This is one of the questions we get asked most often, and the answer isn't the same for everyone. Here's how to figure out the right interval for your vehicle.
The general rule
Most manufacturers recommend an oil change every 8,000 to 12,000 km, or once a year — whichever comes first. But this number varies based on two main factors: the type of oil used and your driving style.
Synthetic vs conventional oil
Modern synthetic oil generally lasts longer than conventional oil — up to 12,000-16,000 km in many cases — because it resists thermal breakdown better. Conventional oil usually holds up around 5,000-8,000 km. If you're not sure which is in your engine, the sticker left from your last oil change usually says.
Your driving style matters
If you mostly do short city trips, frequent stops, or drive in heavy traffic — that's what's called "severe driving." Oil breaks down faster under these conditions than on long highway trips. If that's you, aim for the lower end of the recommended range rather than the higher end.
Signs it's time, even before the expected mileage
- The engine oil light comes on the dashboard
- The oil on the dipstick is very dark or has a gritty texture
- An unusual engine noise, rougher than before
- A burnt oil smell in the cabin
What happens if you wait too long?
Oil loses its ability to properly lubricate and cool the engine over time. Waiting too long can speed up wear on internal engine components — a potentially far more costly repair than a routine oil change.
