When to Change Your Engine Oil (And Why It Matters)
Engine oil is the lifeline of your car. It lubricates engine parts, reduces friction, controls temperature, and keeps the engine running smoothly. Changing engine oil at the right time improves performance, mileage, and engine life.
How Often Should You Change Engine Oil?
There is no one-size-fits-all answer, but here are general guidelines:
🔧 For Petrol Cars
-
Every 5,000–7,000 km (mineral oil)
-
Every 8,000–10,000 km (synthetic oil)
🔧 For Diesel Cars
-
Every 6,000–8,000 km
-
Synthetic oil may last up to 10,000 km
👉 Always check your owner’s manual for the manufacturer’s recommendation.

Fresh oil is golden or light brown. If it looks black and thick, it’s time to change.
⚠️ Engine Noise
Loud or rough engine sounds mean poor lubrication.

Old oil increases friction, making your engine work harder and burn more fuel.
⚠️ Oil Warning Light
