E15 Gas Introduced, Car Mfgs Warn Not To Use It

My cardlock dealer just tried to say that I had been fueling with ethanol free fuel and had to refund me $.30+ a gallon. I don't think that I'll be using them any more.
I just got a can of gas for my lawn mowers,riding and push, and I think I'm going to have to go back and check the pump as both of them aren't running at all right.
I also just bought a couple of new cans and they are really a PIA to use. Gonna go back to my old ones. Hate those spouts and they leak bad when you're pouring.
