What Type of Engine Oil Should Be Used for a New Car
2 Answers
It is recommended to use full synthetic engine oil. Synthetic engine oil can make the car more durable, more powerful, reduce the frequency of oil changes, and also save on gasoline expenses. Therefore, although the price of synthetic oil is 1-2 times more expensive than ordinary mineral oil, it is still the best choice for many car owners. Currently, engine oils on the market can be simply divided into two types based on the base oil: 1. Mineral oil 2. Synthetic oil. Synthetic oil can be further divided into semi-synthetic and full synthetic oils. The biggest difference between mineral oil and synthetic oil lies in the fact that synthetic oil has a wider temperature range for use, a longer service life, and higher costs. For the same oil film requirements, synthetic oil can achieve this with a lower viscosity, whereas mineral oil requires a relatively thicker viscosity compared to synthetic oil to meet the same requirements. In the same working environment, synthetic oil has a much longer service life than mineral oil, hence the higher cost. However, when comparing the number of oil changes, it is not much higher than mineral oil.
I just got a new car and am particularly concerned about oil selection, as it directly affects engine lifespan and performance. The owner's manual is my primary reference, usually specifying grades like 0W-20 or 5W-30. It accounts for the special needs during the new car break-in period—using the wrong oil can accelerate wear or reduce fuel efficiency. I also checked the impact of ambient temperatures—cold weather requires oil with good low-temperature fluidity to protect the engine during startup. Additionally, I often discuss with friends how synthetic oil is more eco-friendly and fuel-efficient for new cars. After all, driving is a long-term investment, so don’t compromise by switching brands randomly. Always follow the manual, especially during the first few thousand kilometers, and check the dipstick regularly to avoid issues.
