How does Mercury 10W-30 4-Stroke marine oil protect my outboard during summer or high-rpm use?

Mercury 10W-30 4-Stroke oil uses a marine-specific additive package that helps preserve viscosity and lubrication when engines run hot or at higher RPM for extended periods. It includes corrosion inhibitors to guard metal surfaces from saltwater exposure and storage-related oxidation, helping components last longer.

• Viscosity retention under heat and extended high-rpm operation.
• Additives that reduce wear and maintain lubricity between oil changes.
• Corrosion inhibitors tailored to protect parts exposed to marine environments.
