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 Long Life engine oil is a General Motors dexos2 approved formula designed to provide ultimate performance and protection for all technically advanced passenger car and light commercial petrol and diesel engines, including vehicles fitted with Dielse Particulate Filters (DPFs).
