Formula 4-Stroke® Marine Oil
Synthetic Motor Oil 10W-30 & 10W-40
AMSOIL Formula 4-Stroke® Marine Synthetic Motor Oil is a premiumquality synthetic formulation engineered for the harsh operating conditions of marine environments. It withstands the intense mechanical action of continuous, high-rpm operation to deliver superior viscosity protection.
Formula 4-Stroke Marine Synthetic Motor Oil is specially fortified
with a heavy treatment of advanced additives that protect motors against wear, rust and deposits. It excels in high-horsepower applications and all-day trolling conditions.
4-Stroke Outboard Motor Warranty Certified
Formula 4-Stroke Marine Synthetic Motor Oil is certified by the National Marine Manufacturers Association (NMMA) for use in four-stroke outboard motors. This high-quality oil demonstrates outstanding performance, exceeding the NMMA “FC-W” (Four Cycle - Water) specification requirements. Formula 4-Stroke Marine Synthetic Motor Oil fulfills the warranty requirements of four-stroke outboard motor manufacturers.
• NMMA Registration #FB-30010B 10W-40
• NMMA Registration #FB-30011B 10W-30
Superior Protection Against Engine Wear
Marine engines operate under high loads and rpm for extended periods of time, causing traditional automotive oils to break down and lose viscosity. To ensure good protection, the NMMA set minimum shear stability requirements for FC-W. AMSOIL
Formula 4-Stroke Marine Synthetic Motor Oil greatly exceeds the FC-W shear stability requirements, outperforming competitive oils to deliver a superior lubricating film.
Formula 4-Stroke Synthetic Oil contains robust anti-wear additives that further reduce wear in metal-to-metal contact regions, while high zinc and phosphorus levels protect flat-tappet camshaft marine engines against wear.
Excellent Anti-Rust Performance
Marine engines are prone to rust, leading to uncontrolled wear and premature engine failure. However, good rust protection is not natural to engine oil; it comes only by design. Formula 4-Stroke Marine Synthetic Motor Oil is fortified with a special anti-rust agent, even more than required to pass stringent NMMA FC-W anti-rust testing
