Motul Outboard Tech 4T 10W-30 Technosynthese Marine Engine Oil 2L
Motul Outboard Tech 4T 10W-30 is a Technosynthese marine engine oil developed for gasoline-powered 4-stroke outboard and sterndrive engines requiring an NMMA FC-W lubricant.
Its marine-specific formulation provides strong oil-film protection at high operating temperatures and helps compensate for fuel dilution caused by prolonged idling. It also delivers enhanced corrosion protection against moisture, seawater, and saltwater exposure commonly encountered in marine environments.
This package includes one 2-liter bottle for compatible boats, personal marine applications, seasonal maintenance, and routine outboard-engine service. The 2-liter configuration is associated with manufacturer part number 101745.
WHY THIS OIL:
The Technosynthese formulation combines dependable engine protection with strong resistance to oxidation, thermal stress, and viscosity breakdown.
Its higher oil-film resistance supports protection during sustained high-temperature operation and helps manage the effects of fuel dilution during extended low-speed running or idling.
Enhanced anti-corrosion performance protects internal engine components against moisture, seawater contamination, and saltwater fog entering through the exhaust system.
Strong shear stability helps maintain the protective SAE 10W-30 viscosity throughout the service interval.
Anti-foam properties help prevent air bubbles from entering the lubrication circuit, while anti-clogging performance supports oil-filter cleanliness.

FITMENT AND COMPATIBILITY NOTE:
Use only in compatible gasoline-powered marine engines requiring SAE 10W-30, NMMA FC-W, API SJ, or API SG engine oil.
The listed marine-engine brands do not mean this product is suitable for every engine produced by those manufacturers. Verify the exact engine model, model year, required viscosity, oil capacity, and service specification before use.
Do not use in 2-stroke marine engines, diesel engines, or applications requiring a different viscosity or lubricant standard.
This product is engine oil and is not intended as a substitute for sterndrive gear lubricant, lower-unit oil, hydraulic fluid, or power-trim fluid.
IMPORTANT NOTES:
Follow the engine manufacturer’s specified oil-change interval and adjust it for saltwater use, prolonged idling, frequent low-speed operation, fuel dilution, seasonal storage, or severe service.
This lubricant can be mixed with compatible synthetic or mineral engine oils, but a complete oil and filter change is preferred when changing products.
Check the engine-oil level before each outing and inspect the used oil for evidence of water contamination, fuel dilution, or abnormal discoloration.
Store tightly closed in a clean, dry location protected from moisture, contamination, and extreme temperatures.
