    I have been using 87 in everything, but recently went with 89 or 93 in the redmax's and trimmers.

    hello, always use octane rating provided by manufacturer as a minimum ,a higher octane number will give your engine increased resistance to internal detonation and in some cases better fuel economy .
    In a older vehicle 4 example that originally used high octane leaded based fuel that is capable of using current low octane /unleaded and forced to by govt law the DECREASE in performance and fuel economy is HUGE.

    The guys down at my shop told me that I should just use 87 for the mowers, but I should AT LEAST use 89 with the small 2 stroke stuff. ESPECIALLY European or foreign made stuff, the gas they use over there and test all their equipment on is better stuff than ours is (his explanation he told me he learned when Stihl took them all over to Germany or somethin)....
