What type of oil is generally used for the first maintenance?
4 Answers
Generally, mineral oil or semi-synthetic oil is used for the first maintenance, and it is recommended to change it every 5,000 kilometers or every six months thereafter. Engine oil, also known as engine lubricant, consists of base oil and additives. It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. The first maintenance of a car refers to the initial service after the vehicle leaves the factory. The primary tasks include changing the engine oil and oil filter. During this process, a comprehensive inspection of the vehicle is conducted, which includes checking all lights, fluid levels, functionality of the electrical systems, tire inspection and pressure adjustment, condition of the chassis components, and checking for leaks and proper operation of the engine and transmission.
I've been driving for over a decade and have experienced several first maintenance services. Dealerships typically use the manufacturer-recommended standard engine oil, most commonly semi-synthetic oil like 5W-30 viscosity, as new cars in the break-in period require oil that's neither too thick nor too thin to protect the engine. When I took my new car for its first maintenance, they provided this oil for free without additional charges. Although fully synthetic oils are more advanced and durable nowadays, there's no need to rush upgrading during the first service - the free option is sufficient. I later consulted technicians who explained that factory oil is specifically designed for new car break-in periods to minimize wear risks. I've personally tried upgrading to full synthetic and noticed little difference. The key for first maintenance is entrusting your vehicle to professionals rather than DIY attempts. Regular maintenance also extends vehicle lifespan with peace of mind. In conclusion, sticking with factory-standard oil for first maintenance is definitely the right choice - don't overthink it.
As a new car owner, I was curious about the first maintenance and did some research. Typically, 4S dealerships use original semi-synthetic engine oil for the first service, such as 5W-20 or 5W-30, which has moderate viscosity suitable for new cars. Why this choice? New engines are still breaking in and need lubrication to reduce wear. This type of oil offers good value for money and comes pre-selected by the manufacturer for free installation. According to my research, semi-synthetic oil strikes a balance between protection and cost—unlike mineral oil which is too cheap and less durable, or full synthetic which is too expensive and wasteful. During the first service, the technician also reminded me to check the oil level and replacement records to ensure engine health. Personally, I think there's no need to worry about upgrades for the first maintenance—the free oil already covers basic needs. If you frequently drive on highways, it’s more cost-effective to switch to higher-grade oil during later maintenance. Driving safety comes first, and the first-service oil is the initial safeguard.
The first service for a new car is usually free, using the manufacturer's standard semi-synthetic oil, commonly in the 5W series. This oil is economical and practical, protecting the engine from initial wear. When I got my first service after buying the car, the 4S shop directly added it without asking for details. The advantage is no extra cost, just a basic check. It's recommended not to change the oil yourself, as the factory-supplied oil is designed for new cars, reducing the risk of malfunctions. Regular oil changes are more important to ensure smooth operation. Simply put, that's how the first service oil works—just leave it to the professionals with peace of mind.
