Okay, I'm utterly confused at this point...
My truck gets about 16mpg. I think that this is awful, and I'm trying to improve it. So I started with the grille block. The last tank I ran (It wasn't full, just $20 worth) but I went from 16mpg to 13.06.
What?
I'm really sensitive with this truck; it's my baby. I'm really ginger on the gas, I pop it in neutral at the stop lights... How am I losing gas mileage?
Any ideas on Aero mods or "Adjusting the nut behind the wheel" are greatly appreciated.
Thanks everybody!
