AMSOIL Series 2000 Synthetic 2-Cycle Racing Oil

Product Code: TCR


AMSOIL Series 2000 Synthetic 2-Cycle Racing Oil (TCR) is a formulation of carefully selected pure synthetic esters and premium additives, providing excellent performance in both air cooled and water cooled two-cycle motors. AMSOIL TCR is fortified with corrosion inhibitors to prevent rust from condensation at shut down and during off-season storage. The AMSOIL racing formulation is based on extensive research conducted both in-house and in independent laboratories. AMSOIL TCR provides superior lubrication, protection and performance for two-cycle motors in the most demanding applications.

Reduces Friction and Heat

In extreme conditions where operating temperatures are high, two-cycle motors lose power and torque. The aluminum pistons expand from heat and cause an increase in friction. AMSOIL Series 2000 2-Cycle Racing Oil is a special blend of synthetic esters and additives that reduce friction, prevent metal-to-metal contact and provide maximum protection against piston scuffing.

The ASTM D-4863 two-cycle motor lubricity test measures torque output at 350 C (662 F). Higher torque output means better lubricity and more power. This test is a requirement for NMMA TC-W3 and API TC specifications. As the graph shows, AMSOIL Series 2000 2-Cycle Racing Oil minimizes power loss due to friction.

Keeps Engines Clean

AMSOIL Series 2000 2-Cycle Racing Oil contains ash-less detergent additives that have been tested and proven to provide superior cleanliness in both air and water-cooled motors. AMSOIL Series 2000 2-Cycle additives inhibit the formation of deposits in the ring grooves, in the combustion chamber and on the exhaust power valves. With AMSOIL Series 2000 2-Cycle Racing Oil rings do not stick and spark plugs do not foul from carbon deposits, and exhaust power valve maintenance is minimized.
