Purpose and Specifications

Shell Helix Ultra ECT C3 5W-30 1L is a fully synthetic engine oil designed for modern gasoline and diesel engines, especially those with diesel particulate filters (DPF) and exhaust catalysts. Its low-SAPS formula (low in sulphated ash, phosphorus, and sulfur) keeps emission systems clean by preventing ash build-up that blocks exhausts and cuts performance. The 5W-30 viscosity flows easily at cold starts down to -30°C for quicker warm-up, while staying thick up to 150°C under high heat and stress. This cuts internal friction for up to 1.7% better fuel economy, reduces wear on pistons, cylinders, and bearings, and provides unsurpassed sludge protection to keep your engine cleaner than factory fresh.

• Key Benefits: Superior cleaning removes power-robbing deposits, low evaporation means less topping up, and special antioxidants fight oxidation for full oil life.
• Works in extreme hot/cold climates and severe driving like towing or city stop-go.
• 1L bottle perfect for top-ups or small engines.

When to Use / Replace?

Use this oil in vehicles requiring ACEA C3 specs for emission-controlled engines. Replace every 10,000-15,000 km or 12 months under normal driving; cut to 7,500 km or 6 months for severe conditions like dusty roads or high loads. Shelf life is 4-5 years unopened in cool, dry storage.
