A full synthetic engine oil for competition engines typically in highly stressed endurance conditions. API SL/CF.
Millers Oils full synthetic Motorsport formulations combine 3 synthetic esters with high performance additives (including the optimum amount of ZDDP Zinc antiwear additive) and friction modifiers to provide maximum power output with minimum wear. The high ester content reduces the amount of polymer in the formulation and increases the oil’s resistance to shear and loss of viscosity. Millers Oils formulations are recommended by many engine builders for highly stressed applications in racing, rallying, track day and fast road use. If a 5W40 is specified, upgrade to 10W40. If 10W40 is specified, upgrade to 10W60. This is very important on turbocharged engines to protect the turbo.
