Shell Helix Ultra Professional AF 5W-30
Shell Helix Ultra Professional AF 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 and carefully balanced additive technology to deliver 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 from manufacturers such as Ford and Jaguar Land Rover, while also complying with leading industry performance standards.
One of the key advantages of Shell Helix Ultra Professional AF 5W-30 is its ability to improve fuel efficiency. The oil’s low viscosity and low friction formulation help reduce internal engine resistance, allowing moving components to operate more efficiently. Testing using the ACEA M111FE fuel economy procedure demonstrates a minimum fuel efficiency improvement of approximately 3 percent compared with industry reference oils. Reduced friction also contributes to smoother engine operation and improved overall engine efficiency.
The oil also provides strong wear protection and engine durability. Modern engines operate under high loads and temperatures, placing significant stress on internal components. Shell Helix Ultra Professional AF 5W-30 forms a durable lubricating film that helps protect engine components such as camshafts, valve train systems and bearings from wear. The oil successfully passes the Sequence IVB valvetrain wear test as well as additional manufacturer-specific durability testing, confirming its ability to provide reliable protection under demanding operating conditions.
Another important benefit of the oil is its ability to maintain engine cleanliness. During engine operation, combustion by-products and degraded oil can lead to sludge and varnish deposits inside the engine. Shell Helix Ultra Professional AF 5W-30 is formulated to resist deposit formation and keep internal engine components clean. The oil successfully passes the Sequence VH sludge test, demonstrating its ability to control sludge and maintain clean internal engine surfaces. This helps maintain engine efficiency and ensures consistent performance throughout the oil drain interval.
The oil also offers strong soot control, which is particularly important in diesel engines. Soot particles generated during combustion can accumulate in engine oil and contribute to deposit formation if not properly managed. Shell Helix Ultra Professional AF 5W-30 effectively disperses soot particles within the oil, helping prevent deposits and maintain oil cleanliness during operation.
Shell Helix Ultra Professional AF 5W-30 is approved against Ford engine oil specifications WSS-M2C913-C and WSS-M2C913-D. It is also approved against Jaguar Land Rover specification STJLR.03.5003 and meets ACEA A5/B5 performance requirements. These approvals confirm the oil’s compatibility with a wide range of modern engines requiring fuel-efficient lubricants.
Physical characteristics include a kinematic viscosity of approximately 52.51 mm²/s at 40°C and 9.62 mm²/s at 100°C with a viscosity index of around 170. The oil has a density of approximately 851 kg/m³ at 15°C, a flash point of around 222°C and a pour point of approximately –39°C. These properties support reliable lubrication performance across a wide range of operating temperatures and driving conditions.
