How to know the right type of oil for your car?

Oil changes are an essential maintenance operation for your vehicle. But beyond the simple change, it is crucial to know what type of oil is right for your engine. Although the manufacturer's manual remains the reference, there are now online tools to help you with this process. Let's find out together how to identify the right oil for your car.

The importance of engine oil

Oil plays a vital role in the optimal functioning of an automobile. Its main functions are:

  • Lubricate moving engine parts to reduce wear
  • Help maintain an adequate temperature
  • Participate in the cleanliness of the mechanism
  • Regular oil changes are essential to ensure safer and more economical driving. However, it is equally important to choose the best oil for your vehicle.

    The different types of engine oils

    The choice of oil depends mainly on two factors: its composition and its viscosity.

    Regarding the composition, we distinguish three categories:

  • Mineral oil: produced by refining petroleum, it is the most economical but it degrades more quickly.
  • Synthetic oil: developed by chemical processes, it is suitable for many vehicles. More expensive, it retains its properties for longer and can even slightly reduce consumption.
  • Semi-synthetic oil: a mixture of the two previous ones, offering a good balance between price and performance
  • Viscosity, on the other hand, indicates the oil's ability to lubricate depending on the temperatures. It is expressed by two numbers, for example 5W40: the first number represents the viscosity at low temperatures, the second at high temperatures.

    How to Identify the Right Oil for Your Car

    The most reliable method remains to consult the maintenance manual provided by the manufacturer. You will find the specifications of the recommended oil as well as the recommended oil change frequency.

    Alternatively, some websites offer handy tools to help you identify the right oil for your vehicle. For example, Norauto's website offers a service that lets you find the right oil by simply entering your license plate. The tool automatically recognizes the make and model of your car, then offers you a selection of compatible oils.

    Special case of collector cars

    For classic car enthusiasts, it is important to note that classic cars, 30, 40 years old or more, are generally not compatible with modern synthetic oils, despite their superior performance.

    In this case, it is essential to refer to the vehicle's original manual to find out the specifications recommended by the manufacturer at the time.

    The importance of an informed choice

    Choosing the right oil for your engine is not a trivial detail. A suitable oil contributes to:

  • Extend engine life
  • Optimize vehicle performance
  • Reduce fuel consumption
  • Minimize environmental impact
  • Ultimately, taking care to choose the right oil for your vehicle is a wise investment for its longevity and efficiency. Do not hesitate to consult a professional if in doubt, because expert advice can make all the difference in the maintenance of your automobile.
