OK Tracy, Ed, Anyone,
Have you investigated running high energy coils for a better spark to avoid SAG? Racing rotaries have run endurance races running all sorts of "moon gas" with minimal problems. They don't usually run as long as you are talking about. (20 or more hours) The racing fuel is almost always highly leaded fuel to provide high octane. While helping with several cars we never had this problem. Does anyone know if Mazda ran an unleaded fuel in the LeMans effort? Almost all the car guys run MSD iginitions of some type. I know Lynn id running MSD in his car. While building racing motorcycle engines I checked out the Saab Turbo ingition with Ferrofluidic (Superfinely ground iron particles in supension) Coils. A really neat sustem with a single coil at each plug. The 4 LS-1 coils should do the same thing though.

I have only used auto gas , but will not hesitate to use 100LL if auto not convenient on long cross country. I added 24 gal capacity to my 9A to keep from buying as much 100LL.
For some reason it seems like Tracy said the A/F sensor also lasted longer on auto same as spark plugs.
