Information on octane rating and formulation?

TIA!  DaMan

Military MoGas is 87 octane unleaded.

Anybody know where the name "Mogas" came from?

Motor Gasoline

Wow, I should have asked a long time ago.  Who knows how much farther along my military career might be today if I had not been plagued by that burning question for all these years.[>:/]

Thanks for the info.

JP-4 was a mixture of gasoline and kerosene (the equivelent of civilian Jet-B).  It was pretty volatile and is not used by the Air Force any more since it was considered too dangerous.

JP-5 and JP-8 are considered kerosene-grade fuel and are basically interchangeable with one another (the equivelent of civilian Jet-A).  Most civilian and military aircraft use it now.  It is a little safer since it doesn't have the gasoline content and has to be heated more before it will burn.  Of course, once it gets burning, it doesn't make much difference what it is.

Most small planes use AVGAS which is also called 100LL (100 octane, low-lead).  Obviously, some pretty potent stuff.
