Hello every one I'm getting ready to take out my boat this weekend but I eat to change my engine oil prior to going. It is a 454 7.4 mpi 99 models and I wanted to know about a oil cleaner? I sell wynns products at my goodyear store and wanted to know if when warming up the oil if I should use a wynns or bg products to help clean the engine??

I wouldn't put any of that snake oil garbage in my engines, I would just change the oil, in my opinion.

Unless the motor is horribly gunked up from somebody never changing the oil and letting it overheat, then there's zero reason to put anything in it other than fresh oil.
