Nulon Apex , with Advanced Fluid Dynamics, dramatically improves engine oil flow efficiency to reduce power-robbing friction and maximise engine performance when you need it. Responding to driving inputs, Nulon Apex flows faster at low temperatures and resists extreme pressure, heat and wear of contacting metal surfaces to promote ultimate performance, fuel efficiency and protection in both everyday stop/start and the most demanding driving conditions.Nulon Apex 5W-30 Fuel Efficient engine oil provides the maximum protection and performance from cold-start to high operating temperatures. The fuel conserving, low viscosity formula ensures optimum engine performance for all technically advanced and performance petrol, passenger and light commercial diesel engines.
