Fuel Mileage

[bfoot17]

I'm new to this site and look for some help with fuel mileage. I have and 06 250 4x4 thats getting 16 unload and pulling 10 if i'm lucky. No mods yet but looking. Would like to gain at least 4 mpg if possable.

Thanks

Areas that helped me:
#1 - (NO DOUBT) - driving style, habits, highway speed, slow take-offs, coasting stops, etc.
#2 - MINIMIZE IDLING (I still do SOME on VERY cold mornings and days). This helps in a lot of areas!
#3 - tire pressure (go to max tire rating)
#4 - fuel additives and synthetic oil (MY OPINION HERE, many feel differently)
#5 - I got the most recent flash - I LOVE it!
#6 - (Soon to come) I was recently talked into a power elbow for a promised 0.2 mpg improvement.

Other things said to help
#1 - Smaller, lighter, narrower tires - definite help
#2 - Tonneau cover - definite help
#3 - tuner - probably will help
#4 - open up the exhaust - probably will help but is a "high dollar per improvement gained" mod in my opinion.
#5 - Zoodad - probably not much help, but easy

tonneau cover WONT help.....itll get you WORSE mileage. check mythbusters
search for the fuel additive write up on here... it shows which brands do what.
(although in IMO fuel additives is a max gain of .2-.5 gain...)

I get almost 1mpg when i have my cover closed then when its open.

Toneu cover shouldn't hurt, but i'd only expect 0-1mpg.

The MythBusters I saw was on the tailgate up or down. I didn't know that they did one on the Tonneau Cover. Almost everyone I know that has one has said it helps up to 1 mpg ???

Ideally, you'd want to draw a line from the back of cab to the top of tailgate. and then kinda turn that into a topper. That would be you're best "aero" setup. I tried no tail gate and didn't see any gains, probly hurt me if any b/c of the sudden drop behind the cab. I'd say best MPG setup would be a toneou cover. plus it keeps crap out of it.

Funny, Ford says in the owners manual for my 03 Lightning to install the cover when possible to save fuel. I just put a cai on my 06 f250 and the 4'' exhaust goes on Friday. I'm not sure what they will do for mileage but it can't hurt.

[JBakerFX4]

exactly. If I don't sell my Beast I'll be doing a cheapo tonoue cover for convieniance and MPG (if any), but it won't hurt MPG's!! and your owners manual pretty much case closed this thread.

COVER WILL NOT PRODUCE FUEL GAIN, JUST THE OPPOSITE. OPEN BED W/TAILGATE UP IS BEST WAY TO SAVE ON FUEL. REASON? SIMPLE AERO`S, COVER ON OR TAILGATE DOWN OR REMOVED CREATES A DOWN DRAFT WHICH EQUATES TO DRAG THEREBY USING MORE FUEL BECAUSE THE ENGINE IS WORKING A LOT HARDER. TAILGATE UP CREATES A VORTEX AND ELIMINATES THE DOWNDRAFT THEREBY CAUSING THE ENGINE TO WORK LESS AND ADDS FUEL MILAGE.
