BRUISER

So having a conversation with a freind that works at the airport and he stated that all their diesel trucks run on Diesel Jet fuel.

he said it is really just very clean diesel compared to the diesel you or I would get at local pump. He said they have never had an issue with any of there rigs.

Has anyone ever run this stuff?

I am curious as I have never heard of it, except working in jet engines?
I thought the octane was different then what we run?

Are you talking about JP5 or JP8? When I worked on the military base I asked about running these fuels...and got mixed answers. From what I remember either the cetane ratings or the amount of lubricity was not healthy for the common rail 04 I had at the time. Sorry, not much help maybe someone on here has ran it.

I think he said they were like Jet A or Jet A1 or something like that..

I never knew there was a thing as diesel jet fuel....Learn something new everyday..

It might be like the JP 8. The military runs than in almost every vehicle but there designed to use it. They can be ran on diesel and I've seen them put gas in one of the trucks before and it still ran alright.

Jet A is very dry fuel. I would not run 100% in a tank.
Mix in some 2 cycle oil or better, fill 50% with street diesel and should be no problems.

JET A-1 fuel is essentially identical to JP-8 except it does not have three additives required in JP-8: a fuel system icing inhibitor, a corrosion inhibitor, and a static dissipater additive. They are, inlarge part, refined Kerosene.
Hot JP-8 fuel reduces the life of fuel pumps on some diesel engines, so avoid using JP-8 or Jet A-1 extensively in hot weather, and keep the fuel tank as full as possible to reduce fuel temperature.
Diesel fuel #2 and water separate completely; JP-8 fuel and water do not. A fuel/water separator (like on a FASS or an Airdog) will not be able to remove suspended water from JP-8 or Jet A-1.

Commercial jet planes use Jet A mostly. Whenever fuel is drained from an aircraft it cannot be mixed with fuel for other aircraft from different airlines and must go back into the fuel tanks of an aircraft of the same airline. For checking or maintenance it's usually in "small quantities" of 5 gallons up to 50 gallons and this goes to waste as it's too little to get a separate tanker for. The airlines have to pay to dispose of this fuel and used to turn a blind eye to employees using it in their vehicles.
The fuel that goes into a jet aircraft is extremely clean but lacks lubrication so as has been suggested add a little oil or 2 stroke oil to it, NOT jet aircraft oil or aircraft hydraulic oil. However the fuel that is drained from the aircraft is not always clean as it is mostly the fuel tank sumps that get drained to check for a build up of moisture.

Stanadyne makes a formula just for "dry" fuels like jet fuel. Where I work we use JP-5 in our planes and our fuel samples get dumped in a fuel bowser. The fire department uses it for training fires. What a waste...

you can run jp-5 in your rigs, just add 10% wmo. it works real well, just smells a little. i have ran lots of it at time.

In a common rail, like mine, you have to be careful. In a mechanical fuel pump, I don't think it's a problem. ( the P pump is lubed with the engine oil, correct?)

I ran some in mine at a 3:1 ratio with some ashless 2 stroke, did not notice any problems. That was JP5. I only did it once or twice.
