Quicksilver 2-Stroke Premium Plus Synthetic Blend Marine

Quicksilver 2-Stroke Premium Plus Synthetic Blend is a TC-W3-rated 32oz marine engine oil engineered to protect and lubricate 2-stroke outboards, PWC and small engines under heavy and high-speed use.

Designed by Quicksilver—the longstanding Mercury Marine OEM partner—this Premium Plus synthetic blend oil combines ashless dispersant chemistry with formulation tuned for severe marine and powersports conditions. It reduces exhaust smoke, fights carbon and rust deposits, and is suitable for oil injection systems or premix. The 32oz bottle offers a convenient quantity for routine maintenance or field top-ups.

How does Quicksilver Premium Plus reduce smoke and carbon buildup?

The formula contains ashless dispersants and detergents that suspend combustion by-products and prevent them from agglomerating into deposits. Cleaner combustion means less visible exhaust smoke and lower risk of spark plug fouling or ring sticking over time.

• Ashless dispersant chemistry helps keep deposits suspended and burn out cleanly
• Detergent components guard against combustion chamber and exhaust carbon
• Optimized for TC-W3 standards that target smoke and deposit control

Can I use this oil in oil-injection systems and premix applications?

Yes — the Premium Plus synthetic blend is formulated for both oil-injection systems and manual premix. It mixes reliably with fuel and delivers the protective film thickness necessary for high-revving 2-stroke crankcases and ports.

• Compatible with oil-injection metering systems used on modern outboards and PWCs
• Stable miscibility for accurate premix ratios when manual blending is required
• Sized at 32oz for convenient dosing and storage on the boat or garage

What levels of corrosion protection and durability does it provide?

Quicksilver engineers this oil to resist rust and corrosion in the combustion chamber, intake and exhaust passages — areas especially vulnerable to moisture and salt exposure. Its protective additives help maintain engine surfaces and prolong component life under marine operating conditions.

• Corrosion inhibitors protect metal surfaces from moisture and salt exposure
• Designed for high-horsepower, continuous wide-open-throttle (WOT) operation
• Meets Mercury Marine OEM specifications for consistent performance

How does it support high-performance starts and heavy loads?

The oil’s formulation responds quickly to instant power demands such as hole shots and sustained high-speed runs. It maintains a protective lubricating film across bearings, cylinders and rings even during rapid rev increases, reducing wear in aggressive operating conditions.

• High film strength for load-bearing protection during rapid acceleration
• Stable thermal behavior for sustained high-rpm and long-distance runs
• Developed and tested with Mercury Marine standards for performance reliability

Who is this for? Boaters, PWC riders and powersports enthusiasts who run 2-stroke outboards, personal watercraft, motorcycles, snowmobiles or other small engines and demand a TC-W3-rated, ashless dispersant oil. It’s particularly suited to those operating in corrosive or high-performance environments who need an oil that reduces smoke, prevents deposits and meets OEM protection standards.

Features include superior lubrication for 2-stroke engines, corrosion prevention in combustion and exhaust passages, dual compatibility with injection systems and premix, and formulation optimized for high-horsepower marine use. Choose Quicksilver Premium Plus for an OEM-aligned oil designed to keep your 2-stroke running cleaner and more reliably.
