Purpose and Specifications

Shell Helix HX8 ECT C3 5W-30 1L is a fully synthetic engine oil designed for modern gasoline, diesel, and gas engines, including those with diesel particulate filters (DPF). It delivers relentless protection by actively cleansing deposits, reducing wear, and keeping emissions systems clean for smoother performance.

This premium oil flows easily at cold starts down to -30°C for quick engine warm-up, while staying thick and protective up to 150°C in hot conditions. It cuts engine friction for better fuel economy - up to 1.7% savings - and lowers oil top-up needs with low evaporation. Approved for ACEA C3, BMW Longlife-04, Mercedes-Benz 229.51 and 229.31 specs, it's perfect for vehicles needing low-SAPS oil to avoid clogging exhaust systems.

• Extends engine life in tough driving like city traffic or highways

• Reduces emissions and fuel use without sacrificing strength
• Suitable for biodiesel and ethanol blends
