Mercury Mercruiser TDI Diesel Oil 3.78L (8M0069602)

The Mercury Mercruiser TDI Diesel Oil 3.78L is formulated to deliver high-performance lubrication for modern marine diesel engines. Specifically developed for Mercury’s TDI (Turbocharged Direct Injection) platforms, this oil helps your engine perform reliably—even under intense loads and long operating hours.

Designed for TDI Marine Engines

TDI engines work harder than most, so they demand oil that can keep up. The Mercury Mercruiser TDI Diesel Oil 3.78L provides excellent wear protection and thermal stability. It reduces friction and helps control soot, keeping your engine cleaner and running stronger. Whether cruising or towing, you get dependable lubrication every time.

Outstanding Heat and Soot Control

Diesel engines produce high heat and carbon. This oil resists breakdown in high-temperature environments. Moreover, its advanced detergent package helps manage soot and keeps sludge to a minimum. That means your oil lasts longer, and your engine stays efficient and clean.

Built for Marine Conditions

Saltwater, humidity, and idle-heavy usage can take a toll on marine engines. That’s why this oil includes corrosion inhibitors that protect key components. It forms a protective film that defends against rust and metal wear—even during storage. You can rely on it through every season.

Keeps Maintenance Simple

Using the right oil helps you avoid unnecessary repairs. With fewer deposits and consistent viscosity, your engine remains in better shape between services. Plus, smoother running means fewer performance issues and more hours out on the water.

Ideal 3.78L Size

This 3.78-litre bottle is the perfect size for oil changes or top-ups. It features a sturdy handle and spill-resistant cap for easy pouring. Keep it onboard or in your maintenance kit so you’re always ready for quick servicing.
