Idk if I’m thrilled w the new fuel coming online personally promises promises, heard it before we heard that with ethanol being added to fuel it wouldn’t be any differnt then our fuel lines started disintegrating . That’s bad enough in my boat or my car but I don’t like to mess around w any changes in my airplane . It took some time to see the effects of ethanol too it wasn’t right away . I won’t be flying my kids for a while when the new fuel comes out that is all I know .

I agree with the shelf life issue as well. As for race gas, I have experience with VP, cannot recall exactly which formula, but it did show signs of going bad in an un-opened 5 gallon can within a couple of years...an experience I've never had with 100LL.

As for the new G100UL, all we have to go by is the extensive testing performed by GAMI which far exceeded the FAA's requirements. True, time will tell, but all indications are positive with no ill effects. Whether we like it or not, 100LL is on the EPA's radar as the single largest source of lead emissions into the atmosphere and once approved unleaded aviation gasoline becomes readily available, the EPA will move quick to ban 100LL.

Also, the video link you posted is excellent...never knew the history behind tetraethyl lead and CFCs....thanks!
