Latest Reports:

1. Replaced Oil Cooler Lines and Oil Cooler. (Not F.E. related.)

2. Installed Amsoil Universal Dual Bypass Oil Filtration System - still need to stop small leaks. (May increase F.E. slightly as it significantly decreases contaminants in engine oil.)

3. Overtreated with Fuel Additives Opti-Lube Boost and Opti-Lube XL in at this last fill. Too early to tell how the vehicle reacts or if it increases F.E.; although the vehicle sounds quieter I'm not sure why, maybe the additives help or it's a combination of the filtration and additives.

4. Air Dam isn't on the vehicle, I need to modify it; It should turn around the bumper's corners and not be so flimsily attached to the bumper.

5. Drilled vent holes in fuel cap. (May not effect F.E. but should help the lift pump.)
