This is my second time using this oil to service my 2022 Mercury 90 outboard. Excellent oil! Engine runs extremely smooth. The jug was very easy to pour from. No smoke from the engine.

Oily situation lol

Honestly how do you write a review of this product? I would have to run tests for years on multiple oils on various engines to do so. The value was good however and shipping was great
