It's a 92 cougar with the V6 3.8 motor unfortunately not supercharged. I had to rebuild the top end due to a head gasket failure. She runs good and I usually average around 18 to 20 MPG. not to bad for a 92 that weighs nearly 2 ton.
No current mods for MPG's yet. I have put in a sound system wich if anyting will decrease my MPG by a samll amount.
I would like to hook up some sort of display of engine parametres and mileage.
