haha i noticed the valve thing right away
anyways, about av gas, av gas comes in many octanes the most popular are 80 and 100 LL (low lead) i beleave that the the new 80 octane av gas has no lead but used to contain .5 mill/liter. 100 LL contains 2.0 mill./liter
av gas is much more stable than auto gas, it can be stored for longer periods and has a vaper presure of 5-7. however the fuel should be agitated regularly. the fuel weighs 6 pounds per gallon and has 20,000 BTU's a gal.
as for jet fuel, its kinda like kerosine..
has a vaper presure of 2-3 psi, its heavyer than av gas (more dence). it has a higher heat value and contains some oil for lubrication. however it tends to hold water so micro organisums can grow in it. oh and it has no octane rating they use designation numbers. anyways while the topic was brought up i figured some of you guys would be interested just how much lead is in the "low lead" i think that the old leaded auto gas was 1.0 mill/liter... the fuel used in some old war planes had up to 6.0 mill/liter of tetraethel lead..
