Do you use 87, 89, or 93 Octane in your Lawn Equipment?
all my stihl stuff I use 93 oct.. for my mowers and other stuff 87 oct. I use stable in all my gas! just because I do know when I uses them from time to time.
I use 93 in my Stihl, Echo, and Redmax gear...and 89 in my mower.
I use what the owner's manual recommends.
I have been using 87 in everything, but recently went with 89 or 93 in the redmax's and trimmers.
Have been using 87, old stihl blower was getting hard to start so switched to 93 for everything now.
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.
I try to use 89 in everything.
112 octane Sunoco at $8.75 a gallon is the way to go!!!!
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)....
