🔧 HOW IS ENGINE OIL CLASSIFIED?
Engine oils are classified mainly on the basis of:
✅ Viscosity (SAE)
It is the famous acronym such as 5W30 or 0W20 .
-
The first number (e.g. 0W) indicates the cold flow rate.
-
The second (e.g. 20 or 30) indicates the hot fluidity.
The lower the number, the thinner the oil will be.
✅ Base type
-
Mineral → for old cars or cars with simple engines.
-
Semi-synthetic → compromise between quality and price.
-
100% synthetic → ideal for modern engines and high performance.
✅ Specifications and approvals
Each car manufacturer requires oil with precise standards , for example:
-
VW 507.00
-
MB 229.52
-
Fiat 9.55535-GS1
These specifications ensure the compatibility and safety of the engine.
❗ THE IMPORTANCE OF SPECIFICATIONS
It's not enough to choose an oil with the same viscosity (e.g. 5W30): you must always check the specifications required by your car.
Using an incorrect oil can damage the engine or void the vehicle warranty.
This is why lubricant advisors are indispensable tools : they automatically tell you which oil to use , based on your vehicle.
