The Mercury 4 Stroke 25W-40 Mineral Blend 1L Oil is specially formulated to protect and extend the life of Mercury four-stroke marine engines. With a robust mineral blend base and additives tailored for the marine environment, this oil ensures your engine performs at its best through every trip.
Built for Four-Stroke Marine Engines
Unlike standard automotive oils, marine engines require oils that handle high loads, extended running hours, and frequent exposure to salt and moisture. The Mercury 4 Stroke 25W-40 Mineral Blend 1L Oil is engineered to meet these unique demands. It maintains viscosity even under high temperatures, providing consistent lubrication during long idle periods and high-RPM operation.
Protects Against Corrosion and Wear
This oil is infused with advanced corrosion inhibitors to combat rust and oxidation caused by marine conditions. It forms a strong protective film on internal engine parts, reducing metal-on-metal contact. As a result, it prolongs engine life, minimises wear, and supports smoother performance season after season.
Clean Performance You Can Rely On
Carbon buildup and sludge are major enemies of engine performance. Fortunately, this mineral blend helps reduce both. It keeps internal components cleaner, leading to better combustion, easier starts, and improved fuel efficiency. The clean-running formula also means fewer deposits and longer intervals between maintenance.
