hmmm, i run 87 octane gas...don't really care if it has ethanol in it or not.
I just get whatever's cheapest, and i get it at the same time that i get gas for my mower.
I run whatever 2 stroke oil that i happen to stumble across when i'm out shopping and i remember that i need to buy some.
I've ran the supertech oil, gumout oil, pennzoil...whatever i can get.
I run the mix at 32:1 most of the time, sometimes at 40:1.
I'm not a perfectionist when it comes to my fuel-oil mixes and ratios.
it seems to run the same, no matter what oil i use.
