Jay,
Just one correction to your reply, It is JP8 that is kerosene based and has a flashpoint of greater that 100F. JP4 is naphtha based more like gasoline and has a flashpoint of neg 20F. Do not try to run JP4 in your diesel or gasoline engine it will not run. I know this from personnel experience (That is another story -young airman without allot of money). Both are military jet fuels and JP4 was mostly used by the Air Force. However, the Air Force got out of the JP4 business in the mid 90's and went to JP8 for most of their aircraft. At that time, for logistics reasons, JP8 was adopted by the Army as their main fuel for all their vehicles. Because of this JP8 is injected with a corrosion and lubrication additive (CI/LI) that allows it to be used as a diesel fuel and not cause premature ware on the engine components.
