Hi, it’s Patrick. For a petrol car, do the emptying all the 10,000 to 15,000 km or at least once a year is often the right timing to avoid any engine riskExceeding this range significantly increases the risk to engine longevity.
To do immediately:
- Check your engine oil level regularly, especially if you drive in the city.
- Opt for a suitable synthetic engine oil for better protection.
- Plan your next car service so you never miss an oil change.
- Never neglect the oil change indicator; it is a key indicator for engine maintenance.

Why regular oil changes are essential for your petrol car
A little anecdote: a friend went 5,000 km over his oil change interval on his petrol car, thinking it would be fine. As a result, the engine became noisy, and the mechanic’s bill quickly dampened his enthusiasm. Which just goes to show, “a well-oiled engine is a happy engine.”
The correct oil change interval for a petrol car is often between 10,000 and 15,000 kmThis range can be widened or narrowed depending on:
- Driving style (city or highway).
- The age and general condition of the car.
If you mainly drive cityWith frequent stops and starts, aiming for the shortest interval (10,000 km) is safer. However, if you mainly drive on highways, you can consider 15,000 km.
Oil change: a simple 3-step procedure
- Step 1: Drain the used oil by placing a collection tray under the engine.
- Step 2: Replace the oil filter, the essential element for retaining impurities and residues.
- Step 3: Fill with a suitable engine oil, respecting the indicated dosage.

What are the engine risks of exceeding the oil change interval?
Exceeding the oil change interval, even by 1,000 kmExpose your engine to:
- Accumulation of impurities that clog and damage the parts.
- Loss of lubrication, increasing premature wear.
- Risk of overheating due to lower-performance oil.
- Increase in fuel consumption.
For a more significant delay, for example 5,000 km, these problems intensify and can quickly become a mechanical nightmare. So, it’s best to play it safe.
