I had diesel in a red can for my JD Skid Loader. I have a husqevarna riding mower with a gas engine. I could not believe how much smoke rolled out of that thing before it quit running. Drained out the diesel and refilled with gas and a couple minutes of thick smoke later all was good. I knew just who to blame it on as I see him every day in the mirror. That was 2 years ago and the motor is still running fine. But I felt pretty stupid at the time.
