...looking to replace my 6.0L Chevy 2500 with a turbo diesel Regular Cab F250 since my truck gets 12mpg on average on the interstate (70 miles round trip to work each day) thus it's sucking down the gas. So what kind of mileage are you guys getting in your Regular Cab trucks in stock form and modified form. Also how reliable are the Ford diesels? Thanks!

my neighbor gets 13 miles per gallon out of his '02

 

Average around 15 in city 18-19 highway. I only have 4500 miles, so I'm assuming to get better with age.

F-250, 6.0ps, crew cab, 4x4, 3.73ls.

 

'99 SD crew cab 3.73's with 7.3 diesel.
Keep the revs below 2000 rpm, in other words out of the turbo and I would get 22-24 in town or on the highway. Cruise at 85mph of the highway and watch it drop to 15-16mpg.

 

You must've got a specially built powerstroke! wish i had that one.
Run 70-75 and like colorado said keep it below or right at 2000 rpm will get its best milage i get 18 on the highway. maybe 14 in town. with an 02 crewcab 4x4 though. maybe a regular cab would get better due to less weight. At least it gets better than my f-150 with a 4.6L in it!

 

I had it made with 3.73's specifically, they were special order only. I bet you got the 4.11's like my brother...that's all he can muster too. Isn't it amazing what gears will do. The truck has enough power to pull down a house and everybody got big gears to boot. In '99 4.56's were an option too, as well as 5.11's in the F450 and F550. Talk about fuel suckers...........

 

I have a '99 F250 superduty crew cab 4x4 with the 7.3L PSD. The truck has 3.73's in the rear end. It has some mods to the exhaust and intake as well as a 3 position chip and stock.

I run my truck under 2000 rpm at all times and try not to goose it as I run with the highest power setting chip (80 hp) most of the time. She runs hot when I launch it off the line, a dark cloud of exhaust off the line darkens most drivers view.

All that said, I check my fuel mileage at every fill, which is usually once a week. At each fill, I add about 2 or 3 oz of canola oil based fuel conditioner I put on about 500 or so miles every week. My mileage has been as low as 14.5 mpg before I put the chip in and is now a consistent 18.5 to 19 mpg, with it's highest point at 19.9.

I've owned the truck since March 2005 and it currently has 278000 km on it or approx 172,800 mi.

I love my truck and it's a blast to drive. I haven't found anything yet that I can't pull, including a loaded 5 ton delivery truck that was broke down.

I'd love to add a pic of it here, but I can't seem to get that done. If anyone can help me with that, it would be most appreciated.

Anyway, that's my two cents worth. Enjoy it if you buy it, they're a blast.

 

Yeah gearing is everything with the psd's. i notice a big dif in economy if i run 2200RPM vs 2000RPM. a couple hundred more and it just sucks the fuel down!
But it could get 9 mpg all the time and i still wouldn't stop driving it. I love my truck!

 

I have a 2000 F350 RC 4x4 auto w/3.73 gears, stock size tires, no bed topper. Tymar intake, 4" exhaust, 4 position chip set on 120 h/p. I just got back from a 3300 mile trip, I set the cruise at 85mph for most of the way and I got only 14mpg. That is running about 2600 rpm.
Another trip of highway driving (5 tank fulls) I averaged 20-21 mpg and I kept the rpm's just below 2000, which is about 68mph. No fuel additives either. I get a consistant 15 mpg in the city.

 

3:73 are what you get with a diesel in an F250 or F350 unless it's a DRW which then you get a choice.

2000 RPM's is kind of a magic mark. I can get 20-22 HWY only, running 60-65 MPH. Over all HWY would be about 20 on a pretty good day. Overall I mean, starting, stopping, slowing etc. 22-24 would be running along, reset overhead adn see 22-25 MPG steadily, until you start making stops or hit good grades.

18-19 is easy on the HWY and that's even with my big *** Excursion. 13-14 MPG towing 7500#.

 

I get about 18-19. With 4" turbo back, intake and programmer.

03' Supercab.

 

I'm wondering how all of you people are getting that good gas mileage on these trucks. I usually only get 14-15mpg mixed city and country FUEL mileage in my diesel. Mine doesn't like gas very much

 

I was going to say, you'll get about 2 miles GAS milage out of a deisel. You'll be towed the rest of the way so MPG will be great!
