Here is a new aircraft fuel.
http://www.swiftenterprises.net/Swift%20Fuel.html
As a Purdue Engineering grad I have some contacts there.
I can probably get a tankfull or two of this new gas.
Since my new Carbon Cub will be delivered as an ELSA I would not break any FAA rules if I burned Swiftfuel in the CC340 engine.
The fuel has a motor octane rating of 104 and 15% more energy density.
It also weighs 6.5 lbs/gal.
Anyone at CC or elsewhere have comments or a problem with this??
