Just saw this while getting gas. Why is it illegal to get less than 4 gallons? - Lemmy.World

Which is it, up to 15% or up to 10% ethanol?
It’s 10% in the winter and 15% in the summer (at least that’s the legal limit), although I think that’s changing. So I guess they just said what the hell and put on both stickers?
Where I live you can get zero percent and even leaded gasoline…
Woah. I didn’t know leaded gasoline was still available anywhere.

General Aviation fuel (think propeller planes) use Avgas still uses tetraethyl lead, which is “leaded gasoline”.

They’re trying get rid of it, there’s a phase out target of 2030 for piston aircraft. Turbines jet engines already use different fuel.
So there’s a shit load of caveats. One there’s only a few places i know in the state that sell it. It’s supposedly only for small engine purposes, and it’s illegal to pump into a car. There’s daily limits imposed by the gas station and weekly and yearly limits imposed by the state I think, but I never looked them up.
