Hi, I just joined here today. I am looking for ways to improve on mileage with my vehicles. The main drivers are a 1989 Chevy Celebrity with 3.1 V6 (summer driver), and 1989 Pontiac 6000 wagon with 2.8 V6 (winter driver). Id appreciate any tips on modding for mileage on these engines. Both have 4 speed automatics with 3.33 final drive.

I have already done the easy stuff... take it easy, keep speed under 65 on the freeway, keep it in OD whenever possible, etc. Best I can get is 28 on 6000 and 32 on the Celebrity. BTW the 3.1 engine used to be a 2.8, when the head gasket blew I put in the 3.1 instead and gained torque and 2-3 better mpg.

Right now I have 195 tires on them. I have a set of 185s in storage that still look good, I am thinking about trying those on the Celebrity.

I also have a 1992 Pontiac Trans Sport with 3800, which I dont drive too much since it is a gas hog, any tips for that would be appreciated as well.
