That's what it says in my Sthil books.

I buy gas for my mowers and handhelds at the same time. Being Sthil wants 89 octane because their air cooled engines will run cooler. Being my mowers are air cooled they will benefit from running on 89 as well. So I that is why I use 89 in my mowers and all the other equipment that I own.

Auto's get 87 octane.

This is what the manufacturers call for, so that's what I use. Oh, yes, it's also ethanol free gas, and at least so far have eliminated gas related problems I used to have.

Absolutely no reason to put anything other than 87 in mowers unless you want to get 100% gasoline and premium is the only way to do that where you live. Compression is not high enough in these motors to require anything greater than 87. Definitely smart to put 89 in handheld mix especially 100% gasoline to avoid dumb carb problems on them.

I usually put 87 in the mowers and handhelds but after reading what these guys use I'm going to try 89 for the handhelds.

I think it is a 230 and it has been going about 6 or 7 years now with no air filter. I used it today actually. We did all our monday lawns today because they are calling for torrential rains tonight and tomorrow and off and on rain all week. It doesnt even have a primer bulb. Flip the choke on and crank it two or three times and it fires right up.
