Shell Helix HX7 Professional AF 5W-30
Shell Helix HX7 Professional AF 5W-30 is a high-performance synthetic technology motor oil designed to meet the demanding requirements of modern gasoline and diesel engines. The oil has been specifically developed to meet particular engine manufacturer requirements, including Ford engine specifications. It uses a carefully balanced formulation of high-quality base oils and advanced additives to deliver reliable engine protection, improved fuel efficiency and strong engine cleanliness.
One of the key advantages of Shell Helix HX7 Professional AF 5W-30 is its fuel efficiency performance. The oil has been developed to reduce friction within the engine, helping improve fuel economy during everyday driving conditions. It passes demanding industry fuel economy tests such as the M111FE test with a minimum fuel efficiency improvement of approximately 2.5 percent. The formulation also meets ASTM Sequence VIA and VIB fuel economy requirements, demonstrating its ability to support efficient engine operation and reduced fuel consumption.
The oil also provides excellent engine durability and wear protection. Modern engines operate under high mechanical stress and temperature conditions that can lead to component wear if lubrication performance is insufficient. Shell Helix HX7 Professional AF 5W-30 forms a protective lubricating film that reduces metal-to-metal contact between engine components such as camshafts, bearings and valve train parts. The oil successfully passes several engine wear and corrosion tests including ASTM Sequence IVB for valvetrain wear and ASTM VIII bearing corrosion testing. These results demonstrate its ability to provide dependable protection for critical engine components.
Another important benefit of the oil is its ability to maintain engine cleanliness. Over time, combustion by-products and contaminants can form sludge and varnish deposits inside the engine. Shell Helix HX7 Professional AF 5W-30 is formulated to resist oxidation and deposit formation, helping maintain clean internal engine surfaces. The oil passes stringent oxidation stability and sludge tests such as the Sequence IIIG and Sequence VH engine tests, confirming its ability to keep engines clean and maintain lubrication performance over time.
The formulation also provides strong soot control, which is particularly important for diesel engines where soot particles can accumulate in the lubricant. The oil has been tested for effective soot dispersion using the DV6C oil dispersion test at medium temperatures. This helps maintain oil cleanliness and ensures that soot particles remain suspended in the oil rather than forming harmful deposits on engine components.
Shell Helix HX7 Professional AF 5W-30 is approved for use in engines requiring Ford WSS-M2C-913 A and WSS-M2C-913 B specifications. It also meets API SJ, ACEA A1/B1 and ILSAC GF-2 industry standards. These approvals confirm the oil’s ability to deliver reliable performance across a wide range of compatible vehicles and engine types.
Physical characteristics include a kinematic viscosity of approximately 54.7 mm²/s at 40°C and 9.92 mm²/s at 100°C with a viscosity index of around 170. The oil has a flash point of approximately 230°C, a pour point of approximately –45°C and a density of around 851 kg/m³ at 15°C, supporting reliable lubrication performance across a wide range of operating temperatures.
