Higher octane gasoline has a higher ability to resist spark-knock (detonation). Higher octane gas also burns slower. Higher octane gas isnt going to hurt your 2-stroke gas engine. 2-stroke engines tend to perform better on higher octane gas anyway. I use premium/high octane in all of my small gas engines.

You want to use a good high quality oil for air cooled engines. Do not use oil designed for an outboard engine, which is water cooled.

I always add more oil to break in a new engine. For a gas 2-stroke, I would break it in on 20:1 mineral oil and for normal operation I'd run 25:1-32:1 synthetic oil. The extra oil in a cramped R/C car engine isnt necessarily a bad thing so to be safe, I'd run the recommended 25:1 after break-in.
