It's all about vapor pressure. You can't just pump mo gas into an aircraft unless you're planning on flying below 6000ft ish. One of the reasons why we use 100LL is because it does not boil above 6000ft. The vapor pressure of 100LL is lower than that of ordinary gasoline. Also, lubrication etc octane are other reasons too.
@fuelban Leaded fuels have lead atoms in them that increase the fuel efficiency almost 4 times... but they banned because it they think it hurts the environment... the effects are dubious. However, in planes any effects would be negligible anyway.
There is no such thing as an "efficient fuel", only efficient means of converting the energy stored in fuel. And lead particles do nothing nothing to increase fuel efficiency; the lead in avgas is there for increasing the octane value and for lubrication of valve components. The usable energy in leaded and unleaded fuels is about the same. Most piston aircraft are fine on unleaded fuel, except for the higher compression ones requiring the higher octane provided by 100LL.
100ll will not be banned. The EPA will be over ruled. It would devastate the quality of life of so many and will bring down the economy and life as we know it. The lead dispersal in the environment is minuscule compared to what leaded autogas was.
Ethanol in Avgas will be lethal. Fine for dry stable climates but will acquire water easily with devastating results in moist ones. Not to mention incompatibility issues with fuel systems. What's needed is a certifiable substitute for lead.
grate video. I try not to worry about 100LL because i believe their are replacement fuels that are cheaper anyway. AGE85 Aviation Grade Ethanol has high enough octane to do everything 100LL could do and more. and their are some terrific motors out their to get the job done. 100LL is a good fuel. but we can move forward in the future without it. and i think we can do it even with a tight fuel budget. or at least that is what i am hoping for. time will tell, but the future doesn't look that bad.

100 Low Lead is leaded 100 octane aviation fuel for anyone's information...

@ChuckSFP Increase efficiency 4 tines?? Where did you hear that utter nonsense? Go read a book on physics.

@PDZ1122 Try a Chemistry book... I have no idea what Fuel Efficiency has to do with most Physics.

I flew to Rhodesia in the 1950s in machines like that behind you, remember wind pockets..... I do. !

Keep us all updated on whats going on up there! Because it will probably affect the lower 48 too.
