What's MPG? Lol (read topic)

[Monster_454]

My 2000 GMC K2500 7.4l gasser is currently getting close to 7MPG. It has a 3" body lift with 33"All Terrain tires. If driven properly and efficiently, I get about 109-110 miles on one tank. I knew the lift and tires would affect it some, but had no idea it would be this bad. How can I gain a couple more miles on a tank? Thanks

Being it's a 454...I don't think there is much aside from a tune that only "may" get you a couple more miles per tank. Sorry.

Here's 3 things to get you better mpg's:

 

- Ditch the lift

- Ditch the 33's

- Replace the motor with a small block V8

 

 

Haha, you won't get any better mileage with that setup! I bet it looks mean though. Buy a separate car for daily driving....mine gets close to 30mpg's....

Only drive downhill?
