Ford F-150 5.0 Fuel savers
 

I have tried platinum, turbonator, magnets and also fuel concepts. I have absolutely no improvement in fuel economy. Can anyone tell me if they have tried halo spark plugs, or any product that would improve mileage? I consistently get 12 miles/gallon in town and 14 on highway. It is 4 x4 with 5 speed manual.
I need help to decide what to try next.

Possibly a taller, skinnier highway tire to give you a taller gear ratio end result.

Pull out the front driveshaft until you absolutely need 4WD...if it is a slip yoke and won't leak.

Synthetic Fluids.

Get out any extra weight...even the spare...carry a plug kit for flats.

Can you start out in 2nd gear instead of first...that helps sometimes.

Tonneau cover for the bed for better airflow.

Drive slow in top gear. Don't waste energy giving it gas then slamming on the brakes. Etc...

Check out the new members thread (in my sig). You can choose to either modify your truck, and/or drive efficiently.

Best FE to ya...

Welcome!

Look around the site and you'll find a wealth of fuel saving information here!

Change the driver :thumbup:

You said it! :confused:

Anyways, magic-pill type stuff rarely works if you look at the links that I recommended. Driving style and time-tested mods should improve that percentage.

Ford 5.0, now thats a classic engine. How many miles on it? What year? Any trouble codes? Have it scanned for hidden ones that don't actually throw the light.

Check the distributer timing and maybe bump 2 degrees
Sparks plugs (most on here will suggest OEM)
Check your plug wires with an ohm meter , they should be less 1000-3000 ohm's per foot.
Is the EGR dirty?
Is the PCV working?
What shape are the cats?
How is the alignment?
Are the brakes dragging? Jack it up and spin the wheels.
How are the wheel bearings? (I strongly suspect that given the fine tolerances involved that cheap bearings could be more inefficient)
What tire are you running? A highway radial would be best something that allows around 50lbs pressure or better.

Unless you want to go nuts with aerodynamic mods, the driver is the number one place to start.

scandiamn,

What driving techniques do you use or try? What is your trucks epa rating? Is your truck stock? Where do you do most of your driving, highway, country roads, city?

Give us some background and we can help you out better.

I have to totally concur with this assessment. I finally got rid of my problem by giving the truck to my brother. The one I had was built with Ford Quality Control. Somehow and I don't know how, the one I had got 12 mpg, empty, loaded, hot, cold and any other variable you could name. Somehow Ford created a vehicle that just was going to get 12 mpg. Only solutions, really, were to park it or get rid of it. Getting rid of it was cheaper, so now it's gone.

Let's say you average 13mpg combined and you drive 24,000 miles a year with $3.00 gallon fuel cost. If you could find an "EconoBox" that gets 32mpg combined...here is the math.

(24,000/13)*$3=$5,538

Now say you can do 1/2 the miles in an "econobox" that gets 32mpg combined.

(12,000/13)*$3=$2769 & (12,000/32)*$3=$1125

So you could spend let's see...$5,538-($2,769+$1,125)=$1,644

Sounds like the 96 Bronco I used to have...had the 5.8 and around town it got somewhere from 13.5 to 14.5 mpg...feather throttle or lead foot...and it got 16 on the highway, no matter the speed...something about the brick-like aerodynamics of the beast...well...and the mud tires...and the weight...and...and... :D ;)
