What are the three types of routine vehicle maintenance?

Vehicle maintenance is divided into three types: primary maintenance, secondary maintenance, and tertiary maintenance. The purpose is to restore the vehicle's performance to its optimal condition, prevent minor issues from becoming major problems, ensure the vehicle's safety, and achieve better fuel efficiency and a longer service life. Primary maintenance focuses on tightening and lubrication, addressing certain weak points that may appear after the vehicle has traveled a certain mileage. This ensures the vehicle continues to meet the technical conditions for normal operation. The main tasks include tightening connecting parts, lubricating major components, and making necessary adjustments based on visual inspections. Secondary maintenance centers on inspection, adjustment, and lubrication, providing a more thorough and detailed comprehensive check and adjustment of the vehicle. The goal is to maintain the vehicle's good operational performance over a longer period. Key tasks include inspecting the condition of components, addressing any identified faults or potential issues, making necessary adjustments, and implementing seasonal measures (such as changing lubricants and addressing cooling or heating needs). Tertiary maintenance focuses on disassembling, cleaning, inspecting, adjusting, and eliminating potential issues within assemblies. It involves a deeper and more thorough consolidation of the vehicle's normal operational performance, ensuring the vehicle operates normally between two tertiary maintenance intervals.
Over the years of driving, I've summarized that routine car maintenance is mainly divided into three levels. The basic maintenance is the most fundamental and needs to be done almost every time, where engine oil and the oil filter must be replaced, the oil pan bolt is tightened, and the mechanic will also use a computer to check the car's condition. The intermediate maintenance is done every 20,000 to 30,000 kilometers, where besides changing the oil and the three filters, spark plugs and brake fluid also need to be replaced as needed. The comprehensive maintenance is the most thorough, involving things like transmission fluid, coolant, and even the timing belt. I remind everyone not to wait until the car has problems to do maintenance; preventive maintenance is the way to save money and hassle. I always keep a maintenance manual in my car, checking what needs to be done when it's time, so I'm less likely to be tricked by repair shops into spending extra money.
