I have used Wal-Mart oil for years ( since the late seventies) and never had a problem. I have never owned an oil injection motor however, and have mixed oil since my teenage years on both my boats and my dad's many years ago. My brother mixed oil once back in the seventies and blew my dad's Johnson 120 HP. He blamed it on the oil we were using, but I think otherwise.

I've used Quicksilver Oil in my oil injection 01 Merc since I bought it without any problems. I did also just find some wood and gave it a pretty good whack.
