Re: [MBZ] Jet-A
Whatever Jet -A is, it's NOT ASTM Diesel fuel by any stretch. More like low volatility gasoline, in fact. Did a project a few years back attempting to identify some hydrocarbon liquid after a flood. Only thing I could figure it was was maybe lighter fluid, but I ran some GC testing on Jet-A along with some other things. Gelling resistance is necessary for high altitude operation -- one of the selling points of JP-4 was that it wouldn't gel. It WOULD generate significant vapor pressure at room temp though -- in fact it was typically called "wide cut gasoline" and was eventually banned after a couple jets exploded due to excessive fuel vapor in the tanks.

Re: [MBZ] Jet-A
Prist is to kill algae (or at least it was 40 yr ago when I was refueling airplanes). It came in a spray can with a long hose and a clip where you could attach the end to the Jet-A nozzle, and squirt it while refueling so as to get it well mixed. I never understood the issue because most of the Jet-A airplanes and helos burned it all up in the next few hours, but whatever...I guess it kept the nasties out of the fuel system. Jet-A has a lower vapor pressure so it does not decide to turn into vapor at altitude. Or gel up when it gets cold. --R On 10/3/12 10:49 PM, relng...@aol.com wrote: ...I'll bet it would run on diesel just fine, but I wouldn't ride in that plane!.. The fuel caps are placarded, JET-A ONLY. The reason the engine was engineered for Jet-A is that Jet-A is available at every major airport on the planet and diesel fuel is not. If diesel were permitted, some damned fool would start collecting used fryer grease. There is also a design feature that eliminates the need for Prist, a common Jet-A additive. At high altitude where it's cold, there is the danger of gelling. There is also the question of unapproved fuels which is federally regulated.
