Changing the oil filter is one of the most common car maintenance operations. Whether they run on gasoline or diesel, all vehicles with a combustion engine have one. Essential to the machine’s proper functioning, here is what the oil filter is for and when to change it.

The role of the oil filter

The oil filter is an essential part of the proper functioning of your engine. The role of this oil filter is twofold: it complements the engine lubricants and ensures the cleaning of the circuit.

As the name suggests, the purpose of the oil filter is to filter and keep the oil clean. In fact, by circulating in the engine, the oil captures the residues linked to its operation and thus prevents them from setting. Therefore, these residues are retained by the oil, which becomes loaded with impurities (dust, scale). The oil filter is then used to maintain these particles that could damage the engine. All the contaminants are thus retained, avoiding the clogging of the machine.

When to change the oil filter?

The oil filter change occurs in principle at each engine oil. The latter is a maintenance operation that you must do regularly. Indeed, when the oil filter is worn or damaged, it no longer performs its filtering role. The oil-laden impurities may then affect the proper functioning of the engine. To find out when to change the oil, refer to the manufacturer’s instructions.

How to change the oil filter?

You can, of course, go to a mechanic who, when replacing the engine, will automatically replace the oil filter. You can also do it yourself.

To do this, you need to bring:

  • a container of suitable engine oil
  • a drain plug gasket;
  • an oil filter;
  • an oil filter wrench;
  • a funnel;
  • a drip tray for used oil.

The advantages of a well-maintained vehicle

Respecting the maintenance schedule recommended by the manufacturer is the guarantee of keeping your vehicle in good condition for a long time. This means going through the garage regularly for an oil change or overhaul, but it protects you from more extensive repairs. Prevention rather than cure is the idea. Having a regular follow-up and an up-to-date maintenance book is also a guarantee of confidence for a future purchase if you wish to resell your vehicle one day.

The electric car an economical alternative?

While the cost of purchasing an electric vehicle is higher than a vehicle equipped with a heat engine, the maintenance costs are lower because they are less frequent. Oil changes, changes of oil filters, replacement of spark plugs, and timing belts disappear. On the other hand, the evolution of tires, brake pads or wiper blades remains relevant. You should add that a maintenance operation specifically concerns electric vehicles. It is the annual check of the condition of the batteries. Despite everything, there is a saving of around 25% on maintenance costs for an electric car compared to gasoline and diesel vehicles.
