Generally speaking, minor alternates with major maintenance, and the frequency depends on the manufacturer's schedule. Many manufacturers recommend performing a major maintenance every 20,000 kilometers. Below is an introduction to car maintenance: 1. Under normal circumstances, changing the engine oil and oil filter is a mandatory task for every maintenance. Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of the oil is significantly shortened, and its performance deteriorates substantially. Over time, it can no longer protect the engine effectively. The oil filter is designed to prevent impurities from mixing with the oil, which can cause oxidation and lead to the formation of sludge and clog the oil passages. 2. Major maintenance builds upon minor maintenance. In addition to replacing the engine oil and oil filter, it also includes replacing the air filter and fuel filter. These two filters serve to filter dust from the air and impurities from the fuel, respectively. The proper operation of the engine relies on the appropriate use of various maintenance products. If the oil and the three filters are not replaced in time after reaching their service limits, it will adversely affect the engine's performance.

I've been driving for over a decade, and major really depends on your driving habits. Since I commute daily and accumulate high mileage, I usually do a major service every 30,000 kilometers. This includes changing the engine oil, oil filter, spark plugs, and also checking the brake discs and cooling system. If you drive less frequently, like keeping the car in the garage, then do it at least every two years to prevent fluid deterioration or part aging. Remember, regular maintenance helps avoid excessive engine wear and saves you from costly repairs later. I stick to this schedule, and my car runs smoothly while extending its lifespan. Never delay too long, or you might face safety issues like brake failure or tire blowouts.

The interval for major depends on the vehicle model and actual usage. For example, my SUV is more durable than a family sedan, and if I frequently drive on highways, I check it every 30,000 kilometers or so. However, different road conditions have a significant impact: frequent stop-and-go traffic in cities causes faster wear, so maintenance should be done earlier; smooth driving in suburban areas allows for a slight delay. Major maintenance mainly involves replacing basic components like air filters and power steering fluid—it's best to refer to your vehicle's manual. I keep regular records of my trips to plan easily and avoid unexpected breakdowns. Long-term neglect can lead to increased fuel consumption or even major engine repairs, so adjusting based on driving conditions is more reliable.

As someone who prioritizes family safety, I believe major should never be taken lightly. It involves critical components like brakes and tires, and I insist on a comprehensive inspection every two years or every 20,000 kilometers. This includes checking the braking system, suspension components, and fluid replacements. Delaying maintenance could lead to accidents, such as brake slippage in rainy conditions, which poses a threat to everyone in the vehicle. I regularly monitor dashboard alerts or maintenance lights and head to a professional shop at the first sign of an issue to ensure everything is in order. This habit gives me peace of mind while driving, especially during long trips.

From a cost-saving perspective, it's essential to schedule major at reasonable intervals. I perform a major service every 20,000 kilometers, replacing routine parts like engine oil and filters, which costs just a few hundred yuan. Skipping regular maintenance can turn minor issues into major failures, potentially multiplying repair costs several times over. I keep track of each service date in my phone's app for easy reminders. Neglecting maintenance—for example, running out of engine oil and causing engine damage—could lead to losses amounting to thousands of yuan. My advice is to plan according to your budget; don't save small sums only to lose big money in the long run—it's more economical overall.

With modern technology, major has become smarter. My car has an onboard system reminder function, recommending a comprehensive service every 30,000 kilometers. This includes checking electronic components such as sensors and batteries, combined with basic item replacements. New technologies like remote diagnostics can help with early warnings, but ultimately, manual inspection is still required. I find this approach hassle-free and adaptable to different driving modes. Neglecting it may lead to instrument malfunctions or starting issues, affecting daily use. Developing regular habits ensures better vehicle performance.
