alariwild Has anyone tried using something like a superchips programmer on their 6.2l engine? Did it give better MPG and if so hoe much?

searcyfarms a little math, cant remember what I paid back in 02 when I ordered my 6.0 extra BUT - I know it had to have been 5000 extra anyways for the diesel.

Add 6500 for studs and had gaskets at 165K along with egr and oil coolers. Stand pipe and o rings, since then upgraded alternator ( old one crapped out ), FICM, Injectors at 250K to the tune of another 4000, so theres another 10500 on top of the 5000ish for the diesel. I personally installed a new EGT sensor/tube, of course other wear/tear items so cant count those.

Now........todays gas prices at my local pump are 2.16 for gas 2.96 for diesel. Im averaging 18K/yr over the 16 yrs ive owned it. That's 1200gal per yr for 15mpg in my 6.0 - if I were to convert to a 6.2 gasser @ 12mpg avg that's 1500 gallons so 1200x2.96 3552 in diesel - 1500x2.16 3240 in gas or 316 bucks cheaper for the gasser/yr to drive not to mention higher costs in oil chg, fuel conditioners, etc......how could a person really justify a diesel? I love my 6.0 now that it has been fixed/updated but at 16y/o its starting to show its age in rust etc...I will likely go back to gas as I cant honestly justify the diesel costs.

medic868 I owned a 2011 F250 6.2 CCSB with 3.73 axle and was only getting around 11.2 mpg, 7.8 when towing 7500lb trailer.
Had the hard 2-3 shift while accelerating down an on ramp while towing my trailer and thought I lost the rear end.
Bought last May & traded this July. Not sure if you all have good ones or I had a bad one but I expected a little better mileage.

guardrail22 These trucks are bricks compared to the 150 and heavier so these numbers aren't surprising. More fuel to go faster because of bad aerodynamics. Thinking about a 6.2 with 430 gears and am watching for any experiences.

mjstef Picked up a grandpa truck in Salem Oregon yesterday and drove back to Montana 700 miles. It is a 2011 F250 4x4 6.2 V8 6 spd auto 3.73 rears and i got it for 20K less than what it would cost me to order the same truck today and it has only 52,000 miles on it. . I ran 70-75 MPH and I went from 200 feet elevation in Salem Oregon up I5 to Portland then 82 east to the Tri-Cities, then 395 North and steadily climbed to Spokane Wa. Elevation @2,000 feet and then over 2 mountain passes going east on 90, one at 3,100 feet (4th of July Pass) and one at 4,700 feet. (Lookout Pass) Then it was rolling hills and 65 MPH max due to deer and elk on the road all the way from St Regis MT up 135 to 200 to 28 to 93 to my valley which sits around 3,000 feet. Mileage was a LOT better than expected. Overall for the trip i averaged just under 55 MPH including around 50 miles total of town driving and the balance interstate and 2 lane roads. She averaged 14.6 MPG and this is coming from 200' elevation over 2 mountain passes home to my valley at 3.000 feet. Best i saw was once i got into Montana on a 100 mile stretch of reasonably level road where i saw 16.3 mpg with the cruise set at 65 MPG. BTW, Yes, i did check 2 tanks on paper and the trip odometer is spot on. Here are some pics I was also locking out gears on the hills and passes to keep it from shifting as well.............

coolfords ... took a trip last week, 1000 miles up and back
I have about 7800 miles on my truck. I was hoping for better mpg but for what I've got its okay. lol
On relatively flat ground @ 65 mph I could get about 16mpg. Over 70 mph about 14.5 mpg. Remember I have a 4x4 short bed with 3.73 gears.

In town daily driving I get 12 - 12.5 mpg on reg gasoline.

In town on E85 I get 10-11 mpg.

I'm told my mpg my go up a bit more when I get over 10k miles but I don't think it will be that much.

FloridaEd Thanks to all who are posting on this thread. I traded a 2001 F-250 SB CC XLT 5.4L in 2 years ago on a Dodge 1500 5.7 CC, and have regretted it ever since. The F-250 was just for groceries and doc's office and Momma's daily driver. It got 12 or so around town and 15 on the road, always driven geezerly by me or Momma... never over 65MPH. My other truck is 2001 F-350 CC Lariat DRW LWB 7.3L (198K miles) used to haul an RV. I recently downsized from 12000# 5'ver to 7500# travel trailer and am considering a 2015 F-250 CC SWB XLT 6.2L truck. I'm pleased to see that the 6.2L has handled a 10K 5'ver in some hills. Thanks to Iggy from AZ for the info. I'm still on the fence about letting go of my old 7.3, still smarting from my move to Mopar and ensuing disappointment.

But thanks to all for the info.

I know the SRW does. Thought the dually allowed a 4.10.

T diesel They only come 3.73 or 4.30.

Smokewagun Pretty impressive, although the smoke heads will grumble. Most likely the 4.10 rear on that one. Only confirms I'd only take one with the 4.30 unless I have no option to order, with a SWR. Thanks for the find.

I really only need the smoker for pulling our 10,000 lb. Travel trailer 12x a year. Even if the 6.2L only nets 13mpg for me, its only$700 additional a year for gas. Thats a far cry fron $8000 for the smoker. Kind of chicken to order one without driving one. And as a daily driver, im not sure what to expect.
