I got just over 35mpg on an open road trip in the Euro R - 466Miles with A/C on most of the way!! (750km's off 60ltrs of petrol)
Get roughly 31mpg around town driving in it, fairly economical for a 4 door sedan IMO

have your catalytic converter checked out at a muffler shop. I get about 425 on a tank. I just tuned it up with 10mm wires, ngk plugs, new cap n rotor, cold air intake and full magna flow exhaust and headers though. Little things can rob your mileage like dirty air filter, fuel filter etc

I drive 200-300 miles a DAY and can honestly say that when I put these 18x7.5" TE37's it KILLED my mileage.

5 speed, 267k miles (as of today), intake, header, and about 90% hiway driving.

Stock 15" 02 SE wheels:
Average: 400-425 miles on a tank
Least: 323 miles on a tank (lots of idling too)
Max: 563 miles (amazed I made it to the pump!)

18" TE37's on it:
Average: 360 miles.
Low: 292 miles
High: 404 miles.

It's pretty much the same with or without A/C on. The ambient temperature makes a big difference too. 100+ degrees out, my mileage suffers. Extreme cold it suffers too. 60-70 degrees, no A/C and 100% hiway (and on the stock wheels/tires), I bet I could stretch 600 miles on a tank.

...oh yeah, and the E10 (10% Ethanol) kills my mileage too. Generally if I was getting 400 ethanol free, I would get 360 to a tank with ethanol (average).
