Shell Helix HX5 15W-40
Shell Helix HX5 15W-40 is a premium multigrade engine oil designed to provide reliable engine protection and consistent performance in a wide range of vehicles operating under everyday driving conditions. The oil is formulated using carefully selected base oils combined with Shell’s active cleansing technology to help maintain engine cleanliness, protect critical components and support efficient engine operation. This formulation is suitable for modern passenger cars as well as older engines that require dependable lubrication performance.
A key advantage of Shell Helix HX5 15W-40 is its ability to help prevent and remove engine sludge. Sludge deposits can build up over time due to combustion by-products and degraded oil, which may reduce engine efficiency and cause increased wear. The oil’s active cleansing technology helps lock away harmful deposits and assists in cleaning up sludge left behind by lower quality lubricants. By keeping engines cleaner, the oil helps maintain smooth engine operation and prolong engine life.
The oil also provides effective protection against wear. During engine operation, moving metal components such as pistons, camshafts and bearings are subjected to high loads and friction. Shell Helix HX5 15W-40 forms a durable lubricating film between these components, helping reduce metal-to-metal contact and minimise wear. This protective film contributes to improved engine durability and helps maintain reliable performance throughout the oil drain interval.
Another important benefit of the oil is its resistance to oil degradation. Engine oils can break down over time due to exposure to heat, oxygen and combustion by-products. Shell Helix HX5 15W-40 is formulated to resist oil degradation, helping maintain its protective properties throughout the service interval. This stability supports consistent engine protection and reduces the risk of deposit formation during extended operation.
Shell Helix HX5 15W-40 also offers excellent fuel flexibility. The oil can be used in gasoline, diesel and gas engines and is compatible with fuels such as biodiesel and gasoline/ethanol blends. This versatility allows it to be used across a wide range of passenger vehicles and light-duty engines operating under different fuel conditions. In addition, the oil provides protection against low-speed pre-ignition (LSPI), a potentially damaging event that can occur in modern turbocharged gasoline direct injection engines.
Shell Helix HX5 15W-40 meets several major industry specifications including API SN PLUS, API SN and API CF, as well as ACEA A3/B3 performance standards. These approvals confirm the oil’s ability to meet the performance requirements of many modern and older engine designs.
Physical characteristics include a kinematic viscosity of approximately 106 mm²/s at 40°C and 14.27 mm²/s at 100°C, with a viscosity index of around 137. The oil has a flash point of approximately 241°C, a pour point of around –45°C and a density of approximately 865.8 kg/m³ at 15°C. These properties support reliable engine lubrication across a wide range of operating temperatures and driving conditions.
