So I just bought my first engine, it's an 80 cc 2-stroke from PowerKingShop on eBay. It says to use # 90 gas. I'm assuming that means 90 octane level...

What about ethanol? Should I or should I not use ethanol in this 2-stroke? What kind of gas do you guys use for your 2-strokes (regular unleaded, super unleaded, etc, etc)?

Thanks much!

High(er) octane burns more slowly. Our China in frame bicycle engines have very low compression and don't need anything more than the lowest octane.

Long story too short- use unleaded regular- 87 octane around here.

Octane ratings are measured differently in different areas of the world and the "90" mentioned in the "instructions" probably equates to about an "85" here so regulat is fine. Less ethanol the better, but most places hace at least 10% (around here).
