Outboard Oil TCW-3 represents the culmination of an evolving lineage of lubricating oils, meticulously designed to address the evolving demands and heightened rigor of water-cooled outboard engines. This advanced formula adheres to the NMMA (National Marine Manufacturers Association) TC-W3 Recertified oil standard, ensuring its compliance with the industry’s highest quality standards.

Outboard Oil TCW-3 provides unparalleled protection, catering to the demands of modern high-temperature outboard engines. Its versatile formulation also delivers exceptional performance when employed in two-stroke motorcycle engines, chainsaws, lawn mowers, and similar applications. Moreover, it is compatible with unleaded fuel, further enhancing its versatility and usability across various engine types.


Outboard Oil TCW-3 is the result of an innovative blend of an ashless two-cycle additive package, paraffinic oxidation-stable base oils, and solvents. This exceptional formulation not only meets the stringent TC-W3 Recertified requirements but also exceeds them, including passing the challenging Mercury 15 HP tests twice under the new 15 HP Pass/Fail Criteria, as well as the OMC 70 HP test, improved lubricity performance standard, and the 40 HP procedure.

Outboard manufacturers wanted improved lubricant performance in the area of:

  • Rust protection
  • Ring sticking
  • Ring wear
  • Lubricity
  • Detergency

Furthermore, this product is designed with an additive system that combats the tendency of older oils to form gels or become hazy during storage or at low temperatures, ensuring its reliability and usability over time.

In addition to its exceptional performance, Outboard Oil TCW-3 is engineered with environmental responsibility in mind. It boasts low aquatic toxicity, aligning with evolving environmental standards and regulations. With an LC50 of > 4000 ppm, it is considered non-harmful in terms of aquatic toxicity, further solidifying its commitment to environmental stewardship.


Outboard Oil TCW-3 comes as the top choice for all water-cooled two-stroke outboard engines, including popular brands like Johnson, Evinrude, Mercury, Chrysler, Suzuki, Yamaha, and Tohatsu. Its superior performance and compliance with industry standards make it the optimal lubricant for these engines.

Moreover, the versatility of Outboard Oil TCW-3 extends beyond outboard engines. It is suitable for use in two-stroke motorcycle engines, chainsaws, and lawn mowers, whether they are equipped with an automatic oil injection system or require premixed oil/petrol mixtures. However, it is crucial to adhere closely to the equipment manufacturer’s recommended oil/petrol ratios for optimal performance and engine longevity.

One distinguishing feature of Outboard Oil TCW-3 is its dark purple color, making it easy to visually confirm whether or not oil has been added to the petrol, ensuring proper lubrication and peace of mind during operation.
