Jet fuel
#12
Yeah, when I was in Iraq they had problems with the JP8 eatin up injection pumps on HMMWV's and duece and halfs. They wouldn't even put it in the newer MRAPs and mine clearing BUFFALOs. I think K50 is right is acts like a solvent and eats up the seals in everything invved with the fueling system.

My 01 dodge owners manual said it is safe to use jet a for a short emergency. It is some number 2 diesel mixed with kerosene.
Military jet fuels
Military organisations around the world use a different classification system of JP numbers. Some are almost identical to their civilian counterparts and differ only by the amounts of a few additives; Jet A-1 is similar to JP-8, Jet B is similar to JP-4. Other military fuels are highly specialized products and are developed for very specific applications. JP-5 fuel is fairly common, and was introduced to reduce the risk of fire on aircraft carriers (has a higher flash point - a minimum of 60 °C). Other fuels were specific to one type of aircraft. JP-6 was developed specifically for the XB-70 Valkyrie and JP-7 for the SR-71 Blackbird. Both these fuels were engineered to have a high flash point to better cope with the heat and stresses of high speed supersonic flight. One aircraft-specific jet fuel still in use by the United States Air Force is JPTS, which was developed in 1956 for the Lockheed U-2 spy plane.
Jet fuels are sometimes classified as kerosene or naphtha-type.Kerosene-type fuels include Jet A, Jet A1, JP-5 and JP-8. Naphtha-type jet fuels, sometimes referred to as "wide-cut" jet fuel, include Jet B and JP-4.
Jet fuel is clear to straw colored. The most common fuel is an unleaded/paraffin (kerosene) oil-based fuel classified as Jet A-1 (otherwise known as AVTUR), which is produced to an internationally standardized set of specifications..
The only other jet fuel that is commonly used in civilian turbine engine-powered aviation is called Jet B, a fuel in the naphtha-kerosene region that is used for its enhanced cold-weather performance. However, Jet B's lighter composition makes it more dangerous to handle, and it is thus restricted only to areas where its cold-weather characteristics are absolutely necessary.
Jet fuel is a mixture of a large number of different hydrocarbons, possibly as many as a thousand or more. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, freezing point or smoke point. Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 carbon numbers; wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15 carbon numbers.

#2 diesel mixed with kerosene is "Arctic Blend", not Jet A. I'd imagine you have run #2 before, as that is what is normally at the pump.

Ha HA yep typo. #2 at the pump.. All diesel has alot of kerosene in it, but i dont think jp8 is the same as number 1 diesel. Your getting a totally different blend of fuel up in AK than we do here. it varies from coast to coast well globally actually.. You probably get alot more number 1 mixed because of the low temperatures than we do here, and us more so than down south. at least for winter months.
good link.

DO NOT RUN THIS STUFF IN YOUR TRUCK...IT WILL CAUSE OVER HEATING PROBLEMS, PUMP LUBRICATION PROBLEMS, IT WILL EAT STUFF UP...LIKE AF1 STATED ABOVE, THE NEWER ENGINES DONT LIKE IT, EVEN THOUGH THEY RUN IT IN THEM
If you mix JP8 with Diesel #2, you get Diesel #1, if going by the Governments standards...You also have 2 grades of JP8, which are Aviation and Ground, Aviation is much cleaner and has higher additive content...
I worked on the world's largest fuel farm here in Iraq for 10 months, now I am at another fuel farm working...
