How Many Kilometers Should a Car's Turbocharger Be Serviced?

Car turbochargers should be serviced every 7,500 kilometers. The working principle of a turbocharged engine is to use the exhaust gases generated during engine operation to drive the turbine. The maintenance process for turbochargers includes: 1. Regularly changing and cleaning the engine oil, air filter, and filter to reduce impurities, which can prevent wear on the turbine blades; 2. If there is abnormal noise from the turbocharger, check if the turbocharger is damaged; 3. Inspect the joint surfaces between the turbocharger and the engine exhaust manifold, and between the turbocharger and the exhaust pipe for any leaks; 4. Check the internal flow channels of the turbocharger, the inner walls of the housing for burrs or protrusions, whether the impeller is clogged with dirt, and if the diffuser section is clogged, to determine if the abnormal noise from the turbocharger is due to system issues requiring repair and inspection.
I think the maintenance interval for turbocharged cars depends on personal driving habits and the vehicle model. I've been driving a turbo car for five years, and based on experience, it's generally appropriate to have it checked every 50,000 to 70,000 kilometers. If I frequently drive on highways or engage in aggressive driving like hard acceleration, I shorten the interval to every 50,000 kilometers; for city commuting, it can be extended to 80,000 kilometers. The main maintenance tasks include changing synthetic oil and filters to ensure the lubrication system runs smoothly. If maintenance is delayed, the turbo can easily overheat or the seals may get damaged, leading to frighteningly high repair costs. My vehicle manual recommends maintenance every 70,000 kilometers, but I also check the oil quality and listen to the engine sound as extra precautions to prevent small issues from becoming big ones. Overall, regular maintenance can make the turbo more durable, saving both hassle and money.
