How often car oil change

Your mechanic has asked you if you want to change your engine oil, and you have no idea what to tell him? It's normal, it's difficult to know exactly when it's time to change the oil. A few years ago, the rule was to change your oil every 5,000 kilometres.

But is that the case? In fact, the frequency of an oil change varies a lot, and depends on the age of the vehicle, how often it's used, the environment in which it's driven, and so on.


Why should I change my vehicle's oil?

Oil plays a key role in the proper functioning of an engine and should not be neglected. It has several functions: lubrication (to prevent friction between engine parts and slow down their wear), protection (by protecting metal parts from corrosion), cleaning (by capturing deposits and taking them to filters) and cooling (in places where the coolant does not flow). It is one of the fluids that should be replaced regularly to maintain the vehicle manufacturer's warranty and extend the life of mechanical components.


By avoiding friction, engine oil prevents energy loss and saves fuel. A clean oil also extends the life of an engine by protecting the various parts.

This explains the importance of knowing when to change your engine oil. It's best not to wait for the warning light to come on: if you don't change your engine oil, you're exposing it to premature wear. Failure to change the oil can destroy your engine.


When to change the oil?

You've probably heard that you should change your oil every 3,000 miles. Is that really advisable? There is no universal rule, applicable to all vehicles. It all depends on your type of vehicle and how you use it.


Even within one brand of car, the frequency of oil changes varies according to :

  • the model of the vehicle
  • its year of manufacture
  • engine sound type
  • the use of the vehicle.


The simplest way is to follow the standards set by the manufacturer, which can be found in the "owner's manual". By following the recommendations established for your vehicle, you will ensure that you retain your warranty. Once a month, also remember to check your oil level, cold and on a flat surface.

Some cars are able to calculate the oil level using a system that calculates the number of starts and displays the warning light accordingly. But be careful, especially before long journeys: checking the oil level should also be on your maintenance list before you go on holiday.


Note that older cars require more frequent oil changes, while newer vehicles can reach 6,000, 10,000 or even 25,000 kilometres before an oil change is necessary.

Depending on your needs, it is possible to have an oil change every 3 months, every 6 months, or more! Cars that drive mainly in the city and all day long, such as taxis and ambulances, need to have their oil changed more frequently and the 5,000 km rule is sometimes verified. It is also important to change your engine oil regularly when driving in a harsh climate.


What oil should I choose for my engine?

Have you found a garage that does oil changes at a fixed and very advantageous price? Beware. It is not recommended to use the same type of oil for all vehicles. The price of an oil change will vary depending on the type of oil needed and it is difficult to set a price before checking the vehicle's standards.


Make sure you know which oil is recommended for the proper operation of your vehicle. There are :

  • mineral oils,
  • synthetic oils
  • semi-synthetic oils,


All with different viscosity indices. Some manufacturers even have specific oils approved for specific vehicles. Make sure you use the right oil, otherwise your manufacturer's warranty may be affected.

Of course, all these oils, depending on their approvals, have a different price! Find out before you buy your vehicle: depending on the type of motor oil recommended, you'll know if your next oil changes will be expensive...


In addition to oil, it is also important to choose the right filters. Indeed, economical filters will seem like a good investment at first, but they do not accept synthetic oils and will not filter anything. Filters made of a specific material are needed to allow synthetic oil to pass through properly. Ask your Point S Auto Centre for more information.


Ultimately, it's essential to regularly monitor your engine oil level so you know when to schedule your next oil change. Once the appointment is made, your Point S Auto Centre can tell you which oil is recommended for your vehicle. And remember, a healthy engine depends on quality oil and filters!
