Performance & Practical Benefits

What riders notice first with this oil is how composed their engine feels once it’s warmed up. High-rpm runs stay smooth instead of sounding strained or dry. The oil holds its viscosity, even when temperatures climb on long summer rides or slow-moving trail sections. That steady oil pressure makes everything feel more controlled — from acceleration to downshifts to steady cruising at speed.

The wet-clutch compatibility is another major advantage. Some oils can cause slipping or delayed engagement, but this formulation keeps the clutch feeling tight and connected. It delivers that precise, predictable response you rely on when navigating traffic or working through a technical trail. Over time, its corrosion protection and low volatility help extend engine life, reducing oil consumption and minimizing internal wear. It’s the kind of oil that quietly works in the background, giving you confidence in your machine even after long periods of storage or sporadic weekend riding.

Why Buy OEM

Quicksilver’s full synthetic blend is engineered with the same high standards the company applies to its marine engines — systems that run under extreme load, heat, and stress. That level of research and testing means you’re getting oil that performs consistently in real-world riding conditions, not just in a lab. It meets strict performance certifications, won’t void manufacturer warranties, and is trusted by riders who care about long-term reliability. Choosing this Mercury Marine part number is simply the practical move for better protection, smoother performance, and peace of mind mile after mile.
