virtually all small engines state in the owners manual to only use premium gas, without Ethanol.
Is not advice.
What does your saw owners manual say about fuel?
The owners manual for my 562 XP says:
"Do not use gasoline with an octane grade less than 90 RON/87 AKI." Gas sold at the pump in the USA is rated at the average of the two, so 88.5 minimum. No one reports partial points of octane, so 89, to be safe. That's mid grade gas around here.
The manual also says "Use good quality unleaded gasoline with a maximumof 10% ethanol contents."
I don't run ethanol gas in any of my small engines, despite the fact that most small engine manufacturers say that up to 10% ethanol is OK. Since the only non-ethanol fuel available here (other than the canned stuff - way too expensive) is premium, that's what I buy.
