jp8 fuel

Would it be a bad idea to run jp8 in my 7.3? Jp8 is what all diesel military vehicles run

I am personally hesitant to run anything than number 2, but i know people who run red diesel (illegal, dont do it lol) and it causes no problem. I dont see why it would be bad.

Jp8 is highly refined diesel fuel.

I dont remember what it stands for, but its jet fuel.

Did some research, JP= Jet Propellant

However, the military uses it in ALL diesel powered vehicles, generators, and appliances. It is known to cause trouble in low compression diesel engines (14:1) such as rough idle, hard starts, but our engines shouldnt be affected.

JP8 has been known to cause increased wear on the exhaust valves

I didn't want to say that, cause when I get stuff wrong, a few people really like to flame me, but that was what I thought it was.

Jet Fuel is highly refined diesel fuel, That is all.
Means its going to burn a lot cleaner than what we are used to, prolly why you'd get valve damage.

You can run it but is doesn't really have a lot of lube to it so add some 2 stroke oil to it.
If it was me I'd run it 50/50 Deisel/jp8

A better question is where to get it if it works? Or how much? The valve wear is from lack of lubricity. Not sure how much 2 cycle you would need to offset it.

Not all military diesels run it. The only thing I've seen it run in is AGE equipment on the flight line. All diesel trucks run no.2 diesel in them. They still have to abide by federal laws. The army may run it in some of there heavy trucks but I'm not sure.

Most military vehicles from my reading will run jp8 and anything lower down to UMO.

Tanks can run on jp8 to gasoline. Just about anything combustible you can put in them.

But yes, they have to follow regulations as well.
Doesn't mean that they do elsewhere.

They may not run it all the time, but all of them are capable of running it. The two main fuels the mlitary uses is #2 and jp8.
The navy uses a fuel similiar to jp8, jp5, which appearently is less flamable and is more suited for use on carriers and such.

In 1997 or 1998 the Army switched from #2 to JP8 (at Ft. Bragg anyway) as their equipment fuel. I clearly remember the filter changes we had to do on everything because the JP8 basically cleaned out the fuel system. When we deployed to Central America for a hurricane we had to burn #2 again and go throught the whole filter change routine when we got back.
