Default Re: 2003 ford ranger fx4 gas mileage?

I have a 2003 Off Road 4x4 4.0 auto, 4.10 ratio. I bought a K&N look a like air filter kit from E-Bay for 35.00 and a cat back single performance exhaust system for 180.00 E-Bay also. I gained around 5-6 MPG, and a tremendous power increase. When I removed the factory air filter box I was shocked by the small diameter air intake coming into the box, I am going by memory but roughly 1-3/4" ID.

Default Re: 2003 ford ranger fx4 gas mileage?

I have a '05 Step side 4x4 ext cab, with the 4.0, and the auto tranny. I carry a tool box weighting over 200 pounds, only mods are a K&N stock replacement air filter and a 2" lift all the way around. I keep the tires inflated and regular up-keep(oil changes at 3k-3500 miles, all original motorcraft parts, motorcraft fluids) and get 16 mpg in town, and 23 highway, why do I see so many people in these forums with gas mileage that is worse than this?

Also, I have a buddy that changed all his fluids to synthetic and boosted another 2mpg in town and 3mpg highway.
