Are you writing down the miles and fill up amounts? Or going off the numbers on the dash? If you're doing the first and still haven't seen an improvement, I would go to the dealer and have them figure it out. Its under warranty so you should take advantage of it.

 

I still have not bought a scion and this is the thing that worries me abou them. There is the occasional person that cant get better than EPA no matter how they try. It is something like 10% of owners. Then there are the people consistently getting 36+ in an xD and 30+ in an xB. www.fueleconomy.gov owners are reporting almost 29mpg in xB2 and almost 34 in xD

 

I write the numbers down. I do not read the dash numbers.

I've calculated 3 tanks:
27.6 mpg (2/3 highway, 1/3 city)
26.4 mpg (2/3 city, 1/3 highway)
26.9 mpg (1/2 city, 1/2 highway)

Thats a 27 mpg average for 50/50 city/highway.

Scion says that automatics get 26 city, 32 highway. An average of 29 mpg, if both are traveled equally. So I'm about 2 mpg less than that, which is understandable because I have larger than stock wheels. I see no point in taking it to the dealer because they'll just tell me what I've already said.

 

I think fueleconomg.gov is the best thing to go by, not by what people are reporting.

I for example will pretty much get the exact mpg that site says if I just drive normal (I have an XB2 though). If I try to get better than it, I can. I can and have gotten 25 mpg pure city just by using cruise control more and being more aware of how I drive. I'm sure you could get even more by over inflating your tires and hypermiling and what not though. Of course you can get worse if you're hard on the gas. When I fill up I generally end up getting 22mpg (99% city driving) just like the epa advises.

So go by fueleconomy.gov as your basis of what these cars get, and realize you can get better if you really work at it, but for the most part, you are going to get what that site says.

 

>>So go by fueleconomy.gov as your basis of what these cars get, and realize you can get better if you really work at it, but for the most part, you are going to get what that site says.

actually what i was refering to was the individual estimates on fueleconomy.gov For the 2008 Scion xB manual, users report an average of 28.7mpg but the epa rates it at 24. If i got 24 that would not be so good, but if i was getting 29 id be relatively happy with that.

I know some of you are going to say just get the xD if i am that concerned with economy, but i dont know how i feel about the safety of teh xD. It has such a small trunk area and i think if i got rearended by something big and heavy, the car would not have enough crumple zone. The govt doesnt even test rear impact for some reason and the IIHS only tests rear impact at a measly 20mph with a car of the same weight. But where i am, about 50% of the cars weigh well over 4000lbs and they are likely to hit faster than 20mph. The xB has the extra size and space to make me feel better about a rear impact. Way more crumple zone.

I really like the xB but im not sure if i will get the economy i am looking for. But the other alternatives are impractical or less safe.... bummer.

 

When I say fueleconomy.gov, I mean the epa estimates on that site (not the individual estimates on it).

Just a FYI, go to fuel economy.gov and do a "compare side-by-side" where it shows both the xB and the xD. Now change "Use Your Gas Prices & Annual Miles" to show how many miles a year you drive and your driving preferences (80% city, 10% highway, etc.). This will allow you to see what the price in gas will cost you for each vehicle.

For me, at 15,000 miles a year (which I don't drive, but wanted to overestimate just to make sure), the xD only saves about $300 a year. I was more than happy to pay $300 a year to get the xB. Your results may vary though.

 

I am getting similar milage to you. Also on 18's. Although I did get 34.5 on my trip back from maine on gasoline sans ethanol, I am not seeing anywhere near 37 + mpg that others are reporting.

I bought my xd in august of 07'. I have almost 14,500 miles on it now. I know for a fact that pure gasoline with net you 2+ mpg, but that still dosn't account for these vast variences in readings. I wonder if other brands see this kind of spread in averages.

My driving habits are more about taking corners with some enthusiasm than pure speed. Although I do like to go 70-80 on trips, thats only on the interstate with no traffic. Otherwise it's 65 or less on the freeway.

I was shocked to see what others were reporting for mpg's. I know that some is user calculation error, but there is too many people getting 37 plus. What gives?

Scion won't do anything because we fall within the parameters of the sticker 29-33 for me and I believe an auto was 28-32 IIRC.

I love my car. I want to get the kind of milage others are reporting too

 

IMO, some people are fudging the numbers. The EPA for an xD is roughly 30 mpg when traveling 50/50 on highway/city. The 35, 36, 37 mpg's seem too much. I wonder if it has to do with the slight competition between the honda fit, yaris, and other subcompacts that get better gas mileage? xD is kind of the underdog, so owners do not want to admit inferiority.

 

I think that the manual vs automatic makes a bit more of a difference than the 1 MPG on the window sticker. All of the ~40 MPG xD's I have seen are manuals. Run on the stock tires with high pressure and possibly synthetics in the engine and trans. Also driving ~65, not 70-80.

It would be REALLY helpful if everyone who posted to this thread stated whether they were driving a manual or auto.

