Avgas for Thompson

Testing

At 10% there is no advantage but at E85 there is and the meters we have now cannot tell just how much ethanol is in the fuel that is where the problem is.

George,

Mercury makes the tester we use in the NBRA for Ethanol. It is real cheap. Around $12.00. And it is pretty accurate. Our team has one we use in our own pits to ensure the percentage is within the rules. Makes for a pretty painless weekend, and a whole lot cheaper.
If you want the part number for the tester, I will be happy to try and get it for you.

You are right, E85 straight would be an advatange, IF your engine was set up for it.
