ethanol in gas bad for our cars?

I am about to get some bar and chain lube and put it in my 110 cc mini bike. And the smoke will roll down from the mountain and land up the side of the non coal rollers heads!
Is that thing surging at low cruise, leaning out at idle or failing to re-start hot? :cry:

If not you are probably just wasting good bar and chain lube. :wack:
