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-40 Performance engine oil features high thermal stability to suit ultra-high-performance passenger cars and light commercial petrol and diesel engines. The technically advanced fast flowing formulation is specifically designed to provide increased protection during long oil drain intervals.
