Mercury OptiMax/DFI 2-Cycle Outboard Oil 2.5 gal | Premium Synthetic Blend

Overview

Designed for high-performance OptiMax and DFI outboards, this synthetic blend oil is crafted to meet the hotter, leaner demands of modern two-stroke engines. It emphasizes lubricity, helps minimize carbon deposits, and reduces smoke, while delivering robust protection for the heart of the motor. Note that it is not intended for every TCW3 specification, so always verify your engine’s requirements before use.

Mercury’s exclusive formula blends a carefully modified base stock with a synthetic additive package, resulting in smooth lubrication that can help maintain top-end performance. The oil is formulated to work with standard 2-cycle oils, giving you flexibility without sacrificing protection.
