When should a diesel oil change be performed?

Regular maintenance of diesel-powered vehicles is essential to keep them running smoothly and extend their service life. Among the various maintenance tasks to be carried out, the oil change occupies a crucial place. But when exactly should this operation be carried out on a diesel engine?

What is motor oil and what does it do?

Motor oil is an essential liquid that circulates in a car’s engine. It plays a number of key roles in the engine’s operation and longevity. First and foremost, it acts as a lubricant. By circulating between the various engine parts, it reduces friction, thus limiting premature wear of these parts.

Engine oil also has a cooling function. It absorbs and dissipates the heat produced by the engine during operation, preventing overheating which could damage the engine. Finally, it has a cleaning function. In fact, as it circulates, it collects impurities and debris generated by wear and tear on parts, helping to keep the engine clean. Not all motor oils are the same. They can vary in terms of viscosity, composition and additives, and some are specifically designed for diesel engines.

Identifying the right time for a diesel oil change

Determining the ideal time for a diesel oil change is often based on several criteria. Mileage is a key indicator: an oil change is generally carried out every 7,000 to 20,000 kilometers, according to the manufacturer’s recommendation. However, the age of the vehicle and the type of driving also play a role. An older vehicle, or one used for long and frequent journeys, may require an oil change earlier.

A maintenance indicator on the dashboard may signal the need for an oil change. The warning light usually comes on when it’s time to check the oil level and color. An oil color that’s too dark can indicate the need for an oil change. Finally, if you’re planning a long trip, we recommend a preventive oil change to avoid any complications during the journey.

How do I know when it’s time for an oil change?

There are several signs that can tell you it’s time to change the oil in your diesel car. Firstly, the oil change light on the dashboard may come on. It’s vital not to ignore this light, as it usually indicates that the oil level is low.

Another sign is the color of the engine oil. If you find that the oil has become black and dirty, it means that it has lost its lubricating and cooling properties, and that it’s time to replace it. On the other hand, if your engine runs erratically, if you notice starting problems, vibrations or a loss of power, this may be an indicator that the engine oil needs changing.

Finally, if you often drive in difficult conditions such as extreme temperatures, dusty environments or traffic jams, more frequent oil changes are recommended.
