What octane gas do you use in your 2 stroke

I use 93 octane most company's recommend 92-93 and I use amsoil 100 to 1 mix at 2.6 Oz's to a gallon (50 to 1).

All of my Shindaiwa and Stihl manuals call for 89 so that's what I use. I put 87 in the mowers and truck.

I use 93 from either BP or Exxon only. We have trouble in 90 and above temps with string trimmers not starting on other brands. Mostly vaporlock, trimmers are hot and fuel evaporates.

Same here. Echo manuals call for 89 octane also.

87 with opti 2. Even has 10% ethonal. No winterization, starts fine each spring for the last 8 yrs. I have yet had any issues with my 2 strokes. Just one primer bulb on a 9yr old handheld blower, and one exhaust port cleaning on a trimmer. Going to do the exhaust port cleaning yearly now though.

I have been running 87 in my handhelds for 10 years without a single problem ever. In fact i have an old shindi eb630 blower thats atleast 10 years old and still starts up 2nd pull have never run anything but 87 in it. I also have 3 stihl fs80r trimmers that are atleast 6-7 years old that i still run daily with no issues what so ever.

For several years I was running all of my trimmers and blowers with 87 octane fuel. Just this year I started to use 89 octane fuel and have noticed that my stuff would start easier. The last time I filled up my mix can for my trimmers/blowers I used 93 octane Shell V-power. We'll see how things go with that.

Cheap stuff here, same that the mowers get. I tried the higher grade and noticed no difference in my trimmers and blowers; chain saws however it made a difference.

So for the summer 87, and winter 93. I'm one of those people that doesn't care what the manuals say, I'm going to run whatever the equipment seems to be the happiest on; same reason I run 15-40 Shell Rotella in all of my mowers.

I use a 50/50 mix of E10 87 & 100% gas 92 octane for a only half as evil blend of E05 I also put a touch of StarTron and isopropyl alcohol in the mix.

I was under the impression that using a higher octane than necessary will leave unburned deposits in the combustion chamber. In a 2-stroke this may be be splitting hairs.

Maybe I should just use the pure 100% gas at 92 octane for 2 strokes and be done with it already....?
