Nulon Apex+ Full Synthetic Fuel Efficient 5W-30 Engine Oil 5L 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.
