It’s always a good debate on here… ethanol vs non-ethanol.
In general, small engines like non-ethanol. Not because it runs much different, but it can sit longer without varnish. Some members report better results with non-ethanol. If you run the machine regular, it really won’t matter much. I typically run non-ethanol premium. If it sits for 6-8 weeks, it doesn’t give me any trouble. Try both, and share your results.
Ditto.. I tun 91 octain in the Kodiacs. Can't say I can tell a performance difference from 87 with ethanol. However the reason use 91 octane without ethanol is for the superior starting in all of my small engines (Stihl chainsaws, etc) and non ethanol here requires 91 gas. This is primarily a benefit on starting especially if the engine is not started often. Nothing infuriates me like a chainsaw that resists starting reliably and leaves one exhausted even before getting work started. Easiest to keep all gas cans with the same fuel.
