Liqui Moly Marine 4T Motor Oil 10W-40 is a modern low-friction engine oil based on synthetic technology, specifically developed for marine and maritime applications. It provides excellent wear protection, outstanding engine cleanliness, and reliable lubrication under the demanding conditions found in marine environments. Formulated with a high level of corrosion protection additives, this oil protects internal engine components against moisture and harsh operating conditions. Rapid oil circulation ensures dependable lubrication during cold starts, while stable performance is maintained across a wide temperature range. Suitable for petrol and diesel 4-stroke engines, with or without turbochargers, it is also tested for use with catalytic converters and turbochargers.
