dont nail it when you take off, dont get up to highway speed in the first 20 feet, drive at a speed where the RPMs are at 1800 or so. speedup on the backsides of hills and dont use the cruise

Im getting 19.9 with my Excursion using these methods.... hand calculated and filling the tank until its full with no foam (which is a pain) lol

Unhook that tractor from the back of your truck j/k. Might give an addative a try some people have luck with it some don't. I have tried a few nothin real sagnificant yet. Do you have a chip or programmer or anything like that? If you do try putting it on the highest level and driving it normal most of the time you get better milage as long as you stay out of it. It was some advice from a guy on another site I figured no way but it's been workin.

Flush all your fluids, tranny, diffs, transfer case, replace with a synthetic (I think they're synthetic new). take out anything you don't need to cut down on weight. Run aluminum rims if you aren't already. The differece between aluminum and steel is 13 or 14 lbs a tire and it's rotational weight

I was getting a steady 16 on my 2000 f250 4x4 extended cab with 145k, stock tires, all stock except AIS intake. I think I've got a 4:10 rear end. I changed the front and rear diff with mobile 1 and the transfer case with valvoline synth, then i unplugged the wire to the EBPV cause i thought that might be sticking, then, probably most importantly, I slowed down from 2100-2200 rpm (mid 70's) to 1800-1900 rpm (63-65 mph). I got 18.5 mpg.

I'm going to re hook up the EBPV connector and see if that makes a difference on my next road trip.

Drives me a little crazy going that slow, so I gotta use the cruise control.

That's what worked for me. Good luck.

when i first got the truck i changed all the fluids in it and that was a few years ago. with the tires i have now at about 70 im just a little below 2000 rpm's i dont remember what the rpms were with the stock tires on. with the stock tires on it will get 18 running 65mph. think it would be possible for me to get 220 out of it?
