I'm not intrested on what the manufacturer "states" about there product,
I'd like to hear from you guys that have actually seen improvement.

Thanks

I installed a Flexlite 250 electric fan; minimally, it was good for 1.1 mpg.

I installed all at once: Accel coils, Jacobs plug wires and Bosch copper plugs gapped at .70"; and then Jacobs DIS. These additions were good for 1.81 mpg, however, I can't tell you if it was just the Accel, just the DIS, or the combination of both Accel and Jacobs that yielded the mpg, because I didn't mileage-test them separately. Accel coils and Jacobs plug wires w/ the Bosch's were good for ~4-5% HP and torque seat-of-pants gain.

I've installed Flowmaster 40's (as dual), MAF, TB, and K&N kit. No noticable mileage gains from these products.

A tonneau cover will increase gas mileage at highway speeds.

 

You could try "installing" yourself into a Focus.

Actually, driving habits will have the most influence on your economy. Just take it slow and easy.

 

The electric fan is the only mod I can think of that is a definite.
I'm am seriously considering doing this mod.
It seems VERY logical on how it increases MPGs by ruding engine drag.

 

nomo lol thats to funny!

 

Well, I have to disagree with Nomo. I can drive my truck easy for a tank then hard for a tank and I'll get 13.8 to 14 mpg either way. The only time I do worse is pulling a boat when it drop to 11~12. I have given up trying to drive it easy. It's boring, takes thought while you are driving and doesn't do squat for me. I am also seriously considering an electric fan.

Jacobs ignition, coil, wires good for a little over 15% mileage on my 302. Underdrive pulley set picked up close to .5 mpg.
I've never noticed any mileage increase from intake or exhaust mods.
Both of my last two trucks had tonneau covers, very slight increase when on the highway.

 

My experience has been this:

1) I have tracked 1-3 MPG increses when switching to synthetic oil only. I have tracked 1-2 MPG increases when switching to synthetic in transmission and transaxle. However, with the extra power available 5-8hp it is easy to get a heavier foot that negates these benefits.

2) I have tracked 1 MPG with a foam/oil air filter.

3) I have tracked a 1-2 MPG increase while using Amsoils' PI vs. not using PI with same fuel type and station.

4) Other items to consider: Proper maintenance is a must, as gasoline engines are always on the decline with performance. things like O2 sensors, thermostats, plugs etc can rob you of efficiency.

5) Keeping tires at or slightly above posted air pressure for the load, and keeping the alignment up to speed.

These things can increase your mileage, however they can only do so much and at some point you will hit the engineering limit for the equipment that your vehicle has.

Actually
The dealership "installed" me in a Focus while my '99 P.O.S. Ranger with 20K miles on the was getting the heads replaced. Thats a pretty fun car, (if that's where your at).
Well I'm in a '97 F-150 4x4 now. This has a direct correlation to how well the head job went. Along with the rear pinion, Paint finish, Wiper switch Power steering Pump ..............

 

Where is some proof that a bed cover helps with mileage, I beleive thats a wives tale. At any speed that air hitting the tailgate would cause drag, that same air would be deflected beyond the tailgate. I have had trucks with covers and shells, on or off I could get a measureable difference. I found that if I punch my truck a few times on a tank that it makes more difference then anything like a bed cover or a camper shell on gas mileage. Consumer reports couldnt see a difference either.

 

I can get the best milage out of my F150. I hook my Jetta TDI up to it and pull it around, since the jetta gets between 47-53 mpg, I figure pulling the truck would still net me at least 35mpg!! HAHA.

All kidding aside just filled the truck up today with 23 gallons of midgrade at 1.43/gal. I went 330 miles on the last tank for a grand total of 14.3 miles per gallon.

I don't know what to tell you all about getting better milage, but if you can keep it on the highway and out of the city that seems to help the best, cause even driving 75 I usually get 16-17. This last tank was all in town driving.

Randy: You are the only person i know of, besides myself, who uses Amsoil PI. My experience with it is this: The more exact you can be measuring it before you put it in your tank, the better the results will be. I use a small measuring bottle. Experimenting is the order of the day here. Because, lines on bottle may not indicate a true oz of PI. Please e-mail me on this subject to: sundayniagara@hotmail.com, or doorslammer69@email.msn.com!...Thanks Mark

 

What is Amisol PI?
{Pardon my stupidity}

 

Hmmm, how to get better mileage...

How about a 4.6 with 3:08's, 2wd, and 235/70 16 tires?

Well, since that probably isn't your first choice, contrary to other reports here, I did notice a mileage increase with a bed cap. I went from maximums of 19 to 20 mpg, doing 70, for 600 mile round trips, to 22-23 mpg on the same trip, with the only change being the cap.
