Ford F150 4.9 MPG increase?

Post #1 by 93FordXL » Sat Jan 01, 2011 11:03 pm

Hey ya'll,
I recently purchased a 93 F150 with a 4.9l. The overall truck was very well taken care of and right now runs very well, but I know there are a few things out there I can do to improve the gas mileage. Does anyone hear have proven methods to increase air flow and/or fuel economy? I'm very familiar with other engines, yet inline 6's are another beast I've yet to master. Any suggestions are greatly appreciated as I'm just beginning to gather as much info about these motors as I can.
Thanks in advance

Low cost is advance ignition, change to all synthetic oils, K&N air filter, after that it gets more expensive, like a better flowing exhaust system and few mods inside the engine.

one of the biggest things you can do is go easy on the throttle. a vacuum gage helps you see how much youre giving it, so you can see the need to pull back a little and save a lot of gas.

regarding the K&N that bubba mentioned, those have been disputed back and forth, and the general consensus from what i've heard is they can't flow any more air without reducing the quality of filtration, and from what i've heard theyre not a good fit for an economy minded user

If you do a search for mpg in this forum you will find lots of suggestions and ideas. A vacuum gauge and adopting hypermiling-type driving habits will get you more bang for very little bucks; my suggestion is you do that before you spend money elsewhere. A tonneau will help.
