Regular oil service is crucial for maintaining the health of any car, especially newer models. While some manufacturers suggest that modern engines can go up to 30,000 km between oil changes due to advancements in oil technology and engine design, this can be risky for several reasons:
1. **Engine Longevity**: Oil lubricates the engine and prevents wear by reducing friction between moving parts. As oil degrades over time, it becomes less effective, leading to increased engine wear, which can reduce the lifespan of your car.
2. **Oil Contamination**: Even with synthetic oils, contaminants like dirt, metal particles, and combustion byproducts accumulate in the oil over time. These can harm the engine if not removed regularly. More frequent oil changes ensure that these contaminants don’t have time to cause damage.
3. **Driving Conditions**: The recommended interval of 30,000 km often assumes ideal driving conditions—consistent speeds, mild weather, and minimal stop-and-go traffic. However, most drivers experience more demanding conditions, such as short trips, frequent cold starts, or heavy loads, which accelerate oil degradation and make more frequent oil changes necessary.
4. **Turbocharged Engines**: Many newer cars are equipped with turbocharged engines, which operate at higher temperatures and pressures. These engines place greater demands on the oil, making it crucial to change the oil more frequently to prevent turbocharger and engine damage.
5. **Warranty Compliance**: If your car is still under warranty, following a shorter oil change interval may be required to keep the warranty valid. Failing to adhere to recommended maintenance can void your warranty.
6. **Resale Value**: Keeping a strict maintenance schedule, including regular oil changes, can help maintain your car’s resale value. Prospective buyers or dealers often view a well-documented maintenance history as a sign that the car has been well cared for.
While 30,000 km might be acceptable under specific conditions, many experts and mechanics recommend more frequent oil changes, typically every 10,000 to 15,000 km, depending on the car and driving habits. This ensures the engine stays well-lubricated, clean, and efficient, ultimately saving you money on repairs and extending the life of your vehicle.
