Purpose and Specifications

Shell Helix HX8 ECT C3 5W40 5L is a fully synthetic engine oil designed for modern petrol and diesel engines, especially those with diesel particulate filters (DPF). It uses advanced low-SAPs technology to keep filters clean and prevent ash build-up that blocks exhausts and cuts performance. This premium oil flows 30% faster for quick starts and warm-ups down to -30°C, while staying thick up to 150°C for relentless protection.

• 40% better wear protection than industry standards - shields engine parts in tough conditions like stop-start traffic or heavy loads
• 60% superior corrosion protection - guards against rust even after long drives
• Excellent viscosity control - maintains thickness through heat and shear for consistent power
• Meets top specs: ACEA C3, API SN, BMW LL-04, MB 229.31/229.51, Renault RN0700/0710, Fiat 9.55535-S2

5-liter pack suits most cars for a full oil change. Shelf life is 5 years unopened when stored cool and dry.
