I have a 2003 Ford F250 4wd with an automatic transmission and 3:73 gears. It has low mileage and I want to keep it. How can I improve the gas mileage? I have researched the following modifications on the internet: 1. Cut a hole in the panel in front of the air intake on the air filter. (F…

None of that will make any noticable difference. You’ll either need to drive downhill all the time or get a far smaller vehicle if you’re only carrying around your own carcass normally. That vehicle would already be increasing mileage here in New England because of the rust-induced weight loss pro…

1- no, more likely to hurt mpg and/or driveability. You are not an engineer, and the intake was designed by an engineer with sophisticated computer models and tested. 2- no, K&N filter is expensive. An over oiled filter can restrict air flow. So there is a risk you might not handle the filter pr…

None of these modifications will make any noticeable difference. The folks who designed your truck have already maxed out the gas mileage, and if any of these tactics made a difference, they would already be done from the factory. That V10 does sound nice with a free flowing muffler, though, which…

You’ll NEVER recoop the money you pay for those devices with the MARGINAL increase in gas mileage (if any) you’ll get.

Unfortunately, your vehicle was designed from the ground up for power, not fuel economy. Trying to make it fuel efficient would mean a total redesign with new priorities. Perhaps its time to look for a fuel efficient beater you can drive when you don’t need all that power.

While you’ll read otherwise (mostly on sites selling the devices, or folks justifying their purchases) the comments above are correct. What I get the the biggest kick out of are the ‘throttle body spacer’ folks. For these to work one has to assume the engine designers are, basically, idiots. If O…

That sounds like a 8-10 MPG vehicle, 12 on it’s best day…If you NEED that kind of a vehicle, fine, feed the animal…If you don’t need it, get rid of it…

What you need to do is buy a second vehicle to take the load and miles off of your precious truck. Lets say that your truck gets 12 mpg on your normal commute to and from work, which is 55 miles each day. With a 5 day work week, and 50 weeks you have to drive to work every year, you have traveled 1…

You’d be miles ahead by just buying a smaller car and keeping the truck for when you actually need it.

The most effective thing to improve gas mileage (in my experience) is to drive gently, and slow down. Not only will you be safer, but your mpg will increase considerably. Just driving 65 mph instead of 80mph will save you a considerable amount of gas, will induce less engine stress, and keep you safer.
