Shell Helix Ultra Professional AP-L 5W-30
Shell Helix Ultra Professional AP-L 5W-30 is a premium fully synthetic motor oil developed to meet the demanding lubrication requirements of modern gasoline and diesel engines. The oil is formulated using advanced synthetic base oils combined with carefully balanced additive technology to provide reliable engine protection, improved efficiency and consistent lubrication performance across a wide range of operating conditions. It has been specifically designed to meet the technical requirements of Peugeot and Citroën engines that require advanced low-SAPS lubricants.
One of the key advantages of Shell Helix Ultra Professional AP-L 5W-30 is its compatibility with modern emission control systems. The oil is formulated with reduced levels of sulphated ash, phosphorus and sulphur to help protect diesel particulate filters from deposit build-up. By preventing ash accumulation within the exhaust after-treatment system, the oil helps maintain efficient exhaust gas flow and supports compliance with modern emissions regulations. This makes the oil particularly suitable for diesel engines fitted with particulate filter technology.
The oil also provides strong protection against engine wear. Engine components such as pistons, camshafts and bearings operate under high loads and temperatures during normal engine operation. Shell Helix Ultra Professional AP-L 5W-30 forms a durable lubricating film that helps reduce metal-to-metal contact between moving 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 and lead to sludge or deposit formation over time. Shell Helix Ultra Professional AP-L 5W-30 is formulated to resist deposit formation and keep internal engine components clean. Clean engine internals help maintain efficient combustion, support consistent performance and protect critical engine components during extended service intervals.
Shell Helix Ultra Professional AP-L 5W-30 has been specifically developed to meet the demanding Peugeot PSA B71 2290 specification, which applies to many Euro 5 diesel engines and earlier engine designs. This specification requires lubricants to meet strict standards for wear protection, engine cleanliness and compatibility with emission control systems. The oil also meets ACEA C2 and API SN performance standards, confirming its ability to provide reliable lubrication performance for modern fuel-efficient engine designs.
In addition, the oil meets the requirements of Iveco 18-1811 Class SC1 and is suitable for use in hybrid vehicles where a fuel-efficient low-viscosity lubricant is required. These specifications confirm the oil’s versatility and suitability for a wide range of modern engine technologies.
Physical characteristics include a kinematic viscosity of approximately 59.59 mm²/s at 40°C and 10.2 mm²/s at 100°C with a viscosity index of around 162. The oil has a density of approximately 843.7 kg/m³ at 15°C, a flash point of approximately 233°C and a pour point of approximately –48°C. These properties support reliable lubrication performance across a wide range of operating temperatures and driving conditions.
