Is there a benefit to higher octane gas in yard equipment?

89 or 91 octane instead of 87? Mowers, edgers, and the like?
Always non-ethanol of course.

No

Not unless it's the recommended minimum for that engine.
If the engine doesn't have a high enough compression ratio to need higher octane, there's no advantage.

I thought non ethanol is always the highest octane %

Higher octane doesn't go stale as quickly. In better fuel brands the higher octane fuels contain more detergent additives. I've always run at least mid-grade which is recommended by some equipment manufactures as a minimum.

No, I've never heard of a mower or weedeater that required higher octane gas.

Octane rating or octane number is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). In broad terms, fuels with a higher octane rating are used in high performance gasoline engines that require higher compression ratios.

I always use no ethanol premium, just because. The stuff seems to last longer than it did when I used regular gas station gas.

Read a Stihl owner's manual.

dang...where are ya'll seeing 91 and 93 no ethanol?
I can only find 89...
Of all the two stroke enduro's I owned back in the day...93 octane always ran the best...it never hurt to throw in a little av gas or VP racing fuel once in a while either...

No, not good to do on a regular basis?

Don't forget to use stabil.

Unless the engine has a higher compression ration which makes it a necessity, it is a waste of money.
During the hottest months, I will run an oz or so of 2 cycle oil per gallon of gas. It helps lube the intake valves a little better. Typically shows a few degrees drop in temperature on the motor as well.
It would likely run perfectly without my additions, but I like tinkering with things that aren't broken.

Not for those engines. They aren't built very well in relation to a car or motorcycle engine. But ethanol free is a benefit.

nope...the only reason you would need higher octane is if the engine was detonating...and I have never heard a small engine detonating.
the only time that I think it would be conciveable would be if carbon had built up in the cylinders to the point that it started detonating...and then I would just flush some seafoam through the intake to knock out the carbon.

Most high end equipment like Stihl, Shindaiwa etc require 89

Higher octane fuel ,doesn't degrade as quickly. That generally helps in lawn equipment.
End of season, fry to run some Stabil through it and drain the tank.

This and no ethanol and you will be fine

Just go ahead and admit you pulled this out your arse

You just go ahead and research fuel additives and what makes up gasoline's octane rating.
