All the new fuels planned will be acceptable for use in 99% of engines already out there. At least that is what we are suppose to believe. It's a big deal to make an alternative that the FAA will stamp for a certified airplane. It takes a ton of testing and due diligence on the part of the STC holder to make these mods acceptable.

The area that I am concerned with is the cost, there is already an established price out there and it's damn expensive for 100LL. You think this new fuel is going to be cheaper? I am not encouraged to think so, why would it, we are already paying the price. When it comes down to it we have some very expensive trophies in our hangars.
