Quicksilver (Oils & Accessories)

Quicksilver Performance DFI is a high-performance, synthetic-blend 2-stroke oil specifically formulated for outboard engines with Direct Fuel Injection (DFI), including Mercury OptiMax, Yamaha HPDI, Evinrude E-TEC, and other modern engines. With a unique blend of enhanced base oils and synthetic additives, this oil minimizes carbon deposits and keeps engines clean and responsive, while providing superior lubrication at high RPM and temperatures. The result is extended engine life, maximum power output, and reduced smoke.

• Designed for DFI engines – ideal for Mercury OptiMax, Yamaha HPDI, Evinrude E-TEC, and similar direct-injected 2-stroke systems
• Synthetic carbon-fighting additives – significantly reduce carbon buildup, preserving compression and engine efficiency
• High-load protection – guards cylinders against scuffing and wear under extreme RPM and heat
• Lower smoke and odor – clean-burning formulation with low smoke output for a better boating experience
• NMMA TC-W3 approved – meets TC-W3 standards while excelling under the demands of DFI applications
