I usually fill at around 1/4 tank remaining, and the most miles I have gotten to date is around 190, and that was with a good bit of highway driving. On average I get around 160 miles per fill.

I'm getting about 20mpg on my daily commute which is 50 miles roundtrip on a hilly and curvy 2 lane highway. I just went on a roadtrip this weekend to VA and got about 22 on PA's crappy I-81. That was driving several times at a crawl and idling in clogged construction areas. On the way home there was less taffic so I could use cruise more. I got 25.5 on that tank. I've never got less than 260 miles per tank. The car is 1 month old and now has 2k miles on it,

Welll.... if you go on a long trip, you gonna tac it out the whole way? Now a vette gets around 30 mpg cruising all day above 80 mph.. interstate miles. Nothing wrong with sucking it up at WOT.. but nothing wrong with getting 30mpg on a long trip either....

Has anyone else gotten better gas mileage on Shell (93). Today I was driving pretty hard on hilly and curvy backroads and I got 24 mpg. That's higher than I get on Mobil driving like a grandpa.

I see about 280-300 miles per tank with normal driving. Includes a few good runs through the gears every day it is driven. Even on my current tank with an autocross it'll be over 270. 5500 miles so far.

Different formulations will have different energy content. Ethanol doesn't have the energy content of gasoline, so ethanol blends typically get slightly lower mileage. (1-3 mpg less in my experience).

so you think that those new shell ads are because shell has started reducing the ethanol in their gasolines?

I have over 4600 miles on mine. range from 13mpg to 23mpg. Boost= lots of fun= lots of gas. Damn I love this car.

Snow should prove interesting, we're supposed to get a ton of snow this year. I'll have to go back home to NY to find some really fun roads.

Gas isn't really that expensive. 100 Octane is only like $4.30 a gallon here, now that's an expensive but really fun treat! Think about everyone else in the world that pays out the ass for gas (although we get crappy oxygenated fuel here near Philly).

Default might have a problem....?????

I think I might have a problem with my car. I am only getting 16 miles per gallon all the time. I doesn't matter if it includes a lot of highway.
Is there any way to turn down the amount of fuel being sent to the engine. Any way to make the car more lean??? and thus get more mileage???
I have read that the car comes very very rich from the factory, and that leaning out the engine a little would not hurt it at all. How would I do this???
I think it is silly wasting excess fuel when you don't have to.
Cheers

Default milage

I'm averaging 275 - 310 per tank - down to low fuel light.

I drive 500 HWY miles weekly, but I jump on it alot. I run 94 Octane for 3 tanks and then drop a tank of 100 in. That is the way I've been driving it from day 1. Synthetic oil....

11158 miles and counting

Maverick1, a couple questions for you...
How did you break your STI in? What tire pressure are you running? (How often do you check? Checking tire pressure is cheap and easy but occasionally overlooked.) Could your alignment be off? What DCCD setting(s) are you running? What shift points are you using? Is your air filter clean? How much throtle pressure do you use when changing velocities? Do you brake late and hard then power out of corners (always) or "coast in, coast out"? How much steering input do you use when traveling a straight course? A 1% steering error (wobbling in lane) results in a 3% increase in rolling resistance. Just some atarters.
My best run in my '02 WRX wagon was Niagra Falls to Sarnia/Port Huron at 30.3 mpg INTO a 30 to 50 mph headwind, keeping up with traffic so as not to be a hazard. Tires and alignment to spec, slow hands on the wheel, and throtle changes like I had a raw egg between my shoe and the accelerator were probably the biggest contributors.
Good luck, hope nothing is wrong with your car.

Damn, I get pretty good gas mileage then. I do about 65% city and the rest highway and when I'm on the highway I have a LEAD foot. Accel., slow down, accel....repeat...

I always get about 18-19mpg. The funny thing is I have driven it real easy and still only managed to get barely 20mpg so I figured I'd drive it hard...

Yep!

I average about 30K a year driving. I put 21K on my WRX in 8 months.

If you are going to own it...DRIVE IT!

I get 12-14 mpg all city. my commute to work is ~3.5 miles and with plenty of lights, traffic, construction. ugh. (that and I am very impatient and when a slow moving person moves out of my way I almost always end up in boost).
I did notice though I got much better mileage when my commute one week was all highway driving.

Default Thanks Fogrider....this is my story

-tire pressures are-36 front and 30 rear.
-I average 85mph on the highway and generally step on it in the city.
-I guess I drive it on boost a lot, but so do others on this forum and they seem to get 275-300mpg, while I only get 180-230mpg, and that's city and highway combined.
-DCCD is usually set to auto.
I only have 2700 miles on the car. Will I gradually get better mileage as I put more miles on the car???
Hopefully my mileage will get better soon.
Cheers

Default something to try

2 more pounds in the rear for "long hauls" or long commutes might lower rolling resistance a bit but to rule out something that might be a SoA issue, you could try NOT going on-boost for one tank of fuel and see if it made any difference. If you saw the same poor mileage, it would be my conjecture that you have a problem that the dealership should evaluate.
Our ECU's "learn" our driving styles to a certain extent and even modern tight-tolerance engine have a break-in period when moving parts bed in. But if you have some problem of fuel delivery, combustion or utilization of generated power, I doubt that would improve from time alone.
Good luck and let us know what you try/find out.

I miss my vette's 30 mpg highway cruise... my STi is averaging 16.5mpg and I'm not even out of break-in! (50% highway and shifting at 3K or less)

How can they advertise 18/24mpg? Does anybody actually get 18 in the city?

on the highway i hit 300 miles, then filled up about 14 gallons, which comes to about 21mpg. but that was with frequent stops and constantly going between 60-80 b/c of break-in. It should do slightly better once i can start using cruise control.

city, i get about 250 (not pushing hard since breaking-in) which is about 17mpg.

Once i'm done with break-in, i'm guessing 200 miles per tank which is about 14mpg.

In order to reach the numbers they advertise, you basically can't enter turbo territory, so if you drive everywhere under 3000rpm then you can probably get that mileage.

I do at most 20% highway for miles on my STi. About 70% of my miles are surface street commuter miles an average of 45 to 50 mhp. The other 10 % of my miles are my fun miles. They are mostly 2nd through 4th between 4000 and 6000 rpms in twisty hilly terrain. At 5058 miles I'm averaging 18.254 mpg at 11.4 cents per mile. This is data since 2430 miles. I lost a receipt. This is better than I expected. But this just means that I'm not putting in enough fun miles. I guess I'll have to work on getting my mpg down .
