Possible no-ethanol test for you - Aviation gasoline. It does not contain ethanol Ethanol is prohibited in aviation gasoline, although some aircraft have a cert to run auto gas. Try to get the lowest performance number available so you don't cook a valve.
Couple of problems though - May contain lead (bad for catalytic converter) and is pricey - about $4.50/gl for 110LL. May work if your test vehicle is too old to have a converter.
