Description:

TC-W3 Direct Injection 2-Cycle Marine Oil – 1 Gallon / 3.785L (18-9530-3)

High-performance direct-injection formula for modern 2-stroke outboards.

This TC-W3 Direct Injection Marine Oil is engineered for today’s high-horsepower 2-cycle outboards that require clean, reliable, maximum-performance lubrication. Its advanced formulation reduces ring sticking, deposit buildup, and exhaust port blockage—resulting in easier starting, smoother running, and extended engine life even under heavy load and high-temperature operation.
Designed for both direct-injection and traditional oil-injection or pre-mix systems, this oil delivers exceptional performance with a wide range of fuel qualities. It also provides significantly reduced aquatic toxicity compared to many competing outboard oils on the market. Exceeding JASO, ISO, API, and NMMA specifications for advanced 2-cycle lubricants, it is fully compatible with and will not void any major engine manufacturer warranty.
