I am posting for my brother.

This past fall he bought a used 2005 RS 2,5 from a used car dealer. I do not know his exact mileage but it is somewhere around 30,000 miles.

He gets only 22 mpg. Is it normal?

I just searched this forum for an hour but nobody talks about MPG here. The only suggestion I found was to use higher octaine. Is it right?

I get 21- 22 mpg in my 2000 RS if I'm just driving around town (very similar motors). My car's got 100k+ miles, and I'm pretty heavy on the gas, but that always seems low to me...

Only on long-haul interstate trips can I up it to around 26 mpg. I think my highest ever was 28.

Octane rating should have no effect on MPG. You'd just be paying more.

Thanks, Jay.

I too think this is quite low. Some people on ultumatesubaru.org reported that kind of mileage, but that was the lowest one.

On my 2.5RS's I used to get up around 30mpg on the interstate.

I get around 32 in the Legacy with cruise control set.

22mpg is low, even for a WRX it would be low.

The SOHC 2.5 with longer gears gets around 30 mpg on the highway, but with the shorter gears of a 2.5 RS, I wouldn't be surprised at 26-28 mpg. :)

I have a 95 Impreza L.

I checked consumer reports and it gets 28/22 MPG highway/city.

If I get a better intake system I'll hopefully get about 30.

If I had a manual, it would get 4+mpg..

60% city %40 highway 1/3rd heavy traffic in highway I get 28MPG average. Used same gas station (HESS). 2005 SAAB 9-2x NA 5 speed. I use neutral a lot, up-shift 2K rpm-2.25k rpm (drop to 1500), 5th gear city driving for locking a speed above 35mph (can't accelerate though). Trick is, lowest pedal at for given speed. In traffic use neutral, keep atleast 2-3 car distance -use that wasted idle power (clutch, no gas). Also in the city, try to hit all the lights, good timing and passing stupid slow illegals in vans is a plus.

My overall average was 27mpg in my old 02 2.5TS, and that was without an o2 sensor which was probably costing me one or two mpg. This was with 160,000 miles. I was pretty light on the throttle though, and I usually managed to not slow down for corners haha.

Try a good tuneup, new filters everywhere, new plugs and wires.
