I would give my left *^% for 18 to 19 mpg lol (not really) .... Had the Heads done on my 91 Pu 3.slow 4X4 and getting constantly 13 to 14 mpg...

Have not gone through all the other fluids or checked the O2 yet ... but will do that in the next few weeks... Plus Colorado winter gas does not help either.

I went from a car type tire 235/75x15 (29") in my reg cab 4WD, TO a 30/10.50x15 BFG and INSTANTLY lost 100 miles to a tank...

Went from 100 miles PER 1/4 tank mark, to 75!

Keep the ideas coming guys!
