Perhaps the comparison test was about performance.  I'll wait and
    see what
    he says.   AGE-85 is formulated with aircraft in mind, using many of the
    performance enhancing additives that gasoline normally has including
    a wee
    bit of biodiesel, whereas Baylor's E-95 (at this point) is just
    denatured
    ethanol.  Don't race cars run on methanol?

Doug,
 Yes racecars usually run Methanol, which is even worse energy wise.
Simple fact is gasoline comes in at 115,000 BTU/gal and ethanol at
84,000 BTU/gal, or about 73% the energy available in a gallon of
gasoline. Gas is hard to beat. Some of the effects of burning ethanol
may help bring it closer to gasoline. Tolerance of higher compression
without detonation or per-ignition, and less thermal energy wasted to
cooling do help, but ethanol comes in with a large gap relative to
gasoline. It's a cleaner burning fuel but you can't make the physics
change much. The rotaries tolerance for a wide range of fuels is useful,
but spark ignition bio-diesel might do you better for milage.
Bill Jepson

Spark ignition bio-diesel is a new one on me. Please explain. Do you
mix it with gasoline, and if so in what ratio?

#2 diesel has much more energy than gasoline. The biodiesel I am
familiar with has slightly less, but still more than gasoline.

CW and perhaps John
The Wankel will run on direct injection diesel fuel
as long as you fire it with a spark plug.

CW and perhaps John Deere were running the engine on heavy fuel
years ago. there are many SAE and other tech papers on the subject.

Wankel Gmbh demonstrated such a turbo charged engine at OSH
several years ago. Here are some pictures from the factory
in Korf Germany

Mistral in Geneva Switzerland is/was also working on a
NA such engine. Here are some pictures of the engine
on the Mistral dyno in Geneva.
