Shell Helix Ultra Professional AP-L 0W-30
Shell Helix Ultra Professional AP-L 0W-30 is a premium fully synthetic motor oil developed to meet the demanding lubrication requirements of modern high-performance gasoline and diesel engines. The oil is formulated using advanced synthetic base oils and carefully selected additive technology to provide excellent engine protection, improved fuel efficiency and consistent lubrication performance across a wide range of operating conditions. It has been specifically engineered to meet the technical requirements of modern Peugeot and Citroën engines that require advanced low-viscosity lubricants.
One of the key advantages of Shell Helix Ultra Professional AP-L 0W-30 is its ability to support improved fuel efficiency. The oil has been tested using the ACEA M111FE fuel economy procedure and demonstrates a minimum fuel efficiency improvement of approximately 2.5 percent compared with industry reference oils. Reduced internal engine friction allows moving components to operate more efficiently, helping engines achieve improved fuel economy while maintaining reliable lubrication performance. These benefits are particularly important for modern engines designed to meet strict fuel economy and emissions targets.
The oil also provides excellent wear protection and engine durability. During normal engine operation, components such as pistons, camshafts and bearings operate under high loads and temperatures. Shell Helix Ultra Professional AP-L 0W-30 forms a durable lubricating film that helps reduce metal-to-metal contact between moving engine components. This protective film helps minimise wear and contributes to extended engine life while maintaining reliable lubrication performance throughout the oil drain interval.
Another important benefit of the oil is its ability to maintain engine cleanliness. Combustion by-products and degraded oil can accumulate inside the engine over time and lead to sludge or deposit formation. Shell Helix Ultra Professional AP-L 0W-30 is formulated to resist deposit formation and maintain clean engine internals. The oil successfully passes several engine cleanliness tests including the Sequence VH sludge test, the DV6C oil dispersion test and the M271 engine sludge test, demonstrating its ability to maintain clean internal surfaces and support long-term engine performance.
Shell Helix Ultra Professional AP-L 0W-30 is also designed to support modern emission control systems. Its formulation is suitable for engines equipped with diesel particulate filters and gasoline engines fitted with three-way catalytic converters. By helping reduce deposit formation within emission systems, the oil supports efficient exhaust gas flow and helps vehicles comply with Euro 6 emission standards.
The oil meets the demanding Peugeot PSA B71 2312 specification, which requires lubricants to pass a series of manufacturer-specific tests including the DW10C endurance test, the DW10B wear test and EP6CDT endurance testing for gasoline direct injection engines. It also meets the ACEA C2 industry specification, confirming its ability to deliver reliable lubrication performance in modern fuel-efficient engine designs.
Physical characteristics include a kinematic viscosity of approximately 54.42 mm²/s at 40°C and 9.84 mm²/s at 100°C with a viscosity index of around 169. The oil has a density of approximately 844 kg/m³ at 15°C, a flash point of approximately 236°C and a pour point of approximately –45°C. These properties support reliable lubrication performance across a wide range of operating temperatures and driving conditions.
