Interesting thing happened today. Here I am over at the airport installing new equipment at the Sheriff's helicopter hanger, I had taken my own truck since my county Jeep is in the shop with some malady from running that reformulated gasoline and one of the ground support guys asks if I want a bunch of clean Jet-A?

I ask him what I would do with it and he says I can run it in my truck like some crazy hi-test version of diesel fuel and that they get hundreds of gallons of the stuff that they pump back out of the trucks and tanks they aren't allowed to put back in the airplanes. He says that a few of the maintenance guys have diesels and they run it all the time.

I took his number, supposedly all you can eat deal. With diesel at $2.31/Gal here, it is tempting but I don't want to fhttp://www.dieselplace.com/forum/images/smilies/censored.gifk my truck up.

Thanks in advance!

Stuff is quite a bit thinner and the pump will wear out sooner. Would work best with an inline pump which can take a sustained diet of this stuff. Rotatary pumps need to have some lubrication, perhaps just a little to a tank full would be O.K.

Well the guy said that they put ATF in the stuff to make their trucks "run better" but I didn't like the idea much. Jeez, I wish I had a turbine to run the stuff through http://www.dieselplace.com/forum/images/smilies/tongue.gif

While I lived in Alaska, I knew an engineer that worked at the local oil refinener and he told me that the diesel I used in my truck and the JP-8 that we used in our airplanes came out of the same line. We used JP-8 in all of our diesel trucks and equipment at base. That's all I know bout that.

worked at an airport, we used to mix in jet-a with diesel and run through racor filters to clean junk out from fuel being long storage, jet-a dosn't have parifin(wax) and sulfer to lube pump and injectors you could used fuel conditioner to make up lube, maybe double up. jet-a works as system cleaner, picks up varnish and deposited material in fuel lines. so expect to change filters.

When I was in the USAF we ran JP-8 and JP-4 in our Dodge cummins, never had a problem.

Was talking with a friend who got back from Iraq a couple of months ago. He mentioned they run JP-8 in their humvees with the 6.2s and 6.5s. They mix in a quart of ATF with every tank or every other tank for lubrication.

JP-8, JP-7, JP-6 or JP-4 ......... what's the difference?

JP-4 and JP-8 have the same use capacity, JP-4 has benzine in it a nasty chemical that is not good for humans to come in contact with the military has phased this out and replaced it with JP-8 which has no benzine. JP-7 is thick like syrup to prevent freezing at realy high altitudes like over 80,000 feet. I don't have any info on JP-6.

I wonder what the 747 Presidential juicer burns?

NVM,
Have you forgotten so fast, Ships MWBs & Capt.'s Gig ran JP-5 in their Detroits & Westebekes, JP fuels are acceptable to use in Diesels only problem we had was if setting too long it's low biocide content did not inhibit algeae growth in the fuel, it was intermixable with DFM. This fuel does it have red dye in it?? that would be your big problem if you get caught with dyed fuel could be a serious fine. If you decided to run it I would add a good lubricity additive with a biocide in it, and probably not run 100% but a blend of Diesel & JP.

JP-8, JP-7, JP-6 or JP-4 ......... what's the difference?From what I've been told is that JP-8 is basicly diesel, JP-4's flame point is close to gas, this stuff lites off easily where JP-8 won't even fire off at times such as cold cold weather. JP-5 was for navy aircraft. JP-7 was for the SR-71 hi flying spy plane. Not sure about the others but they had their special uses somewhere out there I bet.

Here something else I found on this at this site

<TABLE cellSpacing=0 cellPadding=0 width="100%" border=0><TBODY><TR><TD class=contentheading2 vAlign=top>1.1 What are jet fuels JP-5 and JP-8?</TD></TR><TR><TD vAlign=top>Propellants are substances that move other objects or give thrust. JP-5 and JP-8 stand for jet propellant–5 and jet propellant–8. They are used by the military as aircraft fuels. JP-5 is the U.S. Navy's primary jet fuel, and JP-8 is one of the jet fuels used by the U.S. Air Force. Both JP-5 and JP-8 are colorless liquids and smell like kerosene. Kerosene is the primary substance in each. Although JP-5 and JP-8 are liquids at room temperature, they can also change into gas vapor. Both JP-5 and JP-8 are flammable. JP-5 and JP-8 can be made from refining crude petroleum oil deposits found underground and under the ocean floor. They can also be made from shale oil found in rock. Because kerosene (which is also referred to as fuel oil no. 1) is the main part of JP-5 and JP-8, the profile sometimes uses the word kerosene and other names that it can be called instead of the words JP-5 and JP-8. In addition to kerosene, both JP-5 and JP-8 contain various additives according to standards specified by the U.S. Air Force and U.S. Navy. Other common names for JP-5, JP-8, and kerosene are these:


fuel oil no. 1
straight-run kerosene
kerosine
range oil
Deobase (the trade name of a clear, white, deodorized kerosene)
coal oil
In this profile, JP-5 and JP-8 are discussed together.

TD,

No I hadn't but the injection system on these 6.5s is kinda different compared to the Captain's Gig. Besides, the EN's could never keep that thing running long enough for me to get a good feeling about it http://www.dieselplace.com/forum/images/smilies/eek.gif We had RHIB boats instead of an MWB and fed it DFM. Forget indeed! I have pics of several times our gig got towed back to the ship by a civilian craft.

IF and I mean IF I decide to run this stuff, it sounds like I want to use some kind of treatment in it for lubricity and get an auxillary filter to make sure I don't kill my IP. Possibly even do a mix with #2.

Reno is in a strange situation fuel wise. It all comes from the Richmond, California refineries and is pumped through a pipeline over the Sierra's to the tank farm in Sparks. Our fuel prices move around like the stock market and if someone farts at the refineries, we can, and have seen prices skyrocket, limits on the amount of fuel you can buy (the truckers love it when they come through town and see $2.88/gal with a 50 gallon limit)
Currently, the price has gone up 20 cents a gallon because "the refineries are doing their March maintenance early and lower output is resulting in a price spike" http://www.dieselplace.com/forum/images/smilies/censored.gifhttp://www.dieselplace.com/forum/images/smilies/censored.gifhttp://www.dieselplace.com/forum/images/smilies/censored.gif
