Our full synthetic formula withstands extreme temperatures and high loads, delivering cleaner engine performance, reduced sludge, corrosion resistance, and minimized oil burn-off. Better Wear Protection & Reduced Thermal BreakdownWith over 80% better protection than the latest API requirements, it reduces friction during high torque and acceleration. The advanced formulation helps keep engines running cleaner and stronger by resisting high-heat degradation and deposit formation. Ideal for Severe Marine ConditionsDesigned for gasoline-fueled marine engines operating under extreme conditions, it also offers reliable protection for turbochargers and emission control systems. Why Choose Full Synthetic Over Synthetic Blend?Unlike synthetic blends that only contain a small percentage of synthetic base oil, Malibu Full Synthetic 5W-30 provides full-performance benefits at a comparable cost—without compromise.
