Frequently Asked Questions
What is TCW-3 certification?
TCW-3 is a performance standard established by the NMMA (National Marine Manufacturers Association) for 2-stroke outboard engine oil, indicating it meets specific requirements for lubricity, cleanliness, and protection against wear and corrosion.
Why is direct injection oil important?
Direct injection engines inject fuel and oil separately into the cylinder, requiring specialized oil that burns cleaner and provides superior lubrication under higher pressures and temperatures compared to pre-mix oils.
What is the maximum engine size for this oil?
This Dometic TCW-3 oil is suitable for 2-stroke outboard engines with horsepower ratings up to 75 HP that utilize direct injection technology.
How does this oil protect the engine?
It provides advanced lubrication to reduce friction and wear on critical engine components, while its formulation helps prevent carbon deposits on piston crowns, rings, and exhaust ports, ensuring efficient operation.
What is the shelf life of this product?
Properly stored in a cool, dry environment away from direct sunlight and extreme temperatures, this lubricant typically maintains its efficacy for at least 2-3 years.
