i use 87. i believe there is 10% in each grade. ethanol does make more power but takes more of it to produce it. just dont use e85.

Use the highest octane of the best name brand. Don't cheap out.

Gas is exspensive, but your machine will thank you for buying the highest grade gas possible without ethanol. Its getting harder to find non ethanol gas, but with the help of the internet .....

Ethanol sucks...

I don't know of a gas station around here that doesn't have ethanol in their gas. I have a 2005, the manual says 91 or higher. Most stations around here are 87, 89 and 93 so I use the 93. And, compared to filling up my truck, it's cheap!

air cooled engines can run very hot (and the tendency to cool unevenly, leaving hotspots in the cylinder walls at combustion chamber), which can cause pinging and knocking (which can damage your engine). Higher grade/octane fuels mitigate knocking. It's pretty simple: use the high octane gas to prevent potential engine damage.

Ethanol cause gas to turn to snot and gum up carb much quicker (months).

Here in Wisconsin, KwikTrip sells premium without ethanol in it. I run it in my Blast and anything that might sit for a while like lawn equipment.
