A local small motors shop is reccomending people burn aviation fuel in small motors I was recently told.

That's interesting.

I have been experimenting I put some mid grade in my small equipment this time and oh my goodness I'm sold the higher octane burns hotter and warms the engine faster :)

Here premium is only 91 octane. I like it. I like it even better if it is the non ethanol 91. I still use some kind of fuel stabilizer. It does not seem to hurt and I think helps. I use Stabil, Briggs, MTD, about any kind. Stabil the last two years. The old timers here all use Seafoam. I do not know what kind of guys miss spell fuel. I do know what kind of guys make a big deal of it.

We buy Sunoco gas, here the premium is 93 octane. Never used any stabilizer, I don't keep gas long enough for that stuff and do to the fact I run four different mowers a day I can't afford the stuff. The ethanol is something that has never been an issue for me in any of my mowers or equipment. I take that back, I replaced all the gas caps on my Stihl equipment through a Stihl Recall, they said the rubber seals were going bad do to the ethanol gas and that didn't cost me anything.

That particular shop is probably one of the older shops in this area. They have been in business since the 1970's.
 
I just bought a new machine the owners manual states use 87 octane and up , iirc. You WILL get nasty backfires running low octane I bent valves on one engine with that crap. Since , I've run all my small engines on 91octane. I haven't had a backfire since.
I used to mix race gas into my portable tank mixed with 87octane but its expensive. Octane matters especially in the heat. Cold air you can run lower octane.



87 octane is for feuls. :laughing:
