5W‑40 Engine Oil
High-performance engines, vehicles exposed to increased thermal stress and many European manufacturers rely on 5W-40 because it maintains a stable oil film even under demanding conditions.
Benefits of 5W-40 Engine Oil
Vehicle Compatibility
5W-40 is commonly used in high-performance gasoline and diesel engines. Manufacturers such as Mercedes-Benz, BMW, Renault, Peugeot, Fiat, Opel and many Asian brands frequently specify this viscosity. Always follow the manufacturer’s approvals.
Why Viscosity Matters
Viscosity determines how the oil flows under cold and hot conditions. 5W-40 remains fluid enough at low temperatures while providing a particularly stable oil film at high operating temperatures – ideal for demanding engines and dynamic driving.

FAQ – Frequently Asked Questions About 5W-40 Engine Oil
What does 5W-40 mean in engine oil?
The rating describes the oil’s viscosity. “5W” indicates cold-flow performance, while “40” refers to the oil’s stability at operating temperature.
Which vehicles use 5W-40?
Many modern and high-performance gasoline and diesel engines. It is especially suitable for vehicles exposed to high thermal loads.
Can I use 5W-40 instead of 5W-30?
Only if approved by the vehicle manufacturer. While 5W-40 offers more stability at high temperatures, using the wrong viscosity can cause issues.
Is 5W-40 suitable for older engines?
Yes, many older engines benefit from the higher temperature stability and robust oil film.
How often should 5W-40 engine oil be changed?
Follow the manufacturer’s recommendations – depending on the model, either fixed intervals or long-life service intervals.
