It mainly depends on the type of engine oil used in the vehicle. There are generally three scenarios. Fully synthetic oil typically requires replacement every 10,000 kilometers or once a year. Semi-synthetic oil usually needs to be changed every 7,500 kilometers or every 7-8 months. Mineral oil generally requires replacement every 5,000 kilometers or every 6 months. Below is a detailed introduction about engine oil: 1. Overview: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, and shock absorption. 2. Composition: Engine oil consists of two main components: base oil and additives. Base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives are used to compensate for and improve the shortcomings of the base oil, providing additional performance characteristics, making them an essential part of lubricating oil.

I've been driving a FAW-Volkswagen car for five years, and the maintenance cycle is usually every 10,000 kilometers or once a year, depending on the model and the owner's manual. For example, with my Sagitar, I make it a habit to go to the 4S shop for maintenance every 10,000 kilometers, mainly to change the engine oil and oil filter, and then check key components like the brakes and tires. If you often drive in city traffic jams or on gravel roads where the engine is under heavy load, you might need to check it every six months in advance to avoid sludge buildup affecting performance. Remember not to miss the first maintenance at around 5,000 kilometers, otherwise the warranty may become void. I delayed it once and almost got fined for clutch repairs. It's best to use original parts during maintenance; although they're more expensive, they're durable and hassle-free. In short, don't find it troublesome—regular maintenance extends the car's lifespan and saves fuel.

Hey, I've been driving my Volkswagen Bora for almost three years now, and a maintenance cycle every 10,000 kilometers or once a year is sufficient. Modern car technology has advanced significantly, no need for excessive fuss. My friend always insists on doing it every 5,000 kilometers, saying it's a waste of money, but I believe sticking to the schedule is safer. Oil quality is crucial—I use full synthetic oil, which lasts longer. When driving, I pay attention to oil level changes. If I do a lot of highway driving, wear is minimal, and I can stretch it to 15,000 kilometers. But if there's a lot of city traffic and congestion, I check the tires and brakes every six months. Once, I missed a scheduled maintenance, and the engine started making strange noises—the repair bill was expensive. The 4S shop reminders are pretty accurate; after their inspection, they even notify me of the next service date. For daily upkeep, I regularly check the car’s condition myself, like addressing odd smells from the AC early to save money. Sticking to the maintenance schedule keeps the car running smoothly and worry-free.

When I first bought my Volkswagen Golf, the 4S store told me to do the first maintenance within 7,500 kilometers or half a year, and then every 10,000 kilometers or once a year. Don't exceed the mileage in the first few years of a new car, otherwise the warranty issues will be troublesome and costly. I just go on time to change the oil filter and other basic items. Newbies don't understand complicated things, but it's much easier to go to a professional shop. After driving for a long time, I found that road conditions have an impact. For example, if you often drive on dirt roads, you may need to check the engine in advance every 8,000 kilometers. Maintenance saves money and gives peace of mind, and the car has fewer problems.
