the speed limit really does save gas!!

I drive an hour each way for work and with the light on I get about 340 to 350 but that is with fumes. Now when I drove from the Houston area to the Washington D.C. area which is about 1600 miles. I got over 400 miles to a tank doing 80mph with a full load of crap in the car.

something must be wrong with your TC 230 is already less than 20mpg for 12 gallons...way way too low. my worse mpg was 25mpg and that was because I put on turbo and i floored it a couple times.

My last few tanks got around 300 miles on 12.75 gallons each.

everyone has very different outcomes. Im getting about 250-65/tank @ 12.5gal. Ive never hit 300 with no engine mods and an axelback exhaust with springs (dont think springs have anything to do with it). I wish i got more but...?

I only have cai.
