Re: First run today!
The opposite can be true if using some air cooled oils in an outboard. If the oil can't reach its design operating temperature it can clog critical oil passages in the crank and connecting rod bearings. That can be as bad as the oil breaking down. This isn't a myth either. I've seen outboard engines ruined from lack of lubrication and clogged oil passages was the culprit.