I doubt the owners are fudging the ratings to make themselves feel like they are superior to Honda Fit drivers.

 

I guess you never bought one???

Why are you commenting with conjecture and heresay?

" It has EPA fuel economy ratings of 27 mpg city/33 mpg highway for the manual transmission model and 26/32 for the automatic."

from http://www.autoblog.com/2007/07/13/s...red-at-14-550/

Please, no doubting, just comment on what you know.

I really don't know who is doing what here, I just find it weird that there is such a descrepency in #'s. It's a little troubling and I for one want to get to the what the truth is.

I wholeheartedly believe some people maybe getting these great #'s, I just want to know why.

Ok, so I've got some investigating to do, lol, this should prove educational.

PS- I am running on 18's with a manual shift.
I am running with Alisyn oil (http://www.aerospacelubricants.com/)
great great motor oil, fully synthetic.

It is just too big a difference for me not ot look into it.

 

Wow. Kinda getting a bit defensive arent ya? Yes, my comments were based on what I have read. Seemed to me that there were certain themes among people getting the high mileage. That led me to the conclusion that it was possible. It seems that driving style, locations and terrain, and car setup can swing the mileage by 5 mpg or so. Doesnt seem too hard of a concept to grasp. I pick mine up tomorrow. After I buy one, then may I have your permission to read this forum and make observations

 

Look, I value your opinion based on your direct experience. Please re read who said what, in the name of accuracy, .

It's ok I'm not competing with you or anybody. It's ok, really.

If you want to use soundbytes and misquotes......... maybe politics?

Just kidding sir, no ax to grind here, I assure you.

 

Oops. Thought you wrote that. Wasnt a misquote. Obviously just a mistake. My apologies...

Back to the topic of MPG... I am getting a 5 speed and going to commute in it. 40 miles each way, flat ground, sea level, no traffic, I drive 65. First oil change will see synthetics in the engine and possibly the trans. Should be a pretty good test of what the max MPG this thing can get. I will report my findings.

 

Thought I'd add my MPG to the mix. New xD owner and have tracked three fill ups so far. Each time a mix of around 60/40 hwy/city. The first tankful was on the dealer and I have no idea what Station was used for the fill up. I have an automatic and drove pretty conservatively the first three tanks.

1st fill up: 27.5 mpg
2nd fill up: 31.3 mpg
3rd fill up: 31.4 mpg

I might add that I've used Chevron exclusively after the first fill. I also noticed the last avg MPG readout read 33.8 mpg before filling (off by 2.4 mpg actual).

Now I'm driving a bit more aggressively and the avg MPG readout is actually reading a little higher than this time on previous tanks. We'll see how it goes as I get more miles on it.

EDITED to add: Have run the air conditioner from day 1.

 

Cool. I wonder, do you guys have ethanol mandated by your state added to you gas?

In CT its up to 10%.

When I came home from maine I went the same speed as I went on the way up, except this time I didn't stop.

The gas was w/o ethanol and I got the 34. something. The sticker says 27-33, so I have no gripe.

I come in here and read all these 40 something #'s and I'm thinking, how the ****

are they doing this.

I had a 92 civic that got 50mpg when I moved to Wisconsin back in 95' (no MTBE) MTBE used to be in the gas here.

I know I'm not slamming the thing thats what weirds me out about this.

I'm going to baby it for a whole tank, with minimal airconditioning and see what it yields.

I have a feeling it won't change much, we'll see. In a way I'm glad others are having similar milage to me and that it's in the range quoted on the sticker.

Anyway, I hope you all get the high milage versions, there seems to be some out there.

 

anyone know which gas stations do NOT use ethanol? Every pump I go to has a note on it that it contains ethanol.

 

I'm in CT and they all use it here

It maybe mandated in RI, i really don't know. If I could use a ststion w/o it,

I most certainly would.

you will be surprisedc how much paying attention to gas mileage will affect it. I have changed my driving habits. With a manual (which these techniques work much better with) i accel slowly and keep the engine between 2k and 3k rpms. My car is a turbo so i stay off boost. I use downhill to gain speed when possible and let myself get below the speed limit coming up hill. I also turn off the AC compressor when accelerating and i coast in neutral when possible. I occasionally turn the engine off at a long light. Also overinflate the tires. All that and my commute mpg went from 20.5 to over 26 in my WRX. give that stuff a try and let me know what you get in ght xD

 

After a little research, here is a map where all the crappy gas is mandatory:
http://www.mobil.com/USA-English/GFM...soline_Map.pdf

looks like the Northeast Corridor is $crewed...

 

Ok sounds resonable. I always thought that this car would be like the corolla in mpg's but somebody said the gearing is different so thats why the milage is not up to the corollas.

I can do all the things you mentioned. If I obtain those results, I will be in the 36-37
range. So if some are truely getting 40+ mpg, then it must come down to fuel composition or???. If its the 18's then I will see. In the winter I am going to run

some 15's for the snow
