Back when gas prices were $4+ last summer and I was driving a 100 mile roundtrip commute to work, I drove like a grandma (Crusing at 65-70) and regularly saw 30-31 MPG with an automatic 2000 2.5RS.

Now that gas prices are down I drive 75-80 and still get 27+

30 MPG? thats great! I get 25 MPG the most on mine in freeways (driving @ 65-75 MPH) and about 21 MPG on streets. one full tank on mine ranges about 275-320 (mixed freeways/streets).

In the time I owned my RS I ran out of gas 4 times in the first 3 years. Every time it was in the mountains with steep climbs involved and every time once I got filled up it suggested there had been a gallon or more sitting in the tank out of reach of the fuel pickup.

thats what i get too. i've been trying to get my average up to 27 mpg, but i can't do it. i always average 23-24 a tank. i guess the hills don't help with mpg...but i wish i saw 400+ miles on tank in my car

I have yet to run a full tank on the highway. Between Denver and Colorado Springs and back, I'll use less than a 1/4 tank if I cruise the entire time at about 75.

We'll see how my little 1.8 side project does with some fuel chemistry work. I have yet to push 40mpg on a high ethanol blend in a Subaru, but that's next. 1.8's with a good tune can get 34mpg on straight gas. 32mpg with no fuel voodoo is an achievement to me in my RS on E85. It's like running fast on wastegate boost...but...not .

How many of you see 400 out of that little 11 gallon tank with a 1.8? That's my goal.

I got a very good bit over 400, maybe even 450 (I can't really remember) cruise controlling down to TOTD going about 65 the whole way. I think it was something like 32mpg at least.

The best I have ever had was 33.2mpg in my legacy N/A. That was going 55, and then 65. cruise control was on and I never slammed on the gas to get on to the highway. My computer said I was getting 35.5mpg. but 33.2 is damn good for a full time AWD car.

i've never ran the tank to near-dry but i've run over 340 miles on 3/4 of a tank, calculated from filling up. done a couple 33 mpg runs as well from filling the car up from 1/4 tank full.

my general rule is driving normally i see at least 100 miles per quarter tank. if i'm driving hard i usually see 24-25 mpg.

I regularly get 28-32 mpg (and regularly got ~30 in the '02) through the mountains in new york. When i ran it dry it was through the hills in pennsylvania.

I get about 30 with a fully loaded, saggy ass car through the same new york hills.


It's not the terrain, you just need to learn to drive.




EDIT: also, turn off cruise control if you have it.

Is this really common? I started searching for threads about the fuel pick up and running out of gas since I almost did the other day.

I normally get just over 26MPG and with the tank listed as 15.9 gallons I figured I was in a safe range. The fuel light came on just as I was leaving work with a 30 mile commute. As I neared my exit on the expressway at about 70-75mph the car started to hitch and miss, a quick left right of the wheel would fix it for a few moments. once I was at city speeds I had no problem. when I filled up it only took 14.2 gallons. guess I need to treat the low fuel light as a 'go fill up now!' light.

there must be a difference in Tank size then between the RS and 2.5i. When I lived in AZ with my RS for years, I never got close to 400+ miles but consistently got between 29.xx and 3o.xxmpg which I found was REALLY good for the RS. Because when I moved to San Diego, it went down to about 26. Which is also what I get on my New 2.0T 24- 26 hitting boost quite often with a lead foot. but with 91 vs 87

Well, I haven't taken the headers off yet - too busy with fixing this rough idle I had. The whole underside setup - exhaust, driveshaft, etc. is coming off soon so I can redo the undercoating, change some bushings and hoses, and clean the thing, I may do it then.

I usually average 29-30 MPG combined on my 200k mile 2.5RS. Two times I can remember cracking 400 miles on a tank. I also live close to 9000 feet above sea level, so that puts a hurting on my mileage. When I take it to the track it drops to around 23-24 MPG.

Williaty, was this with a custom tune. I've heard you are the NA tuning master and I'm just curious, were you running a self-made economy map? That is very impressive!

On our cars, the "custom economy map" is flashed into your right foot.

I get about 250 per tank fill on my 2.2, which has drastically gone upsome how from an awful 180 range... weird too, because stock I got about 180-190, and now with header and a catless exhaust, I get more hehe, weird.
