92 with a splash of 100.. Corn cob fuel will clean everything out of your tank. It will also take any bit of moisture and absorb it into your fuel..

Doug:
Use your 92 for street use and as Kevin said, throw in a 50/50 mix of 100 unleaded race gas for the track.
The ethanol-laced gasolines scour all the dirt and water in the tank and run it through the pump & injectors. Further, ethanol attacks all the (non-Viton) elastomers in the fuel system.
As you know, ethanol doesn't have the same energy content per gallon as gasoline so the fuel mixture goes leaner as well accompanied by small HP drop using that stuff. Ethanol does more for YOU, rather than your car,....

I'm lucky in that the closest gas station to my house has, in addition to the normal 92 w/ ethanol, 92 W/O ethanol and 100 unleaded. Makes the choice easier for local fillups.

thats what I am going to use for awhile (and an occasional splash of 100 in wayzata
(by your house). mk
