I might be buying a 1999 f350 7.3 powerstroke. It has a 8" lift with 42" mud tires, chipped, programmer, after market turbo, HD front bumper. It's 4x4with 193xxx km on it. The guy says he gets 600-800 miles on a single tank on highway when programmed on pulling. How many MPG is it really?

 

It's also supercrew/ extended cab

 

about 17 if it's a long bed and 21.5 if it's a short bed

 

Thanks man. Ill be driving about 1500 km to drive it back how much you think I'll be spending on duel?

 

depends on fuel prices where you're at but it will use about 1.75 tank of fuel

 

How big is the tank?

 

is it a Long or short bed

 

My 02 short bed have a 26 gallon tank, two wheel drive supercab auto would get 20 at best on hi way. I have a buddy with a similar setup to what you are looking at and it gets about 14 on the hi way with 37s.

 

its probably got a 31gal tank, or maybe a 29gal

 

So basically on highway I could be looking at 20-25 mpg on highway in tow mode? That's if this guy is telling truth about the 600-800 per tank.
