Last time I checked the '88 rcsb 5.7 700r4 I got 23.5mpg on a road trip. It beats me that some trucks with similar drive train that are 20 years newer don't get that mileage.

Mine gets around that which blows me away. I can make a 200+ mile road trip and still have between a quarter and half a tank

I average 11.5 mpgs with a mixed 80% city and 20% highway

5.7, 4L60E, 3.73s, 35s, and a Black Bear tune

Averaging 14.5 I'd say its about 70/30 Highway/City Did see 15.4 on my last tank though.

4.3/NV3500/3.73/285s
