5W-40 motor oil

Motor oil with viscosity 5W-40

Engine oil with a viscosity of 5W-40 is a high-performance lubricant that is used in many vehicles to ensure optimum protection and performance. The viscosity of an engine oil describes its fluidity at different temperatures. The first number, ‘5W’, stands for the fluidity of the oil at low temperatures, where ‘W’ stands for winter. A lower number means that the oil remains fluid at cold temperatures and circulates quickly through the engine, which is particularly important to minimise wear during cold starts.

The second number, ‘40’, indicates the viscosity of the oil at operating temperature. A higher value such as 40 indicates that the oil remains thicker at high temperatures, which protects the engine from wear and heat, especially at high speeds or heavy loads. This makes 5W-40 engine oil ideal for vehicles operating under extreme conditions, such as high temperatures or intensive use.

5W-40 engine oil is often used in high-performance vehicles such as sports cars, SUVs and lorries. It offers an excellent balance between cold start properties and protection at high temperatures, which is why it is recommended by many car manufacturers such as Volkswagen, Mercedes-Benz, BMW and Porsche. This oil is particularly suitable for drivers who want high performance and maximum protection of their engine in all conditions, whether in daily city traffic or on the motorway at high speeds.
