Even during long, wide-open runs, it holds up beautifully. The synthetic blend resists breakdown under pressure and temperature swings, keeping your internals free from sludge and varnish. Carbon stays low, performance stays high, and you get to spend more time doing what you love — exploring open water without worrying about your motor.

Why Buy OEM

When you buy genuine Quicksilver, you’re buying the same formulation Mercury Marine engineers designed to protect their own engines. This isn’t a “universal” oil that kind of fits everything — it’s a precise blend built for real-world marine performance. Every drop has been tested under full load, salt spray, and long idle conditions.

Using OEM oil means no guesswork, no risk. You’ll get consistent results, longer service intervals, and fewer mechanical surprises. And honestly, that’s what boating’s all about — less fixing, more fishing; less tinkering, more time out on the water.
