I was wondering what I might expect to get for fuel consumption with the 5.3 V8 engine. I will be in the market for a replacement for my 98 Silverado in the spring. It's turning 140K and will be looking at 150K by then. Time to replace it even though it runs great and you'd never know it has that many miles...

I was also wondering since the Silverado has a snow plow on it would the plow frame fit a 2006 truck.

Thanks

 

it depends on other thing as well...but a 1/2 ton 2wd 373 rear end gets around 18...21 if really babied

 

If you drive it normal and plow snow then you're probably lookin at about 13 to 17 mpg

 

just bought an 03 gmc 1500 4x4 today
and was wondering the same thing about
gas milage.

thanks
