What Oil Should Be Changed During the First Car Maintenance?

[EmmettLee]

For the first car maintenance, it is necessary to change to standard original equipment manufacturer (OEM) oil or fully synthetic oil, which can reduce internal engine wear and extend the engine's service life. The time and specific items for the first car maintenance are as follows: Time for the first car maintenance: The first maintenance for a new car is at 5,000 kilometers or six months, whichever comes first. The first maintenance is free, and you can follow the mileage and time specified in the maintenance manual. Specific items for the first car maintenance: Change the engine oil and oil filter, clean the air filter; check whether the levels of various fluids are normal; inspect the generator belt and wiper blades for any damage; check whether the tire pressure is normal and look for signs of uneven wear, bulges, or damage on the tires.

I recently had the first maintenance service for my new car, and the 4S dealership recommended switching to full synthetic oil. They used the 5W-30 grade, which they said is the type specified in the vehicle manual. This is because the engine is still in the break-in period, producing more metal debris, and full synthetic oil offers better lubrication, effectively removing impurities and protecting the engine. If oil changes are not done as specified, it may lead to premature wear or even shorten the engine's lifespan. Most brands provide free original oil for the first service, which is quite convenient. It's recommended to do it on time, usually around 5,000 kilometers. You can also read the owner's manual more often to understand your car model's requirements and develop good habits to make your car last longer.

After years of driving, I emphasize that the first maintenance for a new car must include an oil change, using the type recommended by the manufacturer. Generally, full synthetic oil is the preferred choice, with common viscosities like 5W-30 or 0W-20, as it dissipates heat quickly and protects the engine during break-in. I've personally seen cases where people used mineral oil improperly, leading to engine problems within two years. During the free first maintenance, always opt for the original factory oil—it's hassle-free and reliable. Don't skimp on this small expense by choosing inferior brands. Remember to perform the first maintenance within 5,000 to 10,000 kilometers, and replace the oil filter as well. This ensures the lubrication system works efficiently and significantly extends the vehicle's lifespan.

The first oil change for a new car is of utmost importance. After initial operation, the engine accumulates a significant amount of metal particles. Synthetic oil, with its strong fluidity, can better remove these impurities and protect critical components. I prefer fully synthetic types, and the viscosity should be checked against the manual—5W-30 suits most cases. Brands like Mobil or Castrol are reliable choices. Never skip this step, and remember to replace the oil filter simultaneously to extend maintenance intervals. The right oil prevents overheating and wear, ensuring smooth and efficient engine operation for years to come.
