What do you guys think about running JP-8 (Jet Fuel) in my 06. I ran it in my 7.3L and my Duramax no problem, I just added additive or ran half and half/ Will it hurt the EGR system? any ideas?
JP-8 in my 6.0

as many problems as our trucks have just running #2..I personally wouldn't risk it..
what do you benefit from it?
does the benefit outweigh the possible damage to injectors and other fuel components.

I really don't think that there is any benefit from using it. I don't see how it would damage the injectors or anything at all. That is all we use here and have not had a problem.

I used to use JP-4 (yeah, long time ago i know) in my diesels back in the 80's never had a problem, would run about 1 quart to 10 gals, got really good mpg, about 10 mpg better than without. couldn't do it all them time, so it was just every once in a while. really cleans out the engine. JP-8 is even cleaner than JP-4 (or so I am told) so it should be better, so I wouldnt run it straight. becuz it seems the tree huggers got to the jet fuel first, (ie used to be JP-4 and I believe there is no more of that)

i would deffinately mix! our 6.0s over here now are puking up injectors and having constant egr problems. the ones the get #2 arent having these troubles. i would not recomend it after seeing what it has done to our 04 and 06 models. they seem to be doing better now that we are running Dex III in them. just my input after seeing the troubles first hand. Good luck!

If you read the know your fuels sticky you saw that I didn't say much about jet fuel. I talked to my airforce buddy who explained to me that jet fuels don't really need to lubricate well, they just need to burn well. I would be very certain that I used plenty of Power Service, 2 stroke oil, biodiesel etc... as an additive to guard against injector damage.

One of the reasons JP-4 isn't used any more is because of the low flash point. The Navy used JP-5 in the Carriers because its flash point was higher than JP-4. If you run JP-8 stay away from an additive called JP-8+100. When it was first tested it left engines super clean, however the fuel tanks had to be squeaky clean, if not, the additive removed all dirt, water, algae, whatever was in the tank and clogged up the fuel lines.
Like Badfish mentioned you will probably want to add something to help with lubricating. While military vehicles (a lot anyways) can run on jet fuel, there is a reason base fuels, POL, whoever still carries diesel fuel.
On a side note, I would love to have that smell come out of my exhaust!!!!!

·I am in the Army at Fort Campbell KY and I have been using it for ever. I run a 7.3 but I dont think it will have that big of an affect.

i am in the military to and am teh base fuel king . and i have access to about 100,000 gallon of jp-5 and i have ran a bnunch in my 7.3 and have had no problem. we use it in out 16 cylinder engines with no problems either. it just runs hotter. but you will burn out the carbon build up cause a lot of us light load our diesels anyway. i have also ran straight f-76 in my truck its just a marine diesel fuel. and its not ulsd. juts be careful and not use jp-4 they don't even allow it onboard teh ships. teh aircraft inbound with it have to dump it before landing. it is very dangerous. but they mostly get it overseas. thats why teh airforce and teh navy and marines use jp-8 or jp-5 for our primary fuel. just be sure to use an egt gauge and monitor your temps.

i work on army helicopters here in Alaska and we still use JP-4 here as far as JP-8 you wont have a problem running that in your 6.0 the army uses that for every piece of equipment that is diesel if it was that bad they would not gamble with billions of dollars (probably more) of equipment look at all those hummers running oh and we put them in the duramax engines every day
