JP8 (jet fuel) in place of diesel

I bet this has been asked before so I need to find out if I can use JP8 in place of diesel road fuel. What problems might occur ?? Thanks

" Jet fuel is often used in ground support vehicles at airports, instead of diesel. The United States military makes heavy use of JP-8, for instance. However, jet fuel tends to have poor lubricating ability in comparison to diesel, thereby increasing wear on fuel pumps and other related engine parts. Civilian vehicles tend to disallow its use, or require that an additive be mixed with the jet fuel in order to restore its lubricity. Jet fuel is also significantly more expensive than diesel, so using it in ground vehicles is considered by some to be wasteful"

Why would you want to use jet fuel?

I've seen JP-8 used in chevy kodiaks and in international fl's, not sure how new they where or there emissions status. The kodiaks had cats in them. They ran fine the year that I used them and the year before me. 6.4's get pricy if your the one flippen the bill for repairs. I would do a little more research before you try it.

I belive that you are thinking of JP4/5. I know that JP stands for Jet Perpulsion but JP4/5 is more of a jet fuel than JP8. The JP4/5 feels like a solvent, very thin and JP8 has an oily feel pretty close to DF2. JP8 has become pretty much the standard fuel for not only the US Military but for NATO as well. It powers everything from heaters, trucks, helicopters and planes. The JP8 does have a lower temp before it gells (we used it in the Balkins) than DF2. I am not sure that it can even be purchased outside of Government use. Hope this helped.

If you are going to use it make sure that you get a few extra fuel filters because when you switch from DF2 to JP8 it will break alot of junk loose in the fuel system so just be ready to change them at least once. We had a heck of a time espically with the HEMMTS when we changed over.

A little while back I was working on the building of a fuel transfer manifold for a local airport. While we were there we would see some of the employees filling up their trucks from the 55 gal. drums next to the fuel tanks. They were using the "contaminated fuel" in their trucks. We warned them on one day that we had just dumped several gallons into the drum and any sediment in there was probably stirred up.

I wouldn't risk it with the DPF attached. Is JP-8 high sulfur?

I am in the military and have seen JP8 used in many diesel vehicles while in deployed locations over the years. Overall I can say from my experience that it does not do well for these trucks at all. These are old trucks mostly chevys prior to the days of emissions and all that other stuff. I would not recommend it at all with the emissions and other stuff on these new motors.

Hey everyone, I am in the Marines and wanted to throw my two cents in as well. Although I have to say I am using JP-5 not JP-8. But none the less I ran it in my 2003 F-250 and put on 230,000 before selling that truck, also my gunny ran it in a 1997 F-350 for many hard miles towing a gooseneck. Currently I have been running it in my 2008 for roughly 10,000 miles. So far things are good.....except for the damage a dealership did in Arizona and now my trustworthy dealership in South Carolina is fixing. I will cross my fingers to continue hoping that I don't see problems running this JP-5. I will add that I do use Power Service diesel clean with every tank. I will admit that I worry the fuel may effect the EGR valve/coolers and DPF eventually, but the money saved on fuel would in the end pay for quite a bit. And thankfully I have an extremely good dealership that takes care of my truck out here.

I know what "free" means. I think free in this case means free for you, costs the armed forces :-p

Ha, just messin with you. I was thinking about using JP-8 also, but I got the same feedback as what is said here.

The JP to stay away from is JP-8-100. The "dash 100" is not allowed in Navy aircraft as the harsh cleaning additives will strip everything from fuel tanks and lines leading to plugged filters and injectors.
