Highway MPG

[Project84]

My '94 Camaro Z28 (LT1 6speed) does have some mods, computer tuning, full exhaust, bigger throttle body, deleted emissions equipment, and 160* Thermostat, but it was only able to achieve 23.x mpg on a 250 mile trip to Cleveland last summer. Granted, it was 95*F outside and I used cruise control nearly the entire way going 73mph, but I doubt even w/ extreme hypermiling you could put average LT1 cars into the 30's range consistantly. The cars just literally gulp fuel.
