How To Increase Gas Mileage on 2007 Ford F-150


2007 Ford F-150 Engine Size : 5.4

Question : what can i do to get better gas mileage on my truck. I have a K&N air filter and straight dual exhaust.

Answer: Stick with the basics- keep engine tuned up properly, check tire pressures, do not have unneeded weight in the truck, change your oil regularly etc. Although there are many companies that say their product can increase gas mileage, I have not found any that have conclusive evidence of that. Especially in today's newer cars and truck. The computer system is set to specific parameters to gain the best fuel mileage, power curve and other specifications.

There are companies that re-flash the computer, add sensors, etc. Many times this causes more harm than good. Sometimes you gain a few horsepower, but ruin mileage and can shorten the life of the engine. So do some research and look at all the different claims, and decide for yourself if you want to try one.


Change Wheel Size

I have a 1991 Ford F-150 1/2 Ton stock P/U with 15" wheels, wanting to go to 16", is it possible? If yes, what do I need to do?

Answer: Yes, you can change wheel and tire size. You need to make sure the new tires will not rub on the fenders, especially when you are turning the steering wheel. You will also have to change the speedometer gear in the transmission output speed sensor or the speedometer will not be accurate. This is only need if the combined wheel and tire size is a larger or smaller diameter than the original setup.
