Liqui Moly Marine 4T Motor Oil - 15W40 - 1Ltr

This oil is designed for 4-stroke marine engines. Always verify that your specific engine requires an SAE 15W-40 viscosity grade and meets the recommended API service classification, often referenced in your engine's owner's manual.

TC-W3 is a standard established by the NMMA (National Marine Manufacturers Association) for two-stroke and some four-stroke marine engine oils, indicating a certain level of performance and lubricity. While this oil is 4T, it meets this standard.

No, this is a 4-stroke engine oil. Using it in a 2-stroke engine can cause significant damage. Always use the correct oil type specified for your engine.

Refer to your marine engine's owner's manual for the recommended oil change interval. This typically depends on engine hours and operating conditions.

Biodegradable oils break down more easily in the environment, reducing the long-term ecological impact of potential spills or leaks compared to conventional oils.

Store the oil in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the container is tightly sealed.

Check oil level when the engine is at operating temperature and on a level surface. Top up with the correct grade of Liqui Moly Marine 4T Motor Oil if necessary. Frequent low levels may indicate a leak or oil consumption.

While this oil is low-smoke, excessive smoke can indicate other engine issues like worn piston rings or valve seals. Ensure the oil is not being overfilled and consult your engine manual or a marine mechanic.

This can indicate water contamination. Check seals and gaskets for leaks. If water ingress is suspected, the oil and filter should be changed immediately, and the cause of the water intrusion investigated.
