When to change and how to know if it has been changed

The oil change is an intervention to be done periodically to extend the life of the engine. It eliminates any impurities present therein while ensuring the lubrication of the various mechanical elements that compose it. When and how to drain?

What is the drain for?

Emptying a car consists of replace engine oil. It must be carried out periodically to prevent corrosion and engine fouling, while keeping it in good working order. Emptying also makes it possible to:

• Reduce fuel consumption;
• Avoid the risk of engine failure over time;
• Improve engine performance;
• Avoid overheating the engine.

When to change the oil?

In general, the oil change should be done at least once a year. It is crucial to respect the manufacturer’s recommendations by referring to the indicator visible on the instrument panel.

For a gasoline vehicle, it is to be carried out every 10,000 to 15,000 km, against 7,000 km for diesel cars. However, the frequency varies depending on the mode of use. The intervals are shorter if the automobile is generally driven in an urban area. In fact, the oil degrades more quickly, loses its viscosity and becomes loaded with metal particles and other impurities.

How do I know if the oil change has been done?

There are many signs that the drain has not yet been performed:

  • The warning light on the dashboard lights up

When the oil pressure warning light comes on, it is necessary to check the oil level as well as its color, which should be amber normally. If it is black, it means that impurities have accumulated inside the tank. The oil takes on a dark shade as the viscosity decreases. An increase in thickening and density is also observed.

  • Black or blue smoke comes out of the exhaust

This emission may result fromlow engine oil level. However, there are other factors to consider as well, such as loss of engine power due to more serious mechanical issues. Thus, it is recommended to carry out a more in-depth diagnosis, to be entrusted to a professional preferably.

  • Abnormal noises coming from the engine

Engine oil is designed for ensure lubrication of the various metallic elements making up the engine while creating a protective layer. This liquid deteriorates over the kilometers traveled. Therefore, when poorly lubricated, these parts that rub against each other generate heat, accelerating their wear. The noises emitted by the engine are louder and louder, and eventually turn into a knocking, even a sort of roar.

In the event that any of these symptoms appear, the drain must be done as soon as possible. It is recommended to contact the nearest garage to check the condition of the filters (oil, fuel and air) and the various mechanical parts that make up the engine. This professional is responsible for taking corrective measures.
