Shell Helix Ultra Professional AM-L 5W-30
Shell Helix Ultra Professional AM-L 5W-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 combined with carefully balanced additive technology to provide excellent engine protection, improved fuel efficiency and reliable performance across a wide range of operating conditions. It has been specifically engineered to meet the requirements of modern engines produced by manufacturers such as BMW and Mercedes-Benz while also complying with major industry performance standards.
One of the key advantages of Shell Helix Ultra Professional AM-L 5W-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 deliver improved fuel economy while maintaining strong lubrication performance.
The oil also provides strong protection against engine wear and corrosion. Engine components such as pistons, camshafts and bearings operate under high loads and temperatures, particularly in modern high-output engines. Shell Helix Ultra Professional AM-L 5W-30 forms a durable lubricating film that reduces metal-to-metal contact between moving components. The oil successfully passes demanding wear protection tests including the Sequence IVB valvetrain wear test and the Sequence VIII bearing corrosion test, confirming its ability to provide reliable protection in demanding operating conditions.
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 AM-L 5W-30 is formulated to resist deposit formation and maintain clean internal engine components. The oil successfully passes several engine cleanliness tests including the Sequence IIIG piston deposit test, the Volkswagen TDI piston cleanliness test and the Sequence VH sludge test. These results demonstrate its ability to maintain clean internal surfaces and support long-term engine performance.
The oil also provides strong soot control, which is particularly important in diesel engines. Soot particles generated during combustion can accumulate in the oil and contribute to deposit formation if not properly dispersed. Shell Helix Ultra Professional AM-L 5W-30 effectively disperses soot particles, helping maintain oil cleanliness and ensuring consistent lubrication performance throughout the oil drain interval.
Shell Helix Ultra Professional AM-L 5W-30 is approved against the demanding BMW Longlife-04 and Mercedes-Benz MB-Approval 229.51 specifications. These specifications require lubricants to pass a range of manufacturer-specific tests evaluating engine wear protection, sludge control, fuel economy and overall lubrication performance. The oil also meets ACEA C3 and API SN industry performance standards, confirming its suitability for a wide range of modern gasoline and diesel engines.
Physical characteristics include a kinematic viscosity of approximately 69.02 mm²/s at 40°C and 12.11 mm²/s at 100°C with a viscosity index of around 174. The oil has a density of approximately 836.1 kg/m³ at 15°C, a flash point of approximately 238°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.
