AMSOIL 100% SYNTHETIC 2-STROKE INJECTOR OIL

AMSOIL 100% Synthetic 2-Stroke Injector Oil delivers clean-burning wear protection for snowmobiles, outboard motors, and personal watercraft, all from a single formula that performs in conditions ranging from sub-zero trail rides to wide-open-throttle summer runs on the water.

Two-stroke engines live hard. They run at high RPM, rely on the fuel-oil mixture for all their lubrication, and operate in environments that promote rust and corrosion. Snowmobile engines face brutal cold starts where conventional oil can be too thick to flow, while outboard motors sit in constant contact with moisture. A two-stroke oil that can handle both extremes without compromise is not a luxury. It is a requirement.

ONE OIL FOR SNOWMOBILES, OUTBOARDS, AND PWC
Most riders and boaters own more than one piece of two-stroke equipment, and juggling multiple oil formulations is unnecessary. AMSOIL Synthetic 2-Stroke Injector Oil is engineered to cover the full range of two-stroke recreational applications. It works as injection oil or as a 50:1 pre-mix at 2.6 oz. per U.S. gallon of gas. Compatible with engines from Ski-Doo, Polaris, Arctic Cat, Yamaha, Mercury, Evinrude, Johnson, Kawasaki, Suzuki, Sea-Doo, Mariner, and Force, it replaces the patchwork of brand-specific oils cluttering your garage shelf.

PROTECTS AGAINST PISTON SCUFFING AND BEARING WEAR
Two-stroke engines have no dedicated oil sump. Every bit of lubrication has to arrive with the fuel charge, which means film strength is critical. AMSOIL Synthetic 2-Stroke Injector Oil is formulated with high-lubricity synthetic base oils that maintain a reliable protective film between the piston, cylinder wall, and bearings. This directly reduces scuffing and wear in high-RPM, high-heat operation, the kind of running that a Ski-Doo 850 E-TEC or a Mercury 200hp two-stroke outboard sees on a regular basis.

COLD-FLOW PERFORMANCE DOWN TO -60°F
A pour point of -60°F (-51°C) is not a number pulled from a lab curiosity. It means this oil flows rapidly through injection systems during frigid snowmobile startups when other oils can lag. The formulation also passes SAE J1536 Fluidity/Miscibility Grade 4 Arctic Climate testing, confirming pumpability at -40°C with viscosity held below 17,000 cP. For snowmobilers in Minnesota, Wisconsin, Ontario, or anywhere temperatures plunge well below zero, that cold-start flow translates directly to less dry-start wear on pistons and cylinders.

CLEAN-BURNING FORMULA FIGHTS DEPOSITS
Deposits are the silent performance killer in two-stroke engines. Carbon buildup on piston rings causes ring sticking and ring jacking, robbing compression and power. Exhaust power valve fouling restricts flow and dulls throttle response. AMSOIL Synthetic 2-Stroke Injector Oil uses synthetic base oils that burn more completely than conventional oils, leaving less residue behind. High-temperature detergent and dispersant additives actively resist deposit formation, keeping rings free, exhaust valves clean, and compression where it should be. Less smoke, more power.

RUST AND CORROSION PROTECTION FOR WET ENVIRONMENTS
Outboard motors and personal watercraft live in the worst possible conditions for bare metal surfaces. Saltwater, brackish water, and even freshwater humidity invite corrosion during storage and between uses. AMSOIL Synthetic 2-Stroke Injector Oil contains potent rust and corrosion inhibitors that coat and protect internal metal surfaces, reducing the damage that occurs during seasonal downtime or extended periods between starts.

SPECIFICATIONS AND COMPATIBILITY
AMSOIL Synthetic 2-Stroke Injector Oil meets API TC and TC-W3 specifications. It is compatible with most conventional and synthetic two-stroke oils, though mixing is not recommended for best results. For Evinrude engines running the factory-lean oil setting, AMSOIL recommends HP Marine Synthetic 2-Stroke Oil instead. This product is Warranty Secure, meaning it keeps factory warranties intact when used as directed.

MIX RATIO
Use as injection oil per the engine manufacturer's system, or pre-mix at 50:1 (2.6 oz. per U.S. gallon of gasoline).
