Been Lurking a few months............
Hello,
Been lurking for about 6 months after I decided it was time to put a stop to so many trips to the local gas station. Started looking for websites that would guide me to better mileage and ended up here.
While a 1999 F150 with 4.6 engine and automatic trans is certainly not the poster child of elegant fuel economy, one has to start somewhere. Before I came here I had already removed the antenna and was amazed how well the radio worked if I stayed in town. Following is a list of what I have done to transform the truck from stock to a best test drive of 25.5 miles per gallon recently.
Radial tires inflated to max pressure
Royal Purple 5-20W HPS high zinc phosphate oil in crankcase
Royal Purple high performance wheel bearing grease
Royal Purple synthetic gear lube in rear end housing
soft bed cover
Amsoil Nano air filter
Remove jack
Remove spare tire
Remove spare tire lift mechanism
Remove trailer hitch
Remove worn out floor mats
Empty glove compartment and behind seat storage
Partial lower grill block with Duct tape
Coroplast air dam
Aerodynamic wiper blades
I found it amazing how removing the excess weight helped to raise mileage with zero investment.
The more expensive modifications now loom before me. I have considered several options including the items listed below and wonder which ones might result in the best fuel savings per dollar investment?
Electric radiator fan conversion
New low rolling resistant radial tires
Belly pan
Tire spats in front of rear tires
Lithium ion battery
Royal Purple Max ATF in the transmission
With many directions still to go in, I may yet make it to 26 miles per gallon or even better.
