What Type of Engine Oil is Best for the First Car Maintenance?

Every vehicle comes with a manufacturer-recommended standard original engine oil. If not specifically specified, using the original engine oil is sufficient for both the first maintenance and subsequent regular services. Types of engine oil: Mineral Oil: Mineral oil is directly refined from crude oil without the addition of other additives. It is suitable for low-displacement, non-turbocharged vehicles or those with infrequent usage, typically around 5,000 kilometers in half a year. If you don't drive often, mineral oil offers the best economic value. Semi-Synthetic Oil: Semi-synthetic oil is a blended product made by mixing mineral oil and full synthetic oil through a compounding process. It offers the best cost-performance ratio and is a great choice for drivers who frequently use their cars. Its oil change interval is around 7,500 kilometers, making it suitable for most vehicle models. Full Synthetic Oil: Full synthetic oil is more expensive compared to the previous two types but offers superior performance. Whether in terms of stability, lubrication, low-temperature performance, or cleanliness, it far outperforms mineral oil and semi-synthetic oil. Its replacement interval exceeds 10,000 kilometers, and many car owners experience noticeable performance improvements after switching to full synthetic oil.

As an extremely meticulous new car owner, I've done a lot of research after purchasing my vehicle. The choice of engine oil for the first maintenance is truly crucial. I specifically checked the owner's manual and found that manufacturers usually specify the oil type, such as 5W-30. The free oil provided by 4S shops during the first maintenance is typically mineral or semi-synthetic oil, which is completely adequate—there's no need to spend extra on upgrades. During the break-in period, metal debris can accumulate in the engine, and timely oil changes are essential to protect precision components. Remember to replace the oil filter simultaneously; otherwise, the oil change is pointless. A friend of mine tried to save money by getting maintenance at a small shop and ended up using off-brand oil, which later caused unusually loud engine noise. I recommend sticking to the 4S shop for the first maintenance and using the manufacturer-recommended oil. Following the manual and going within 5,000 kilometers is the safest approach.

As a car enthusiast, I believe choosing the first service oil depends on viscosity and grade matching. Japanese cars generally use 0W-20 thin oil, while German cars prefer 5W-30. Most importantly, don't randomly change the oil type - new car engine clearances are precisely calculated. Mineral oil can actually handle the first service, but semi-synthetic offers better cleaning. Full synthetic isn't necessary yet; waiting until the second service to upgrade is fine. Interestingly, some luxury brands use full synthetic oil right from the first service, but regular family cars really don't need it. Key reminder: always change the oil filter when changing oil, otherwise it's like breathing through a dirty mask - the maintenance would be wasted.

I remember my first car suffered because I didn't choose the right oil for the initial maintenance. The core purpose of initial maintenance is to remove engine break-in debris, so mineral oil is completely adequate - the free one provided by 4S shops is sufficient. However, some shops may scare you by saying not using full synthetic oil will harm your car, which is purely a marketing tactic. There are three key points to watch: first, verify the specification in the manual; second, confirm the production date to avoid expired products; third, supervise whether the workers truly drain all the old oil. I've seen cases where the drain plug wasn't tightened properly, causing leaks. After initial maintenance, it's recommended to drive about 100 kilometers and check the dipstick - the oil level should normally be at the midpoint between the markers.
