I want to make my truck more "gas" friendly, I am not a 4 wheel junkie or a street speed junkie, just want my truck to look good and run well. So with this in mind, what can I do to increase MPG?

I have a 93 F150 XLT Ext. Cab, 5 speed (4 w/OD), 4X4, 5.0L truck.

What Gear (rear) ratio, and engine mods will help increase MPG?

It has AC, but I do not use it, it burns too much gas running the AC. I drive about 65 miles round trip to work, and about 400 miles round trip to another one of my offices. So, at 15 MPG, it can get quite pricey to drive the truck.


Thanks,

Justin

 

I've been looking into trying to accomplih this also with my 4.9L

Heard good results on cat back systems such as Gibson, and also a Throttle Body Spacer such as Poweraid.

 

One thing to do to gain the most out of your vehicle is routine maintainence. For instance:

Tire Pressure: Make sure all the tires are properly inflated

Air Filter: Changed accordingly

Fuel Filter: Changed accordingly

Spark Plugs and wires

A desent brand Fuel Injector cleaner used every other tank full or so

Make sure you drive economically

And, I'm sure there are some over the counter mods you can buy that may help to slightly improve your MPG's. I have a '88 F-150, 5 Spd., 3.55's, 5.0 that I can get 20 MPG country driving and about 16 city driving. And, on a road trip to Drummond Island, my father got 22 MPG.

 

I did just wax it, I figure it will slip thru the air much faster offering less friction and thus saving gas....

 

Give us a hint, what rear axle ratio are you running now?

Ford didn't leave a lot of MPG on the table given the CAFE requirements and 15 MPG is not all that bad for a 4x4. My 96 short bed standard cab 300/E4OD 4x2 is about as light as an F150 can get and with 3.08 gears it delivered 19 MPG highway at 70 in cruise.

 

As stated above, make sure all the tune up stuff is in top notch shape, as well as keeping an eye on tire pressure.

My 302 got a healthy mpg boost from my ignition. On a '95 Supercab 4x4 with auto, I was lucky to break 13 around town. With the ignition it is rare I go below 15 now. On the highway mileage went up some, but not as much in terms of percentage.

My pulleys helped very slightly (about .4-.5 mpg). I installed my exhaust last but didn't really notice any mpg gain, but by that time my mpg was up well over stock.


Do the math on your mileage. Since you put in lots of miles fuel savings mods can pay for themselves fairly quickly.
