Worked for Me!

I ran non-ethanol plug with 91 octane & ethanol in the gas at 9K-12K with no problems. I did run marine grade stabil with every tank of gas though.

I run the exact same setup with no detonation. It depends on elevation. If I dip below 8500 ft, I swap back to the ethanol plug for good measure.
