Cant figure out my bad gas mileage!!??
My last fill-up I averaged 12.84mpg with mostly city driving. Damn near everything is new. The engine has about 6K on it so it should be broke in by now. The trans has about 3K on it. I do have the lower gears, but it wasnt that big of a drop. I started with 3.06 and went to a 3.33. The engine was completely rebuilt and runs real strong. It has a new cat, O2, K&N, Syn. oil. It has a custom chip which corrected the trans shift points so it goes into OD and TCC lockup correctly. I turn about 1900 rpm @ 60mph. It doesnt seem to matter how I drive, my mileage stays about the same. I was getting about 16 mpg on the highway. Any ideas???
