Quicksilver 2-Stroke Engine Oil, 1 Gallon — TC-W3 Ashless Dispersion for Outboards & PWCs

Quicksilver Premium 2-Stroke Engine Oil (1 gallon) is a TC-W3 rated, ashless dispersion oil formulated to protect and lubricate outboards, PWCs, snowmobiles, and other 2-stroke small engines.

This heavy-duty conventional 2-stroke oil is engineered to meet Mercury Marine OEM specifications and the NMMA TC-W3 standard, delivering dependable lubrication, deposit control, and corrosion protection across a wide range of marine and powersports applications. It’s an all-weather formula that helps reduce exhaust smoke, resist rust formation in combustion and exhaust passages, and limit spark plug fouling for smoother, more reliable operation.

How does Quicksilver Premium oil protect 2-stroke engines?

The formulation uses ashless dispersant additives to suppress deposits and corrosion while providing a consistent lubricating film where the engine needs it most. Because 2-stroke engines commonly use total-loss lubrication, this oil is balanced to burn cleanly while still guarding rings, bearings and cylinder walls from wear.

• NMMA TC-W3 rating for marine 2-stroke compatibility
• Ashless dispersant reduces combustion chamber and exhaust deposits
• Corrosion inhibitors protect intake and exhaust passages
• Formulated to limit smoke and help prevent spark plug fouling

Can I use this oil with my Mercury or other outboard engines?

Yes. Quicksilver Premium is produced to Mercury Marine OEM specifications and is suitable for Mercury, Mariner and many other outboards, plus PWCs and small carbureted engines. It’s widely recommended for premix use in lower-horsepower and carbureted two-stroke motors.

• Meets Mercury Marine original equipment standards
• Recommended for premix applications in carbureted engines
• Compatible with many brands of outboards and PWC 2-stroke engines
• Good multi-application choice for marine and powersports uses

What operating temperatures and conditions is this oil suited for?

The oil is an all-weather conventional 2-stroke formula designed to perform reliably in a broad range of climates, including colder conditions down to -13°F (-25°C). Its viscosity and additive balance help maintain protection during startup and under mid-range operating loads commonly seen in recreational and work-use small engines.

• All-weather usability to -13°F (-25°C)
• Stable film protects during cold starts and normal running
• Reduces deposit buildup for sustained performance
• Formulated for typical marine and powersports loads

How should I mix and store this 1-gallon container?

Follow engine manufacturer mixing ratios when using premix; many small carbureted engines and outboards have specified oil-to-fuel ratios. Store in a cool, dry place away from direct sunlight and heat sources; keep the container tightly sealed to preserve additive performance and prevent contamination.

• Adhere to your engine’s recommended oil:fuel ratio for premix
• Use clean measuring equipment to avoid dilution errors
• Store sealed in a cool, dry location away from flames
• Rotate stock: use older containers first for best performance

Who is this for? Quicksilver Premium 2-Stroke Engine Oil is aimed at boaters, PWC riders, snowmobile owners, small-engine technicians and powersports enthusiasts who want a factory-aligned oil engineered to meet marine OEM standards. If you run two-stroke outboards, personal watercraft, or other small total-loss lubrication engines and value deposit control, corrosion prevention and predictable burn characteristics, this 1-gallon solution supplies the protection and convenience expected from a brand with deep marine expertise.
