How Often Should a BMW 3 Series Be Serviced?

[OHannah]

BMW 3 Series should be serviced every 10,000 kilometers. Below are the maintenance considerations: 1. Regularly clean the filter: Always pay attention to cleaning the car's filter, as it directly affects fuel consumption. During the use of the car's internal combustion engine, dust and other impurities 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 can also easily cause oil passage blockage. Therefore, the car's filter should be cleaned regularly until a new air filter is replaced. 2. Correct tire pressure: Low tire pressure can lead to abnormal wear or internal damage to the tire, while excessively high tire pressure can make the tires and rims more susceptible to deformation from impacts on uneven road surfaces, and may even cause a tire blowout. 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.
