The Mercury Synthetic Blend 10W30 1L Oil is engineered to provide dependable, high-quality lubrication specifically for marine four-stroke engines. It’s formulated to endure harsh marine conditions, making it an ideal choice for boat owners who expect peak performance and long-lasting engine protection.
Premium Performance You Can Trust
Designed to meet Mercury Marine’s rigorous standards, this oil blends the thermal stability of synthetics with the trusted reliability of mineral base oils. The result? A robust lubricant that reduces engine wear, maintains clean internal components, and delivers consistent power in high-load marine environments.
The Mercury Synthetic Blend 10W30 1L Oil resists breakdown at high operating temperatures and maintains proper viscosity in both hot and cold weather. This means reliable performance whether you’re cruising under the summer sun or starting up on a chilly morning.
Clean Engine, Longer Life
This synthetic blend minimises internal deposits and sludge, helping keep engine parts clean and well-lubricated. A clean engine doesn’t just perform better—it lasts longer. You’ll also enjoy smoother operation and improved fuel efficiency thanks to reduced friction and superior lubrication across all moving parts.
Designed for Marine-Specific Conditions
Unlike automotive oils, this marine-grade oil includes additives that protect against moisture, rust, corrosion, and foaming—common threats in saltwater and humid environments. These protective features help extend engine life while reducing the need for frequent maintenance.
