Default New GAMI no-lead fuel STC

Will experimental need an STC? Rotax? Or can we just buy it and use it?

Default NO

Do you need an STC for any other change you make? STC is a Supplemental Type Certificate, The RVs don't have a Type Certificate to be suplemented.

No STC needed for G100UL, nor any other fuel for experiment airplanes. In fact… STCs aren’t needed for anything in experimental aviation.

Not everyone knows this, and I wouldn’t be surprised if some education might be needed for ramp workers and other FBO personnel when you go to get your airplane fueled if-and-when G100 comes to an airport near you in the next couple of years.

While experimental aircraft do not need an STC for unleaded fuel, you will likely need to update your POH and fuel labeling on/near the fuel caps.

Yup. If-and-when.

I’m thinking something like “Avgas… 100 octane“ or similar.

The data plate on my O-360 A1A says, "Min octane 91/96".
That's what the label next to my gas caps says.

Just as a clarifying point, experimental aircraft are not required to have a POH either. Labels on fuel caps, yes.

Updating and printing a new POH for me is about a 2 minute MS Word exercise.

As to gas caps, I guess more generic is better. I’m thinking “AVGAS 91 OCTANE MIN” ought to cover it.

Up North Engraving is apparently not engraving gas caps any more. I’ve looked over Bill’s…no online ordering or credit cards but he’ll supply new top-plates-only for $32 each. Who else does that engraving?
