Signature Series brings not only industry-leading performance, but top value as well; its extended-drain performance delivers guaranteed protection for up to 25,000 miles, 700 hours of operation or one year, whichever comes first. AMSOIL Signature Series Synthetic Motor Oil offers a rare combination of performance and value.

CSC currently stocks: SAE 5W-20, and SAE 5W-30.

Compressor Oils

AMSOIL PC Series Synthetic Compressor Oil is a long-life, premium compressor lubricant based on novel, proprietary technology. It incorporates the highest quality, thermally stable PAO synthetics fortified with premium non-detergent additives for maximum protection at high temperatures. It lasts up to 8,000 hours, effectively reducing maintenance and waste oil disposal costs.

CSC currently stocks: ISO 100/SAE 30/40, and ISO 46/SAE 20.

Dominator 2-Stroke Racing Oil

Racers can’t win what they don’t finish. That’s why AMSOIL formulators built DOMINATOR® 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. These engines operate on the edge, yet engine reliability is critical. DOMINATOR does an outstanding job protecting high-performance engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed to the limit.

SAE 15W-40 Heavy-Duty Diesel and Marine Motor Oil

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.

Motorcycle oilsamsoil-motorcycle-oil

AMSOIL Synthetic Motorcycle Oils have been reformulated with new high performance additive technology that provides even greater multi-functional benefits for the special requirements of motorcycle applications. These independent and exclusive new AMSOIL formulations provide second-to-none viscosity protection for hot-running American and foreign motorcycle engines, transmissions and primary chaincases.

CSC currently stocks: SAE 20W-50, and SAE 10W-40.

HP Marine Synthetic 2-Stroke Oil

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 an injection oil or at 50:1 pre-mix.

Formula 4-Stroke 10W-30/SAE 30 Small Engine Oil

Commercial-grade formulation for hot temperature, severe service operation of small engines where routine maintenance is often difficult or infrequent. Use wherever SAE 10W-30 or SAE 30 oil is specified in gasoline or diesel engines, transmissions, hydraulics and chaincases.

Severe Gear 75W-110 Synthetic Extreme Pressure Lubricant

For the severe operating conditions of today’s hard working vehicles. Engineered for high-demand applications, including trailer towing, heavy hauling, 4X4 off-road driving, commercial use and racing.

In 1972, AMSOIL set all-new standards for motor oil quality when it introduced the worlds first synthetic motor oil to meet American Petroleum Institute (API) service requirements. Today, AMSOIL remains steadfast in its commitment to quality and precision lubricant engineering.

The company’s state-of-the-art mechanical testing laboratory allows it to stay on the cutting edge of lubricant technology. Equipped with three 480-sq. ft. dynamometer cells capable of housing a minimum of two dynamometers each, the facility allows AMSOIL to test motor oil performance on-site, allowing quick turn-around times, the ability to modify conditions to measure different oil properties and unique testing not available elsewhere.
