Shell Helix Ultra Professional AJ-L 5W-30
Shell Helix Ultra Professional AJ-L 5W-30 is a premium fully synthetic motor oil developed to meet the demanding lubrication requirements of modern high-performance diesel engines. The oil is formulated using advanced synthetic base oils combined with carefully selected additive technology to deliver reliable engine protection, improved efficiency and consistent performance across a wide range of operating conditions. It has been specifically designed to meet the demanding technical requirements of Jaguar Land Rover engines that require advanced low-SAPS lubricants.
One of the key advantages of Shell Helix Ultra Professional AJ-L 5W-30 is its ability to support modern emission control systems. The oil is formulated as a low-SAPS lubricant, meaning it contains reduced levels of sulphated ash, phosphorus and sulphur. This helps protect diesel particulate filters and other emission control technologies by preventing ash accumulation that could restrict exhaust gas flow or reduce emission system efficiency. Maintaining clean emission systems helps ensure consistent engine performance and reliable vehicle operation.
The oil also provides strong protection against engine wear. During engine operation, components such as pistons, camshafts and bearings operate under high loads and temperatures. Shell Helix Ultra Professional AJ-L 5W-30 forms a durable lubricating film that helps reduce metal-to-metal contact between moving components. This protective film minimises wear and contributes to extended engine life while ensuring 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 AJ-L 5W-30 is formulated to resist deposit formation and help keep internal engine components clean. Clean engine internals help maintain efficient engine operation, support consistent performance and protect critical engine components over time.
Shell Helix Ultra Professional AJ-L 5W-30 is specifically designed to meet the demanding Jaguar Land Rover engine oil specification STJLR.03.5005. This specification requires lubricants to meet strict requirements for engine cleanliness, wear protection and compatibility with modern emission control systems. The oil also meets ACEA C1 performance requirements and the Ford WSS-M2C934-B specification, confirming its suitability for engines requiring these performance standards.
The oil is also suitable for use in hybrid vehicles and modern engines that require low-viscosity, fuel-efficient lubricants designed to support advanced engine technologies. Its advanced formulation ensures reliable lubrication performance in modern high-efficiency engines operating under demanding conditions.
Physical characteristics include a kinematic viscosity of approximately 63.1 mm²/s at 40°C and 9.4 mm²/s at 100°C. The oil has a density of approximately 848 kg/m³ at 15°C, a flash point of approximately 199°C and a pour point of approximately –36°C. These properties support reliable lubrication performance across a wide range of operating temperatures and driving conditions.
