What is your mpg? What size tires? What is your axle ratio, what speed do you drive on the highway, and what transmission do you have?

There are no engine modifications you can make to improve mpg.

You answered just one question, the transmission type. If you want suggestions, you're going to have to provide all of the requested information. "Stock". means nothing since even the factory tire sizes varied. Your axle ratio is either 3.07 or 3.73, look at the tag located at the 9 o'clock position located on either or your axle differential covers. Your axle ratio will be embossed into the tag, which ratio do you have? The tag might also say 3.08 or 3.74 depending on which axle you look at.

Also, exactly how are you measuring your mpg? Are you going by your gas gauge or are you dividing the exact miles driven by the exact gallons consumed? The gauge is notoriously inaccurate and it will show significantly less fuel is in the tank than really exists which wil make you think your mileage is abysmal.

And depending on your answers, the might be a simple fix like a new NTK upstream O2 sensor.

I have a 4" lift 33" tires, 4.56 axle gears, and I get about 10.5 to 11.5 mpg.


Do you have a roof rack, silly light bar, or other accessories to increase drag?
