i run 93 with 20cc domes. thought about 110 octane but it is expensive!!

[bansheejoel]

Fuel octane goes by compression and timing......your low enough on compression and timing

pump 93 with the occassional booster

If you need race fuel, then use it. It may be expensive, but an engine is more expensive. Detonation will kill a top end, quick. bansh-eman, fouldout, locogato, and a few other guys that are extremely experienced 2-strokers can tell you the formula for figuring your compression ratio. That is what you need to know when buying fuel. Don't use octane booster. It's not consistant. And just to add to bansheejoel's post, also goes by altitude.
