AMSOIL Marine Oil

AMSOIL Marine Oil is a premium synthetic formulation designed to withstand the heat and stress of high-rpm operation and deliver excellent wear protection. AMSOIL outboard motor oil protects against rust and corrosion during periods of inactivity and long-term storage to keep your engine protected, even when it’s not running. AMSOIL is perfect for hardcore anglers and boating enthusiasts who demand the best protection for their marine engines.

AMSOIL Synthetic Marine Engine Oil is specially engineered for marine applications. Durable formulation protects in severe conditions, from all-day trolling to high-rpm operation. Heavily fortified with advanced additives designed to prevent deposits, rust, and corrosion. Use in gasoline-fueled four-stroke inboards, outboards, inboard/outboards, and personal watercraft, including those made by Honda, Mercury, Yamaha, Johnson/Evinrude, Bombardier/BRP, Suzuki, Nissan, Tohatsu, OMC, Volvo-Penta, Mercruiser, Chevrolet, and Ford.

HP Marine Synthetic 2-Stroke Oil is excellent for Evinrude® E-TEC™ factory-lean setting (replaces Evinrude XD100™ 2-Cycle Oil). Helps prevent deposits, protects against wear, has low smoke, protects against rust, and has low aquatic toxicity. Superior performance as injection oil or at 50:1 pre-mix.

Synthetic 2-Stroke Injector Oil is perfect for use in all two-stroke outboards where TC-W3 or API-TC oils are specified, including Evinrude/Johnson, Mariner, and Force outboard motors. It offers the convenience of one formula for the tough conditions of all two-stroke outboard motors. AMSOIL's synthetic base oils burn cleanly to help prevent power-robbing deposits. It is fortified with high-temperature detergent and dispersant additives that naturally resist harmful deposits.
This helps prevent ring sticking, ring jacking, and exhaust power valve sticking for maximum compression, power, and performance.

Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil is specifically designed for outboard motors, Outboard 100:1 Pre-Mix Synthetic 2-Stroke Oil contains a heavy dose of low-temperature dispersant additives that excel at reducing varnish, carbon, and deposit formation in water-cooled motors. Its low-smoke, low-odor, low-toxicity properties produce fewer emissions at 100:1 mix ratios than oils mixed at 50:1, benefitting operators and the environment. Outboard Synthetic 2-Stroke Oil is formulated to prevent "oil loading" and plug fouling for rapid throttle response, making it ideal for trolling motors.

AMSOIL Synthetic Heavy-Duty Diesel & Marine Motor Oil is a premium diesel oil that provides excellent performance in all types of diesel engines where highly effective control of wear and deposits is vital. Engineered with heavy-duty dispersant/detergent additives, its Total Base Number (TBN) of 12 neutralizes acids and controls soot thickening from exhaust gas recirculation (EGR) and blow-by to protect against corrosion, cylinder bore polishing (wear), varnish and sludge deposits. AMSOIL 15W-40 Diesel Oil resists heat and breakdown better than conventional petroleum oils for long-lasting performance and protection.

AMSOIL Synthetic Marine Gear Lube 75W-90 delivers exceptional wear protection, even when contaminated with up to 15 percent water. Extreme-pressure formulation controls damage from shock-loading caused by propeller cavitation. Excellent for fast-accelerating, high-horsepower boats. Protects against rust and corrosion. Keeps seals soft to minimize water leakage. Compatible with other synthetic and conventional oils. Use in fresh- and saltwater applications that require 75W-90 or 80W-90 gear lube and any of the specifications listed below, including lower units made by Mercury/ Mariner, Johnson/Evinrude, Bombardier, Honda, Yamaha, Suzuki, Force/US Marine, Nissan, Tohatsu, and Harbormaster; sterndrives made by Mercruiser-Bravo, OMC/Bombardier, Volvo-Penta, Yanmar, Konrad, and Marine Drive Systems; V-drives made by Casale & Menkins; bow thrusters made by Harbormaster Marine; and transmissions made by ZF Marine Transmission.
