OEM recommended.
Style: Mineral, Pattern Name: Quart - 1 Pack
It is the OEM recommended oil for my 2017 9.9 outboard. Arrived quickly and in a sealed plastic bag. No leaks. This is 32 oz and the motor only calls for 27 oz so enough for topping up in needed.

Great for Mercury 4-stroke outboard
Style: Mineral, Pattern Name: Gallon - 1 Pack
The price was too good to pass; I stocked up on 3 years' worth of oil. QuikSilver is OEM Mercury oil, and this stuff has long shelf life if you can store it in stable indoor temperature/away from temperature extremes. Great buy overall, highly recommended.
