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.

When it comes to daily car maintenance, I particularly focus on cost-effectiveness. Routine maintenance basically has three tiers: The minor service is the cheapest and fastest—just half an hour at the dealership for an oil and filter change, plus tire pressure and light checks. The intermediate service takes half a day, replacing items like the fuel filter and cabin air filter. I usually stock up on these consumables during e-commerce sales to save a lot. As for the major service, done around every 50,000 km, while it costs more upfront, replacing all fluids and thoroughly inspecting the chassis and suspension can prevent costly repairs down the line. Just remember to stick to the maintenance schedule—timely upkeep is always cheaper than repairs.

From a professional perspective, the three-tier maintenance system is highly scientific. Basic maintenance ensures fundamental operation, performed 1-2 times within 10,000 kilometers, primarily involving oil and oil filter replacement, along with checks on brake fluid levels and tread depth. Intermediate maintenance covers a 30,000-kilometer cycle, focusing on replacing the three filters and brake fluid, with tire rotation recommended. At 50,000 kilometers, a comprehensive maintenance is essential, including transmission fluid replacement, timing belt tension inspection, and coolant system freeze point testing. It's advisable to adjust the maintenance intervals based on driving conditions: vehicles frequently driven in dusty areas should have their air filters replaced earlier, while those often stuck in traffic should shorten oil change intervals.

Last week, I had a good chat with the mechanic while taking my car in for maintenance with my kid. The three-tier maintenance system for family cars—routine, intermediate, and comprehensive—makes perfect sense: Routine maintenance is like a health check-up for the car, changing the oil and oil filter is akin to seasonal wardrobe updates; Intermediate maintenance requires more attention to wear-and-tear parts like brake pads and spark plugs, with a special reminder to parents—don’t slack on replacing the cabin air filter; Comprehensive maintenance is like a full-body check-up, where chassis bolts need re-torquing and wheel alignment must be precise. My car gets serviced every six months without fail, and the mechanic said a well-maintained car can have an exceptionally quiet engine even after a decade—it really holds true.

I only noticed during my wife's car's major maintenance recently that three-level maintenance should be adjusted according to seasons. Basic maintenance is essential during summer-winter transitions, especially changing to low-viscosity oil before winter. For intermediate maintenance, I prefer doing it before summer rainstorms, focusing on wiper blades and drainage holes – in humid southern regions, rust prevention for the chassis is also crucial. I schedule deep maintenance in late April every year, switching from antifreeze to regular coolant after winter, which can improve fuel efficiency by 3%. These tips were learned from experienced mechanics, and indeed, our older family car maintained this way shows noticeably lower fuel consumption than neighbors' same-year models.
