What type of engine oil is used for the first car maintenance?

[MacHaven]

The first maintenance uses original factory engine oil. The functions of engine oil are: 1. Lubrication and wear reduction; 2. Auxiliary cooling and temperature reduction; 3. Sealing and leakage prevention; 4. Rust and corrosion prevention; 5. Shock absorption and cushioning. Engine oil, also known as motor lubricant, is composed of base oil and additives. It is classified by viscosity into: 1. Four-stroke engine oil; 2. Two-stroke engine oil. The benefits of the first car maintenance include: 1. Ensuring the vehicle is in optimal performance condition; 2. Improving vehicle efficiency and reducing wear on parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Maintaining a clean vehicle appearance and preventing damage.

When I just bought my new car, the first maintenance was an oil change. I specifically asked the technicians, and they said it's best to use full synthetic oil for the first service, such as 0W-20 or 5W-30, because the new engine needs better cleaning and lubrication during the break-in period, and mineral oil might not provide sufficient protection. I must remind you that the manufacturer's manual usually specifies the oil specifications. My car requires synthetic oil, which can extend the engine's lifespan and prevent early wear. Additionally, the first maintenance at the 4S shop is often free, but if you switch to another oil, remember to check compatibility. I think changing the oil early can save a lot on repair costs, as new engines are delicate, and using the wrong oil can easily cause minor issues. In short, following the manual is the most reliable approach—don't try to save money by using cheaper oil.

I was a bit confused during my first car maintenance, so I looked up a lot of information online and learned that synthetic oil is recommended for the first service, especially for new cars. The technician at my 4S dealership told me that new engines require high-end protection, and synthetic oil offers better lubrication, reduces friction, and prevents premature aging of parts. He used the manufacturer-specified oil, saying it ensures warranty coverage. I was initially worried about the cost, but although synthetic oil is more expensive, it lasts longer, making it more cost-effective in the long run. I think beginners should check the manual requirements—some cars can use semi-synthetic oil, but don’t choose randomly to avoid affecting performance. The key is regular checks; if the oil looks dirty, it’s time to change. Regular maintenance keeps the engine healthier anyway.

I prioritize affordability and effectiveness when choosing engine oil for the first maintenance. After consulting with a mechanic, I learned that new cars can use either synthetic or mineral oil, but synthetic oil is more suitable for the break-in period. For example, 0W-20 synthetic oil has high fluidity and is better for the engine. Mineral oil is cheaper but less effective and prone to causing wear. My strategy is based on budget: if money is not an issue, go for full synthetic; if on a tight budget, use semi-synthetic or the manufacturer's recommendation. The key is not to skimp on this expense—investing a little in a new engine saves big on major repairs later. Change the oil on time, roughly every 5,000 to 10,000 kilometers.
