Installed product in my 2008 Mercury 90 hp efi outboard engine . Engines runs smooth and has been for a full season here in Florida. No complaint and will continue to use. Usual season is about 150 hours of run time under various speeds .Check engine oil level before each trip. No unusual usage or color.

You can't beat the price of this oil, especially how other brands are double the price for synthetic blend. I've used this for 3 seasons so far without issue.
