Super-M is a high performance racing 2 stroke lubricant incorporating the latest technology. Super-M is a blend of clean burning petroleum base oil, synthetic polyolester, polybutene, anti-scuff/anti-wear compounds and a new additive that keeps rings, power valves and the exhaust tract 'carbon free'. Another newly developed additive 2000 Centistoke Ester provides additional anti-scuff protection as well as enhanced rust and corrosion protection. This environmentally friendly 'smokeless' formula is in a class by itself.
