Increase Fuel Mileage

Just kinda did another mileage check. I added some air to my tires and drove more on the freeway with this tank, and got just short of 16mpg. The tires were at 31lbs by my gauge and I raised them to about 35 1/2 lbs.
I think that changing my air filter might help too. The truck has only 12,600 miles on it and I looked at it and it was looking dirty.
Is 12,600 to soon to switch to Synthetic.

oil change
I changed the oil and oil filter this last weekend to M1 products. The air filter was changed also. It sounds better already. Want to check the mileage again to see if it has changed or not.

With me changing to RP, I noticed the truck ran alot better. I have 31,000 miles on my 04 fx4. I am getting ready to change my rear diff lube and the transmission fluid to RP. I will admit it is a little pricey but I am hoping that it will help with reducing the friction even more. I have also done an Airraid CAI and I have noticed a difference in the whole truck. I might have to see about getting the truck tuned also to accomodate the CAI. Oh yeah I have a flowmaster dual exhaust also. Any other suggestions would be great!!

I have RP in every fluid holding resevoir with the exception of the fuel tank and the wiper tank. 2006 5.4L averages 18.4 mpg hwy/city mix- so long as I keep my size 12 off the floorboard... and yes I have the mileage/gas receipts to back it up.

The cover will not make a difference one way or another. Here is the physics behind it - trust me I'm a mechanical engineer. Yes, the cover may make your car more aerodynamic - it seals a vacuum, which reduces back pressure and would theoretically produce a mileage spike, but due to the weight increases of an efficient fiberglass or steel cover, some common construction materials for covers on the market today, the result is negligible and could go either way. The reason to sport a cover, like many truck owners do, is not for a mileage spike or some bogus performance kick, it is for a security and storage upgrade. Excuse my long windedness this is my area of expertise.
