Product Details Keep your 2-stroke outboard running clean and strong with Star Brite Super Premium Synthetic TC-W3 2-Stroke Oil, a full-synthetic marine engine oil that helps anglers protect high-performance motors through long runs, repeated starts, and hard fishing days chasing walleye, bass, salmon, tuna, and other gamefish. This 1 gallon oil works with FICHT, E-TEC, Optimax, and HPDI outboards along with personal watercraft, pre-mix systems, and direct-injection designs, giving boat owners broad compatibility across modern 2-cycle applications. Its PIB viscosity modifier helps reduce smoking and support smoother engine performance, while the high-detergent formula cleans deposits from the fuel delivery system to keep the engine efficient. This cleaner-burning TC-W3 oil also helps minimize piston ring sticking, guards against pre-ignition problems, reduces emissions, and delivers long-lasting protection that helps extend engine life through demanding marine use.
