Correct. It is a corrosive add on that eats small engines alive. Plastics are the norm in small engines and they hate the stuff.
Go to Home Depot and get 100% gas in a can for small engines and thank me later.
Not arguing with you on this at all... But I'm going to add...
Look to get cans from unopened cases or from the back and find out if the store accepts returns on the stuff. I've read (I think on this board) of folks buying cans of water that had been returned.
I know they sell it in both pre-mixed and no oil varieties. I've never had (might be jinxing myself) a problem in my larger small engines. Usually it's just your two stroke motors in my experience that can't handle the stuff. I use the caned stuff in all of my 2 strokes, but not in my larger 4 stroke mower.
