Purpose and Specifications

Shell Helix Ultra ECT C3 5W-30 is a premium fully synthetic engine oil in a convenient 20L size, designed for modern gasoline and diesel engines with emission systems like diesel particulate filters (DPF). Its 5W-30 viscosity flows easily at cold starts down to -30°C for quicker warm-up, while staying thick up to 150°C to protect against wear in hot conditions. This low-friction formula delivers up to 1.7% better fuel economy, keeps engines factory clean with unbeatable sludge protection, and uses low-SAPS technology to prevent ash buildup in exhaust systems for lasting performance.

Approved for ACEA C3, MB 229.51, MB 229.31, API SN, BMW Longlife-04, GM dexos2, and Chrysler MS-11106, it's perfect for high-performance vehicles under severe driving like city traffic or long hauls.

When to Use / Replace?

Use this oil in vehicles with DPF or catalysts for clean emissions and extended engine life. Ideal for extreme temps from -30°C winters to 150°C summers, or tough conditions like towing. Replace every 15,000-30,000 km or 12 months, whichever comes first, to maintain peak protection—check your owner's manual. Shelf life is 5 years unopened in cool, dry storage.

• Quick cold starts: Flows fast below freezing for reliable winter driving.
• Hot weather durability: Resists breakdown at high temps for less top-up.
• Fuel savings: Low friction means more km per tank.
• Engine longevity: Cleans deposits to avoid power loss.
