2006 F250 6.0 milage ???

[bigbrother44]

Hey Bigbrother44,
Can you find out what flash your buddy got for his truck, because when I talked to my dealer they told me that there wasn't a flash for my truck.
I'm curious to know if he was pulling my leg.

Thanks, Jeff

Jeff-

I dunno what the flash was. His was an 06, but this was a casual conversation with a fleet sales manager while I was working with him on some cars for work. Wish I could help more. Maybe your truck has the latest flash, and his was an earlier one? He is an older guy, don't know how he drives...

I get about 10-14 with the gooseneck. and 15-18 driving around. I could get better. But im alittle hard on it. mine is not an o6. but does have an update tune

I was getting about 17-18 mpg with only an aftermarket exhaust, driving 70 mph. I've installed a banks sixgun and their intake kit. ahaven't had it long enough for an eval though. The thing that gets me is how are all these 6.0's getting 20 or more mpg. I had my tuner set on "3" and still was getting only 17 mpg. Now I'm trying setting "2" Setting "4" by the way would smoke the tires, but only 14 mpg.

Drive like a grandpa, and keep it between 55-60 mph, turn on the cruise control and you should see over 20 mpg.

Sounds like I am in the same boat. I get about 15 around town 18 on a freeway cruise 70-80 and about 10 towing a 13000 lbs 5th wheel at about 55-65.

I would put in lvl 6 or on Speed Loader (if you have it) that's where I've always gotten the best mileage with my 6gun, but of course you still have to keep your foot out of it for the better mileage. Mine rarely leaves the Speed Loader setting, and before I lifted the truck I'd get 21-22 MPG on the freeway at 70-75 MPH, after the lift and 38" tires I get 15-16 MPG (hand calculated) if I put the cruise on at 70-75

htg900,
Have you had our truck in 4wd any time lately? The reason I ask, I have recently been experiencing some bad milage as well. My T-case was still in 4wd. I did not think too much of the milage because I just put on my new wheels and tires. I was under the truck the other day and the front driveshaft would not turn. It should turn freely in 2wd with no problems. I had to put the truck in and out of 4wd a couple of times to get it to come free and it turns freely now. I will have to drive a while to see if the milage is up again.

I have had no work done at the dealership so I do not have any flash problems.

I hope this helps.
Andy

YIKES!!! I wouldn't mention this to any Ford shops!

2006 fuel mileage

My 6.0 F-250 KR gets 19.7 at 70-75, and I hit 22 if I stayed at 60. Stock with Amsoil 5W-30.

I have a 2005 e-350 6.0 and I only get 13.8 stock, so I dont see where you guys are getting the milage figures
