Jet fuel?!

[JFrey]

I have some Jet fuel! (JP-5) and i am under the impression that it is pretty much diesel fuel. Is this true and can i use itin my 04. 5/H. O. Does it have the lubrication qaulitys for the fuel system? Any help would be appreciated

You can run it just fine. Just add some 2 stroke oil to it. I would normally add 1qt of 2-stroke to every 5 gallons of JP. Overkill? Most likely. Had as much as 25 gallons in the tank at one time. Only used about a gal of 2-stroke in those 25 gallons though. Truck didn't care and never missed a beat.

I've run well over a thousand gallons of JP-8 in the past 4 years. I have only run about 120 gallons of regular diesel in that time and it was all at once on a long trip. I have added hydraulic fluid or oil here and there for the JP8, not as much as everyone recommends or as much as I probably should have but I have had 0 problems so far.

I have run a couple hundred gallons of JP-8 in the past with no issues. JP-5 is similar to JP-8 and both are very close to Kerosene, which can be blended with #2 diesel in lieu of using #1 in cold climates.

The military uses it in just about everything they have with no problems.

thanks for the info everyone. i see no problems, i think i will use lucas or some other additive to be 100% confident. Also i plan to use some type of primary filtration in the future as well.

If it were me, I'd be adding a lot of lubricity agent. Remember, your CP-3 is fuel lubricated.

I beleave stanadyne fuel additive was developed for use in military (diesel)vehicels in desert storm that used jp8 . They were having lots of pump&injector problems.

 

[gbbeadie]

You are correct Tim.

Curious, where you getting your fuel? Using a Gvt. Card?

Why did i thing JP-5 was kerosene? Maybe it was JP-4.....

It is kerosene blended with other things. JP-5 is less volatile than JP-4.



JP-4 is a 50/50 blend of avgas and kerosene. It was replaced by JP-8 in the military which was using Naptha as the primary blend agent. I'm not sure if that is still correct or not.



So as far as using jet fuel, it depends on the blend as to how it will work in your engine. I would use the JP-4 very sparingling because of the gasoline.



I worked at a fuel storage terminal when I was in college and we would receive and store jet fuel for the Air Force. We had a tank bottom go out and contaminate the area. Somehow, the "light ends" of the fuel were lit and it was like a mini version of the Northern Lights. There were wisps of blue flame in the air that lasted for days until it finally rained and extinguished it. It was like an alcohol fire. We couldn't see the flames until dark. Must have been the Naptha.

If I remember correctly, the BTU's of kerosene are significantly lower than that of #2 LSD. Hence my significantly lower fuel mileage in the winter. The terminal does a 60/40 split of LSD and K1 to make a winter blend. Kerosene doesn't freeze outside, and LSD turns into a ball of wax. I can watch my MPG's slowly climb in the early spring as the older winter fuel blends out of the gas station tank.



I don't know about the parafins and what not of jet fuel, but I would want to know that the lubricity factor is such as to protect my fuel injection pump. Irving Arctic Diesel is supposed to be one of the best LSD products around for Winter blend, due to their additives. They are proprietary so I guess there is no way to really tell. Citgo Motiva LSD sucks, and I have seen big drops in fuel mileage with that fuel and it was summer diesel.



What kind of fuel mileage do you get with Jet fuel?

JP-5 = JetA = Kerosene + Additives

Why did i thing JP-5 was kerosene? Maybe it was JP-4.....

JP-5 is the same as Jet A, Which is basically Kerosene with aditives. JP-4 (Jet B) is Kerosene with 25% Unleaded Gasoline added for cold weather preformance, Starting, cold flow, ect... Both have some aditives for Lubrication, however I run some 2-cycle lube (200:1) when I can get some Jet-A, as I have a VP-44 on my truck. BTW, JP-8 is Jet A1, in turbine AC is pretty much interchangeable w/ JP-8.

Cool Moose,



Now how am i going to remember that?:-laf



What little i know of the make up of Jet fuel comes from growing up on Air Force Bases. The Kerosene part because of the "KC"-135 Stratotanker. My next door neighbor was a boom operator. I always thought it a little nuts to go fly around with all that fuel. I do remember how hot it burns when the Crash Crew set the mock aircraft on fire for practice. They would pour on the JP4 and set it ablaze! Holy COW! You could feel the heat from well over a quarter mile away! Those guys would stand there in there little silver suits putting it out. God bless those crazy folk! You couldn't pay me enough to do that! Of course, I did end up driving Petro tankers for a few years. They burn pretty hot too.

I thought that JP-5 was just normal diesel with no additives and really filtered well.
