You’d normally see AV gas rated at 100 octane. You might run into 130 for rich running engines and heavy load take offs.

“You’d normally see AV gas rated at 100 octane. You might run into 130 for rich running engines and heavy load take offs.”

If you run into 100 octane you have also run into 130 octane.

It is the same gas. Just rated differently at different mixtures.

100LL is the standard.

100 is plenty good for small/older engines. I’ll look into getting some for around here.
