Detailed advantages listed below: 

  1. High film strength dramatically reduces engine wear and reduces impact of heat generated as a result of moving parts, thereby extending the life of your engine. 
  2. Horsepower and torque are maximized while optimizing fuel economy as a result of sealing the piston ring and cylinder wall. 
  3. Improved synthetic solvency reduces the deposits from the engine, keeping it clean. 
  4. Wear protection for valve train components which includes performance roller lifter and high lift flat tappet camshafts and lifters. 
  5. Enhanced corrosion protection

One of the best things about this motor oil is its versatility. You can use it both on diesel and gasoline engines.  Another of its benefits is its high film power which is 2 to 3 times more effective than other full synthetic oil in the market.
