5W40, 10W40... MAIS QUELLE HUILE JE DOIS CHOISIR ?

Oil is is a crucial lubricant in engine operation oilso how do you choose the right oil?

What is it used for?

Oil is used to lubricate the engine. It protects friction parts and prevents moving parts from overheating. It cools parts and absorbs heat (up to 400°C). Oil also also keeps the engine clean and protects it from corrosion.

With the number of kilometers covered, the oil becomes clogged and no longer protects the engine sufficiently. To ensure your engine's longevity, long-life oil must be changed every 2 years, conventional or every 20,000 kilometers on average.

In some cases, choosing the right oil for your vehicle saves fuel and reduces pollutant emissions.

Which oil is right for me?

In fact, lubricants are neither good nor bad. For newer vehicles, the right oil can usually be found in your vehicle's service manual (which will tell you the quality and viscosity of the oil) oil your engine needs).

In the absence of a service manual, you should rely on the viscosity of the oil viscosity that corresponds to your vehicle type, driving habits and age.

In a nutshell, they fall into three main categories: synthetic, mineral and semi-synthetic, which are a mixture of the first two.

Good to know!

On each can, there's a number, the letter W, and another number (e.g. 5W40). This is the viscosity index.

The closer the first number is to 0, the more fluid it becomes at low temperatures, making it easier to start up. The higher the number after the W, the thicker the thermal oil film, protecting and sealing the engine. To ensure immediate protection each time the engine is started, the choice of cold viscosity grade is crucial. The finer the viscosity, the faster the engine refueling time.
