JP8 or Jet fuel

[GS247]

I was just talking with a guy that runs JP8 fuel with some Marvel Mistry Oil in his 2000 7.3L Excursion and gets up to 32mpg on the freeway. Has anyone ran JP8 or Jet fuel in your truck? Is it safe for the 6.0L. There is another guy that all he runs is Jet fuel with some Marvel in his '98 Cummins.

Funny you brought this up. I had to get a government vehicle the other day to take to 29 palms, it was an 05 powerstroke flat bed. I had 1/4 tank of what i assume to be regular diesel in it. I requested a fuel key and they gave me jp8 key. Needless to say, i filled her up against my better judgement and about 60 miles down the road the CEL came on. I was unable to shoot a code to find out what the CEL was for. However, I didn't notice much of a dif in performance or anything. I heard you can get away with using jp8, but it somethign you don't really want to do over a period of time due to it being a crappier grade of diesel than that which we are already running. Hopefully someone with more knowledge chimes in because I'd like to know the facts about this.

JP8 is what is used in the HMMWVs (hummers) and jp10 is used in aircraft from what i understand

JetA is the only thing we have here, and i know you would have to add some type of lubricant.

oh yeah this is strictly for off road purposes only.

32 mpg with an Excursion, is the guy burning it in his truck or drinking it?

the more i look in to this the more it looks like a bad idea in the 6.0L

He's drinking it.

We use JP5 locally, but also get JP8 at some other bases.

I would try it with lots of 2 stroke if I could get my truck over to the pumps without pissing off a lot of people.

Isn't Jet fuel pretty much kerosene that has been filtered really well? I know when getting on a comerical flight you can get a whiff of jet exhaust and it smells like burning kerosene.
