A full synthetic racing gear oil that carries a suspension of microscopic solid particles as its extreme-pressure agent, for low drag with high protection. It gives film thickness greater than an SAE 75W250 with low fluid friction, for heavily loaded racing differentials and transmissions with splash (wet-sump) lubrication.
