I just receintly purchased a chevy S10 4x4. very rarely do i see myself needing the 4 wheel drive, but i got the truck anyways due to the well spoke of 4.3L V6 vortec engine and all of the other features this 2004 truck comes with. i wanted to put a carbon fiber hood and body kit on it with slightly larger rims and low profile tires. at the same time i thought i'd lower the truck a couple inches (my friend is telling me not to). this thing gets about 19 mpg as is.. by doing as described above.. what will that do to the gas milage?
