What is the normal fuel milage for 1989 SC? Mine is a 5-speed with factory 2:73 gears. Only modifications are a CAI and a intercooler fan.
I was getting around 20 MPG which I thought was not too bad for a V6 in a big car. Last week I pulled the blower to change a worn out snout coupler and noticed the EGR was loose and I had some bad vaccum lines and some were loosely connected. I mades ure the EGR was tightened down properly and put hose clamps on every hose when I put it back together and also bypassed the coolant line to the throttle body.
I just filled up and check my milage and it came out to 25.2. Im going to double check again next tank to make sure my math was right. I knew the EGR and bad vaccum lines had to have been hurting it some but didnt think I would pick up 5 MPGs from it. Anything I might be able to do to pick up a few more MPGs?
What is everyone else getting for MPGs?
