Xlf outboard two-cycle oil mixes easily with gasoline, and is dyed Blue to allow for easy detection. Follow engine manufacturer's recommended fueloil ratio for premix systems. Maximum additive treatment, including increased detergency over the TC-W3 formulation. Nmma TC-W3 certified. Protect against piston-scuffing. Keep performance-robbing carbon deposits from forming in the combustion chamber, piston tops and under crowns and piston-combustion rings.

Designed for NMMA FC-W 4-Stroke outboard engines use in gasoline-fueled four-stroke inboards, outboards, inboardoutboards, supercharged watercraft engines and personal watercraft. True full synthetic twice the life of conventional and synthetic blends oil and twice the protection. Unmatched corrosion protection, even in continuous salt water use, including up to two years of storage excellent stability and viscosity control for long term high temp operation. Friction modified for exceptional wear protection, less heat, better fuel economy, and significantly reduced wear. High film strength and durability under high torque and power output conditions.
