Lower unit gear oil serves as the critical lubricant for one of the most demanding mechanical systems on any vessel. In contrast, a straight 90 gear oil is a single-grade fluid that maintains a consistent, thicker viscosity ideal for warm-weather operation or vehicles that consistently run at high loads.
Mineral Oil Lower Unit Gear Choice: Selecting the Right Viscosity and Additives
Using the wrong viscosity can lead to inadequate lubrication or excessive drag. Single-grade 90 oil provides maximum film strength in consistently warm environments.
Mineral Oil: Making the Right Choice. Multi-grade options like 80W-90 offer superior cold-flow characteristics for easier starting.

Extreme Pressure (EP) additives are crucial for handling the shock loads and sudden direction changes common in boating, while rust and oxidation inhibitors protect against the corrosive nature of water intrusion. Always consult the vessel's owner manual for the manufacturer's specific viscosity recommendation.
