Default mpg

i have to admit, I am getting less miles per gallon than I would have liked, but in the same vein, I am driving with a little more, uhh, gusto, than before. I always fill up when i have a quarter tank left, and i have usually 200 miles on the tank by then.

I have 1200 miles on mine, and am right around 25 mpg. That includes me being nice during the break in period.

Butt dyno says no faster, but I live in a town that may as well just turn itself into a giant retirement home, I don't get to go fast often =( Maybe that's why my mileage is so high for mostly city driving...

A lot of people on this board reccomended those oils, plus...

I keep an insane amount of data on my cars.

Fun fact: The worst gas tank did NOT occur because of an autocross. I think it was just cheap gas. Actually, my last couple of autcross events have yielded better-than-average MPG.

Hehehe, thats what I get too. Its just so hard to keep the right foot from planting it down when I get behind the wheel. Conversely, my wife when she drives it she gets about 27-30 mpg. I tend to have her take it when she goes long distances, since I trust the Suby with her life more than her Durango.

If I take it easy I can get closer to 20 mpg, but hell who cares! VRoooom.

I keep a lot of data, too so here are all my numbers for the same categories, including estimates for the gas in the car when I bought it and a couple of blurred receipts:

Miles Recorded: 24,069
Total Cost of Fuel: $1,980.21
Total Gallons: 1,258.17
Average Cost per Gallon: $1.64
Average Tank Size: 12.58, which includes about 8% tanks not totally filled, usually because don't have access to 93 octane
Average Days between Fuelings: 3.5
Maximum Days between Fuelings: 10
Average Miles per Gallon: 19.13
Average Distance on 1 Fueling: 240
Maximum Distance on 1 Fueling: 369
Maximum Miles per Gallon: 25.9
Minimum Miles per Gallon: 14.2

Guess that goes to show that it depends how you drive your car.

This is my first 100 fuelings, in two weeks short of a year.

the last couple tanks I only measured about 15 mpg. I do mostly city driving and I probably have a heavy foot by most standards. But I still wish I had better effeciency, something like 25 mpg, like some of you are getting would be nice.

Hey, since everyone's on the topic I was actually having a little problem with my RS. It's got 10000 clicks on it and i'm recordin (this is in Canada so the measurements are different) about 30 litres for every hundred kilometre. That means I get about 200 kilometres on a tanik of gas. My logic may be flawed, but something is definetly wrong? Any ideas on what the problem might be guys? I thought it could be the floater in the tank being inaccurate but it just doesn't seem right.....

Default metric system

IIRC 100 km = 66 miles. If that is true, you are saying you are getting about 130 miles/tank??

Or another way: 66 miles/30 litres =
66 miles/7.9 gallons or 8.4 mpg (!)

I would say something is amiss.

Sorry that my car is not WRX. But I figure it may be useful to compare with the NA 2.5L.
I have a 00 Forester AT around 74K.
I will say I used to get 24mpg.
I drive around 360-380miles before my engine REALLY run out of gas(a few times it happened.
The yellow-orange gas light turn on around 290mile and off again later. Not until 300-310 miles that it will be consistently ON.
All stock(air filter changed). Even the spark plugs are original. :P

Here is the reason I would like to reply to this post.
First, the high speed thing. I think subaru intake air flow design is VERY bad. WRX is a bit better but... More room for improvement.
I think maybe during higher speed, the WRX intake on top of the grill is more effective due to engine compartment temperature.
But the DIY mod to cut the front weather trim will help even more.
"Just a piece of plastic"!!!

Second, I really have to complain about the stock spark plug(Champion). Not just the plug but I am doubtful on the manufacturing gap consistence also. Why do I say that? Well, when I change my plug around 74K(my bad), the 4 plugs gaps are like this: .62, .52, .56, .66.
It made me think if the original manufactured install is not right.
Can someone with a WRX and willing to change their plugs to confirm their plugs gapping? I do highly recommend anyone with the original stock plug change to NGK VPower plugs. I do think it make a difference. The trouble is after the change, I have reset my ECU due to taking out the battery. Plus some CAI and Redline oil changes. So I don't have my current stable data yet until maybe next month.

Sorry for the mumbles to the WRX fans.

I'm on Stage 1 now with a K&N drop in filter and I'm between 24-26. That's without babying the throttle and some freeway traveling. I'd like to try all backroads (mostly 45-55mph zones) to see what the difference is (my Celica GT with I/H/E mods got 40mpg doing that). I've noticed if I go on the freeway my mpg actually drops due to the wind resistance over 70mph.

I'm going with Uppipe and Downpipe mods/stage 2 in about 3-4 weeks and I'm curious to see what that will bring. More to come!
