Not a terrible engine. Biggest problems they had was burning oil and leaking oil from the rear timing cover. Chevrolet says that 1qt every 1000 miles is normal consumption. My problem is that no amount of cosumption is normal in a properly broken in gas engine below 75k miles.

18-20??? Really??? I have a 2002 extended cab and around town I'm lucky to get 12 mpg. On roadtrips I can expect 16 mpg's. Is it because mine is an older motor, it has 114k on it. But it runs great and I haven't noticed a bunch of oil burning. -Stew-

My buddy has a 6.0 in his '04 extended cab. Custom ground Comp Cam, long tube headers, Procharger and few other things and he gets about 15-17 in town.
