In a Hypoid type axle the teeth on the crown wheel and pinion simultaneously rotate and slide against one another, putting high pressure on the faces of the teeth. This action requires the use of extreme pressure (EP) additives to the oil to prevent wear. This multigrade oil was especially developed for self-locking or limited-slip, ZF or Salisbury type differentials. These can be found on sports cars such as Jaguar, Aston Martin or Maserati.
