gas mileage

[6gunn]

What kind of gas mileage does a stock to slightly modified GN get?

I get about 17 around town and getting on it and about 23 on strictly highway with 3.73 gears and a corrected gear in the trans.

What are your BLMs on the highway?

I've gotten almost 20 in the city, and 26 MPG on the highway. I know a guy who'se getting 600km a tank on the highway!

Dan,
I haven't been driving the car much lately, but I will make sure to take note next time and let you know.

Mixed driving 17 mpg.

Both cars.

20-21 mpg on the highway long trips, tops.

There have been several good threads on this subject on all of the Buick Turbo boards, and I am not going to post my recorded results as I have posted them and the conditions several times. However, bond stock and very minor modified, on 5 different turbo buicks, all '86-'87, only one modified, I have gotten on the average exactly what SalvageV6 stated. My bone stock '02 Z06
gets about 1.6 mpg better under identical conditions, but none of these cars have ever been on a really long trip.
