Maintenance

When should you change your car's oil?

Changing the oil at the right intervals is one of the most important things you can do for your engine's lifespan. Here's when it should happen, and why it matters more than many people think.

Engine oil is one of the most important, yet most overlooked, parts of your car's maintenance. Many drivers are unsure when the oil actually needs changing, and what the consequences are if you wait too long. This guide gives you a clear answer.

Why is engine oil so important?

Engine oil ensures your engine runs optimally. It has several important jobs:

  • Lubricates the engine's moving parts.
  • Reduces friction and wear.
  • Cools the engine.
  • Removes dirt and particles.

Over time, the oil breaks down and loses its properties. That's why it needs to be changed regularly. An oil change is a fixed part of our service check in Rødovre.

When should you change the oil?

As a starting point, it's recommended to change the oil:

  • Every 10,000 to 15,000 km.
  • Or at least once a year.

But it also depends on several factors.

Driving pattern

  • Short trips wear on the oil more.
  • City driving often requires more frequent changes.
  • Motorway driving is normally less demanding.

Car type

  • Newer cars can often go longer between changes.
  • Older cars typically need more frequent service.

Oil type

  • Synthetic oil usually lasts longer.
  • Cheaper oil breaks down faster.

Signs your car needs an oil change

Your car often gives its own signals when the oil is wearing out:

  • The check engine light comes on.
  • The oil is dark and dirty.
  • The engine is noisier than normal.
  • The car loses power.
  • Increased fuel consumption.

If you experience any of these signs, you should get the car checked quickly.

What happens if you don't change the oil?

Skipping oil changes can get expensive. Over time it can lead to:

  • Increased wear on engine parts.
  • Overheating.
  • Reduced performance.
  • Expensive repairs.

In the worst case, the engine can suffer permanent damage, which can cost far more than a regular oil change.

Why regular maintenance matters more than you think

An oil change isn't just a small thing. It's one of the most important investments in your car's lifespan.

Regular maintenance:

  • Extends the engine's lifespan.
  • Gives better fuel economy.
  • Reduces the risk of unforeseen repairs.
  • Increases the car's resale value.

In short: it saves you money in the long run.
