Do you suspect you will save money with autogas? When I had the Aeronca
my experience was that unless you brought it with you, auto gas was
almost as expensive as avgas at the airport. Factor in having to go out
of your way to find it, it wasn't worth it.
However, I will say that the 65hp Cont. engine ran much better on auto
gas. The solvents in car gas seem to really keep the engine clean and
the lower octane helps a lot too.

Sadly, I live in California where almost all autogas is illegal
according to the STC. The EAA says there are no plans to get approval
for "modern" gas. Let's hope they change the formula again.
