Lycoming O320-D2G in a Skyhawk. Thanks in advance.

Can you get the autogas STC for that engine?

We had the O320 in our Warrior, and unleaded autogas completely eliminated
failed mag checks, and the need to lean over-aggressively.

No, the D2G engine is higher compression and requires 100 octane. The
upside is you get 10 more horses (160 vs 150).

Maybe just as well to not mess with autogas out here anyway. Flying in
the nearby mountains can require climbing to 13,000 feet or higher, and
I've heard auto gas is more prone to vapor lock at high altitudes. I'm
no expert though, and haven't done any further research since it's a
moot point for my plane anyway.
