Shell Helix Ultra Professional AJ-L 0W-20
Shell Helix Ultra Professional AJ-L 0W-20 is a premium fully synthetic motor oil developed to meet the demanding lubrication requirements of modern high-performance gasoline engines. The oil is formulated using advanced synthetic base oils combined with carefully selected additive technology to deliver reliable engine protection, improved fuel efficiency and long-term performance. Its formulation is specifically tailored to meet manufacturer requirements for Jaguar Land Rover and Ford engines that require low-viscosity, fuel-efficient lubricants.
One of the key advantages of Shell Helix Ultra Professional AJ-L 0W-20 is its ability to improve fuel efficiency. The oil’s low viscosity and reduced friction characteristics help reduce internal engine resistance, allowing engine components to move more freely during operation. Reduced friction helps engines operate more efficiently, contributing to improved fuel economy and lower fuel consumption during everyday driving conditions. These benefits are particularly important for modern engines designed to meet strict fuel economy and emissions targets.
The oil also provides strong protection against engine wear. During operation, critical engine components such as pistons, camshafts and bearings operate under high loads and temperatures. Shell Helix Ultra Professional AJ-L 0W-20 forms a durable lubricating film that reduces metal-to-metal contact between moving parts. This protective film helps minimise wear and supports long-term engine durability, ensuring reliable performance throughout the oil drain interval.
Another important feature of the oil is its ability to maintain engine cleanliness. Combustion by-products and degraded oil can lead to the formation of sludge and deposits inside the engine over time. Shell Helix Ultra Professional AJ-L 0W-20 is formulated to resist deposit formation and help keep engine components clean. Clean engine internals help maintain efficient combustion, protect critical engine parts and support consistent engine performance over time.
Shell Helix Ultra Professional AJ-L 0W-20 has been developed to meet specific manufacturer requirements. It is approved against the demanding Jaguar Land Rover specification STJLR 51.5122 and also meets the Ford engine oil specification WSS-M2C952-A1. These specifications require lubricants to pass a range of engine performance tests designed to evaluate wear protection, fuel efficiency and overall lubrication performance in modern engine designs.
The oil also meets key industry standards including API SN and ACEA C5. These standards confirm the oil’s ability to provide reliable lubrication performance in modern gasoline engines designed to operate with low-viscosity, fuel-efficient lubricants. Shell Helix Ultra Professional AJ-L 0W-20 is therefore suitable for use in many modern vehicles requiring these performance specifications.
Physical characteristics include a kinematic viscosity of approximately 41.90 mm²/s at 40°C and 8.20 mm²/s at 100°C with a viscosity index of around 174. The oil has a density of approximately 832.7 kg/m³ at 15°C, a flash point of approximately 232°C and a pour point of approximately –60°C. These properties support reliable lubrication performance across a wide range of operating temperatures and driving conditions.
