How Often Should a BMW 3 Series Be Serviced?

[LaLogan]

BMW 3 Series should be serviced every 10,000 kilometers. Below are some maintenance precautions: Regular air filter cleaning: Pay attention to cleaning the car's air filter frequently, as it directly affects fuel consumption. During the operation of the car's internal combustion engine, dust and other impurities will continuously mix into the engine oil, while the oxidation effect of air and combustion exhaust gases on the engine oil will gradually form colloids or sludge. This not only accelerates the wear of parts but also easily causes oil passage blockage. Therefore, it is necessary to clean the car's air filter regularly until it is replaced with a new one. Tire pressure calibration: Low tire pressure can lead to abnormal wear or internal damage to the tires, while high tire pressure may cause the tires and rims to deform due to impacts from uneven road surfaces, and may even lead to blowouts. Tire pressure must be checked regularly. Apart from the spare tire, the other tires should be checked at least once every two weeks, and the tire pressure check must be conducted when the tires are cool. Otherwise, high temperatures can increase the tire pressure, resulting in inaccurate measurements.
