Is it better for an old engine in my wood chipper to use the recommended 90 octane even if it’s 10% ethanol? Or 87 octane ethanol-free?

    Thanks for the link. There’s only ethanol free 87 available unless I get 110 from a specialty shop for about $9/gallon. I use up to 20 gallons a week so that would add it up quickly.
