9-11 mpg. 3.55's.

 

My last tank was 7mpg, but that tank consisted entirely of trips about 2-5 miles long. I would hope it's a little better when I do some highway driving too.

 

i have a 98 2500 with a 8in. lift and 37 in tires and im asking if anyone knows how to raise the gas mileage of the truck with out taking out the lift and tires because im getting like 8-10 miles a gallon highway...

 

Pretty much isn't anything you can do. 8" lifts and 37" tires aren't exactly fuel efficient. Price to play.

 

That's really not too bad for a v10 truck... My dads '99 V10 didn't do much better than that stock.

 

Worrying about a V10's gas mileage is like buying a hooker and only holding her hand.

You pay money for each to perform a specific function, and expecting anything otherwise is foolish.

 

yeah they bought a v10 to perform a specific function: get rid of all that pesky extra gasoline in the tank with a quickness!

don't really see any other purpose to the V10... definitely ain't for towing power, cause you would have bought a diesel for that if you wanted efficient towing

 

Driving around in a V10 is just cool. Everywhere you turn there's a diesel, V10s seem a bit harder to find...

However, if I could choose, I'd buy diesel. Nothing like the sweet smell of diesel!

 

V10 will tow just as good as a diesel, just gotta be able to afford the fuel. Less noisy, less costly maintenance, all around a blast to drive
