Purpose and Specifications

Millers XF Premium C3 5W40 is a fully synthetic engine oil designed for petrol, diesel, and hybrid engines in modern vehicles. It flows easily at cold starts down to -30°C for instant protection and stays thick up to 150°C to shield pistons, bearings, and timing chains during hard driving.

Key specs include 1L volume, mid-SAPS formula that protects diesel particulate filters (DPF) and catalytic converters, and approvals from BMW Longlife-04, Mercedes 229.51/52, VW 511.00, Porsche C40, GM dexos2, and Renault RN0700/0710. Dynamic Fluid Technology reduces wear, cuts fuel use by up to 3%, and keeps engines cleaner for longer.
