87 or 89 octane?

[cfelton]

Here in NC we can still buy E free. Most gas stations sell 89 octane. I go to a couple of places and fill all my jugs with 93 E free. Since I still run a 170 Mercruiser inboard thats what I run in it. I don't put ethanol in anything but my pickup trucks. Lawnmowers, weed eaters leaf blowers, and tillers get 93 octane non ethanol. I work on alot of small 2 cycle engines and ethanol will ruin the carbs on small 2 cycle engines. Ethanol is the worst thing thats ever come out. I run 93 ethanol in my 97 Tacoma with 4 ozs. of Lucus injector cleaner every tank full. It just tripped 431000 this morning and still runs perfect.
