He said GM engines are built loose and are designed to burn a little oil when you start getting a lot of mileage on them. He said its. It not a negative on the engine. German engines are also designed to burn a little oil.

I was told by a master Toyota mechanic that the engine doesn't break in (everything doesn't seat) until 30,000 miles and that your gas mileage will improve a little after that.

Mine (4wd) gets about 14-15 on highway and 13-14 in city. That's the only draw back to the 5.7 v8. Horrible gas mileage. The 4.6 v8 is a nice engine also. Buddy has one in 4wd. It's a torguey engine also.
