does not necessarily have to be performed every 5,000 kilometers, as a 5,000-kilometer service typically involves an oil change and inspection of the vehicle's functions. Below are relevant details about maintenance: 1. Definition: Automobile maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle upkeep. 2. Scope: Modern vehicle maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other related areas. 3. Purpose: The goal of vehicle maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent malfunctions, slow down the deterioration process, and extend the service life.

After driving for ten years, I finally realized that the 5000-kilometer interval isn't set in stone! Today's engine oil technology is far superior to what it was twenty years ago, especially full synthetic oils. Manufacturer manuals clearly state intervals of 8000-15000 kilometers for oil changes. My own car's manual specifies maintenance at 12000 kilometers, yet the dealership keeps pushing for 5000-kilometer visits—clearly just trying to make more money on service fees. What really matters is your driving conditions: frequent stop-and-go traffic or mountain driving may require more frequent oil changes. Before each oil change, I always check the dipstick—if the oil is black or contains metal particles, then it's truly time for a change. Don't let shops trick you into unnecessary spending.

You youngsters might not know that the 5,000-kilometer standard is an outdated rule from twenty years ago! Modern cars now use full synthetic oil, and German cars generally require at 10,000 kilometers. My neighbor's BMW manual clearly states an oil change interval of 15,000 kilometers. I've seen too many people fall for dealership tricks during repairs—getting talked into changing oil at just 6,000 kilometers. Remember these three key points: always check your car's maintenance manual for the most accurate information; full synthetic oil can definitely last 10,000 kilometers; cars that frequently drive on highways actually have more durable oil than those stuck in city traffic every day.

A friend who works in auto repair taught me a super simple way to check oil life: pull out the dipstick, drip the oil onto a filter paper, and if the oil stain separates into three layers, it's still good to use. Nowadays, full synthetic oils are incredibly durable—I tried going 12,000 km in my Accord before servicing, and the engine was still quiet. Special reminder for EV owners: items are completely different—electric cars don’t need oil changes. For hybrids, just follow the engine mileage. Don’t fall for repair shops’ scare tactics; over-maintenance harms your car and wastes money. Once, I saw a mechanic pour freshly changed oil into a recycling bin, only to sell it to the next customer. Tsk tsk.

When I first bought a car, I foolishly insisted on every 5,000 km. It wasn't until a business trip to Germany when the car rental company told me their vehicles were serviced every 30,000 km! Now I know better: mineral oil does need changing every 5,000 km, but semi-synthetic lasts 7,500 km, and full synthetic can go 10,000 km or more. My SUV's manual even specifies a 10,000 km oil change interval. Here's a money-saving tip: buy certified genuine oil online yourself and only pay for labor at the shop—you'll save half the cost. Turbocharged cars are best with full synthetic, while naturally aspirated engines do fine with semi-synthetic.

A friend in the auto trade secretly told me that 4S shops love pushing packages because engine oil is the most profitable. What you should really focus on are these key points: Get the first maintenance for a new car done on time, don't delay; before the warranty expires, follow the manual's maintenance requirements strictly, or the manufacturer will deny claims; for classic older cars, you should actually shorten the maintenance intervals. I never dare to use semi-synthetic oil in my turbocharged car—full synthetic oil still shows excellent oil film resilience even after 10,000 kilometers. The funniest thing is seeing people getting talked into engine cleaning right after the break-in period, with mechanics shaking their heads saying it's purely a money grab.
