Car Engine Oil: The exact time and kilometers to change a car's engine oil depends on the engine type, oil type and driving conditions. However, it is generally recommended to change the engine oil every 7,000 to 10,000 kilometers. Some car manufacturers and service manuals may extend this interval to 5,000 kilometers, especially if you regularly drive in difficult conditions (such as off-roading or heavy traffic).

When and why should engine oil be changed?

Preventing Overheating: Engine oil helps keep the engine cool. When oil becomes dirty or old, it loses its ability to dissipate heat, which can cause the engine to overheat.

Less wear and tear: Regular oil changes increase the lifespan of the engine as it reduces wear and tear inside the engine.

Disadvantages of not changing engine oil on time:

Engine wear: If you don't change the oil in time, wear increases between the engine's moving parts, which can lead to early engine failure.

overheating: Old oil cannot provide adequate cooling to the engine, causing the engine to overheat, affecting engine performance.

Decrease in car performance: Engine power and mileage reduces. If the oil becomes too dirty, carbon may accumulate inside the engine, due to which the engine will not function properly.

Engine Jamming: If the oil is not changed for too long, the engine can completely seize up, requiring engine repair or replacement, which can be very costly.

Extended Oil Interval:

Some modern cars use synthetic oil, which can last longer than regular engine oil. In such a situation, engine oil can be used for 10,000 to 15,000 kilometers or more, but for this the advice given in the car manual should be followed.

Driving conditions also matter:

When driving in a city (heavy traffic with frequent stop-and-go traffic) the engine is under greater stress, so the oil may need to be changed sooner.

Driving on the highway requires continued smooth operation of the engine, so the oil can last longer.

Therefore, it is very important to change the engine oil on time as per the instructions given in your car manual.
