We add 100LL as stabilizer to any gasoline type at 20% of volume. Airplane can sit for 10 years and fuel is still good.
Some smaller piston aircraft are STC'd for 87 Octane. These will last 8-10 years if mixed with 25% 100LL.
100LL is more highly refined, has considerably less lubricity and is anti-microbial in nature-it stabilizes itself.
Any non Av grade gas begins to break down on day 2 with exposure to the elements, mainly O2. Moisture plays a part as well, microbials live in car gas and Kerosene, over time it grows algal organisms and sours quickly. I'm getting too deep here :-))


Thanks!! So if that's the case, then they have to re-refine it to get the lead out if the gasoline were ever to be used for the general public?

I run 100 LL in my chainsaws and have 0 issues, no matter how hot or cold it is out, and I also don't have to worry about ethanol either.
