I was buying ethyl I guess. Ran like nitrous, much colder. Carbs would frost up late in the day.

Looks like the green must be unleaded. I always go for the highest grade at the pump when I go to the airport to buy fuel, and 100LL (100 octane low lead) is usually the highest grade.

I’ll need to have a look when I go next time, and see if they have the unleaded.

Thanks Cliff.

So this site lists, but doesn’t really describe the differences in the green and blue dyed 100 octane avgas. I did find a Shell avgas site that does.

So the green dyed avgas is an older formulation that has tetra ethyl lead in it, and the blue dyed avgas has a lower amount of lead in it than the green dyed fuel, hence, the “LL” designation.

Sheesh, I learn something new everyday.
