I wanted to see what fuel mileage other G20 drivers were getting. I'm getting 20-23mpg with a mix of city/highway.

My 02 Sport Auto, with my wife driving most of the time, consistantly gets 23 in town (95% stop and go on significant hills.)
Add in 100 miles of highway driving and it hits 25-26 MPG.

My best with the AC on last August was 31 MPG.

Thats good. The highest I've gotten was like 26mpg.

Oh, one other thing to consider... I run 89 octane (10% ethanol and cheaper than regular here in Iowa). The car had a new cap, rotor and wires on it when I got it. It could use plugs but have not had the time to do it with school this fall.

I get around 22 mpg in mixed driving. On the highway I get about 28 mpg. I have JWT S3 cams, TopSpeed header and have my timing advanced to 17 degrees. I've been using premium for the longest time and never had any major engine trouble. The car has about 250k+ on it (the odometer is broken so I'm estimating).

Hey Ryte,

are you a P10 or P11?

I can get consistent 29 mpg on my 99 P11. It has a u13 SR20DET with GT28R turbo. I have to be easy on it to get that kind of mileage though, otherwise it's around 25 mpg.

BTW it's for sale, PM me for details :)

My apologies for taking so long to get back to you; I have a 95 (P10).

No worries!

Another thought - I recently did NGK plugs along with a new universal oxygen sensor after getting a SES light showing lean condition. My last tank of combined driving of 200 miles to Madison and 100+ of miles around town netted 29 MPG

Overall, much improved, especially in town.
