To the guy with the magical 30+MPG Excursion

[racerxxx]

x2 for there gas jobs that is..also dodge trucks doors rust out i havent seen a dodge truck w/o rust there ever and i heard the 6.0s leak oil bad after xxxxxx many miles...the 7.3 s will go for ever just like the cummings..and to who ever said their cummings gets 16 mpgs all day long that funny cuz my dads ram 1500 v6 gets 13mpg

Your pop's needs to upgrade, my old mans 06 Ram quad cab with 5.7 Hemi and MDS clicks off at almost 20 MPG down the highway @ around 70 mph

get rid of the egr system and cooler and a 4inch down pipe and arp head studs and eliminate the restrictive bends in the 6.0 fuel system and you can make more power and awesome milage for a 4x4 crew cab with 3;73 gears and 285/75r 16 bfg all terains i am getting verry good mlilage aprox 960 per tank with off road and 850isjh with on road diesel and its a 32 gallon tank.

Quick question off topic same subject;
I'm looking at getting a 7.3 powerstroke, 99-03 twin turbo, is there anything i should be on the look out for? Any bad indicators?

Also, what is the difference between on road and off road diesel?

[deathman53]

the difference between on and off road diesel is mostly taxes being payed on it. Since no taxes payed its dyed red to make it different. Some say its has higher ppm of sulfur. The only twin turbo fords were 06+, 7.3's were a single turbo. I would check the waste gate on the turbo for any leakage, that indicates it needs to be rebuild or new, the fuel filter body for leaking, if the water pump housing leaks and output of alternator. I had all of those go bad on mine, parking brake cables freeze, front caliper line collapse and caliper seize. Also check the radiator hoses for any spots where they rub and are wearing thin, I also had this happen to mine.

In the words of my buddy who's a diesel mechanic...

"dodge's have the best transmissions out there, very easily rebuildable...."

I typically just stare dumbfounded at that point.

And I will believe what I want on the mileage... fill until the nozzle clicks at a pump, drive a distance, drive back to that same pump and fill until it clicks. then calc your mileage. You won't see the mileage you're claiming, I'll bet my left nut on that.


Not to bust balls, but that's the reason you don't have these outrageous mileage claims on the 7.3 forums...whenever someone comes in and starts saying 30 mpg they get laughed out of there. On here...we gots to be all friendly and nice.

bleh...

Little off topic here, but whats with the ford 6.0 being junk...? The old mans 07 1 ton has the 6.0 with 95 thousand km's and bout 3600 hours, With a crane, tool box, flat deck ect, set up for work. The only problem he's had so far is the Egr valve crapping out...seems to get decent mileage not sure on the exact numbers.....anyone?

the 6.0's and the 6.4's are junk. i know for a fact working on the 6.0 is a PAIN in the arse. Ford bought back tons of them.

theres a reason the 6.0 and the 6.4 were so short-lived and that Navistar isnt making their motors anymore...

Stay away from early 1999. Go with a late (1999.5) or later, forget the exact build date you need to get that though. Other than that, make sure you have a chance to start it cold. See how it runs off first start up, feel for shaking/running rough, if it's real cold out some white smoke for a period of time depending on temp is ok...mine will white smoke for about 30 seconds in 30 degree weather, watch the exhaust for excessive smoke. When you drive it, take it easy and let it warm up a bit...at least to operate temp, try and find you a steep hill and mat the accelerator. You want to feel for any shuddering/missing. Injectors, glow plug relays, and glow plugs are somewhat common failure items mostly due to lack of maintenance. You can buy a set of injectors, glow plugs, and UVC's for about 1,000$ from Pensacola Diesel. If you bring it to a shop to have it installed look at app. 600-1000 for labor.

There you go. Lots of good informational videos there, I really like the one about "Spot" the shop truck, 798,000 miles on the engine a rod failed and destroyed the block. He got the truck with 700K on it then proceded to beat the out of it, nitrous, dyno tests, hauling stuff, etc etc.

check diesel specialists here in louisiana...they do things right.

[MagicJames]

J.D. That youtube thing is amazing....
I've watched 2 hours of video already and I am just wow-ed...

Makes me want to run out and buy a Powerstroke .... NOW

[MagicJames]

Maybe i should just look at a powerstroke forum as opposed to asking questions here....

Oh...and if you do anything with Pensacola diesel...plan on doing it more than once...
I've stayed outta this thread cause I'm no newbie anymore to powerstroke's and know how the forums can be.... I'm amazed at the misinformation though... All I will say is do your own research and keep an open mind. Only you know what you want and what you can afford.

[J.D.]

Are you saying misinformation in this thread??? If I'm wrong about anything I've said, please feel free to correct me. I'm still trying to learn more about these myself. I personally like superdutydiesel.com as far as a forum goes. And as far as Pensacola Diesel, I never said they were good haha...they just have a whole setup cheap. What's your experience with them?? I know a guy that's had some trouble with them too...but a grand for a complete injector job is a cheap get-me-by.

Are you guys that are claiming 25-30mpg actually calculating it the old fashioned way or are you relying on what the computer is displaying inside the truck? Those things are notoriously inaccurate and when you do some mods to the truck it makes them even more inaccurate. I could maybe believe 25 with a 2wd standard cab that was running flat highway and running pretty much as light as possible (no gear, cargo, toolbox, etc...) but 30 from a 4x4 ain't happening, no how, no way. I've been playing with diesels for the better part of ten years and there is something being miscalculated there.

thank you....thank you.

I know someone who has a 350 with a 80hp tune, 6.0 intercooler and new injectors, and shifting at 1100 rpm...yeah 1100...he can't break 23 mpg. His tires are also like 205 or so wide.

I've thought that with new gearing you could get into the high twenties...but I don't know. Seems like if you could keep those rpms low enough you could do well.
