Two-Stroke Oils For Snowmobiles
AMSOIL Interceptor Synthetic 2-Stroke Oil
This legendary snowmobile oil is the gold standard for modern, high-performance two-stroke engines. It is formulated to replace the synthetic 2-cycle oils offered by Ski-Doo, Polaris and Arctic Cat. Interceptor delivers the utmost in wear control and optimizes performance under the hardest riding imaginable. It is also packed with ingredients that keep power valves and engine internals cleaner for longer. Interceptor isn’t just an injector oil. It is likely the most cost-effective performance upgrade for your 2-stroke sled.
AMSOIL Synthetic 2-Stroke Injector Oil
Synthetic Injector Oil is ideal for older snowmobiles or those without variable exhaust power valves. Also ideal for older snowmobiles equipped with power valves. This product delivers synthetic performance and wear control at a value-price. A significant upgrade over mineral and semi-synthetic 2-stroke oils.
AMSOIL Dominator Synthetic 2-Stroke Racing Oil
For racing-only snowmobile engines that are frequently torn down. Designed for engines that are extremely modified and tuned for competition. For snowmobiles that are used for recreational-use, Interceptor (see above) is a far better option. This is due to Interceptor’s ability to keep power valves clean. Even mountain snowmobiles that have turbos added should use Interceptor and not the racing-only Dominator.
Four-Stroke Oils For Snowmobiles
AMSOIL Formula 4-Stroke Powersport Synthetic 0W-40 Motor Oil
A 100%-synthetic engine oil for any snowmobile requiring a 0W-40. For example, most Yamaha, Arctic Cat and Ski-doo 4-strokes require a 0W-40 motor oil. Pours down to -60°F for exceptional oil flow at start-up. Resists thinning at high operating temperatures and under extreme loads. This is an ultra-powerful formula that will protect your engine from anything winter can throw at it. Ideal for turbo or naturally-aspirated engines.
AMSOIL ATV/UTV Synthetic 5W-50 Synthetic Motor Oil
Many Polaris 4-stroke snowmobiles require the use of a 5W-50 or 0W-50. AMSOIL ATV/UTV Synthetic ATV/UTV 5W-50 Engine Oil fits the bill. It is designed to withstand severe operating conditions. This product has a cold-pour-point of -54°F for fast engine protection at start-up. It also boasts a powerful anti-rust and corrosion package. The ideal replacement for Polaris PS-4 Full Synthetic 5W-50 All-Season Engine Oil.
AMSOIL ATV/UTV Synthetic 0W-50 Synthetic Motor Oil
A fine substitute for Polaris PS-4 Extreme Full-Synthetic 0W-50 Engine Oil. Delivers world-class protection for Polaris 4-stroke engines, including turbo-charged models. Pours down to -54°F. Also formulated to protect engine internals against corrosion during the off-season.
Chaincase Oil
AMSOIL Synthetic Chaincase & Gear Oil
An upgrade for any snowmobile. Powerful extreme-pressure ingredients protect chaincase components against extreme shock loads. The synthetic formula reduces friction for optimum power delivery. Also designed to combat internal rust and corrosion.
Chassis Grease For Snowmobiles
AMSOIL Synthetic Water Resistant Grease
The best grease choice for snowmobile steering and suspension pivots. Resists snow, ice water and mud to stay put over long distances. The synthetic formula reduces friction in cold weather, allowing greased components operate smoothly.
Gasoline Additives For Two-Stroke And Four-Stroke Snowmobile Engines
AMSOIL Quickshot Gasoline Additive
Quickshot is one of those “musts” for snowmobiles. It cleans fuel systems and combustion chambers, protects against moisture/ethanol problems, mitigates contaminated fuel and provides “in-season” gasoline stabilization. Quickshot keeps your fuel system like new and prevents several gasoline-related issues that can potentially ruin a day.
When putting your snowmobile into summer storage, it’s time to employ a long-term gasoline preserver. AMSOIL Gasoline Stabilizer keeps gas fresh for up to one year. Prevents fouled injectors and dirty carbs. Allows for easy start-up and perfect performance after long-term storage.
