Sint 40 R/T is a full synthetic extreme pressure, low viscosity, gear lubricant enhanced with SuperLube Technology (SLT) is especially manufacturered for high performance, sporting and competition cars. This unique formulation is carbon neuteral, energy efficient and designed to provide maximum lubraction film strength under the mst varied and harsh conditions. Sint 75/90 R/T provides exceptional anti wear protection during initial start up while providing maximum viscosity at high temperatures for greater resistance to lubrication breakdown. Superior road & Track synthetic formulation now enhanced with SLT provides maximum protection for high technology, high output, turbo and non turbo, petrol, LP gas and diesel engines requiring a 0w40 performance motor oil.
