i have the 5.7 engine and only get around 13.5 to 14 mpg what doy you guys get mpg??

Well I just baught my 97 5.7L and I am getting just about the same

I bought my 98 new and am getting 20 on the highway and about 16 in town. There were 2 axle ratios 3.42 and I think 4.11 but not sure any more. The Z71 all had the higher ratio. I took the lower one and have never been sorry.
