This premium diesel engine oil is engineered for modern passenger cars and light commercials, including DPF-equipped models, to deliver strong performance, dependable protection and excellent fuel economy. The 7L pack makes servicing easy, and APEX+ Advanced Fluid Dynamics reduces friction so your engine revs freely, responds crisply and runs cooler in everyday commuting, heavy loads or long highway runs. Cold mornings are no problem-its fast-flowing, low-viscosity formula reaches critical components quickly to limit start-up wear. Once warm, superior oxidation control and thermal stability keep the oil in grade, resisting thickening and breakdown during long drain intervals recommended by your manufacturer. Detergent additives help maintain engine cleanliness, so turbochargers, EGR systems and aftertreatment stay happier for longer. It’s also GM dexos2 licensed, making it a trusted choice for many late-model European and General Motors diesels, while remaining suitable for petrol engines where a 5W-40 is specified. If you want smoother starts, quieter running and maximum protection from one bottle, choose Nulon APEX+ 5W-40.
