What kind of engine oil is suitable for private cars?

Private cars are suitable for using fully synthetic engine oil. The advantages of fully synthetic engine oil are introduced as follows: Low evaporation loss of fully synthetic engine oil: Synthetic oil is a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, reduce exhaust emissions, and extend the service life of the catalytic converter. In addition, compared with traditional mineral oil-type engine oil, synthetic engine oil also has excellent chemical stability, good radiation resistance, high oil film strength, and low foam characteristics. Therefore, high-end cars generally choose synthetic engine oil. Strong high-temperature oxidation resistance of fully synthetic engine oil: The thermal oxidation stability of synthetic oil is much better than that of mineral oil-type engine oil, meaning it has a smaller tendency to produce acidic substances and sludge due to oxidation. Under various harsh operating conditions, it can provide appropriate lubrication and effective protection for the engine, thus having a longer service life and ensuring the performance stability of the engine oil during long-term use. In the same working environment, synthetic oil has a much longer service life than mineral oil, so although the cost is higher, the total cost is not much higher than mineral oil after comparing the number of oil changes.
When it comes to choosing engine oil for private cars, I believe the most important step is to first check your vehicle's owner's manual. It contains the manufacturer's recommended oil viscosity and specifications. For example, my own car requires 5W-30 full synthetic oil. With years of driving experience, I've learned that matching the manual is key, as it considers engine design and performance. Secondly, consider your daily driving conditions: if you frequently encounter city traffic jams, choosing lower viscosity oil can reduce friction and improve fuel efficiency; in cold regions, oils starting with 5W or 0W allow for quicker starts in winter. Synthetic oil, though more expensive, offers better engine protection, especially against high temperatures. If on a tight budget, mineral oil works too, but don't forget regular oil changes—typically every 5,000 to 10,000 kilometers—to prevent engine carbon buildup. Also, pay attention to oil brand certifications like API or ACEI standards to ensure reliable quality. In short, selecting oil based on actual needs can make your car run smoother and more worry-free.
For private car oil selection, I usually consider cost-effectiveness and practical performance. For instance, for my daily commuter car, I lean towards fully synthetic oil because it withstands high temperatures and offers long-lasting protection, especially beneficial for stop-and-go city driving. Checking the vehicle manual is the first step—it specifies the optimal viscosity, such as SAE 0W-20 for modern compact cars, which helps reduce fuel consumption. I also pay attention to seasonal changes: opting for higher viscosity in summer to prevent overheating and lower W-rating in winter for easier cold starts. If frequently driving long distances on highways, semi-synthetic oil is a good alternative, balancing cost and performance. Don’t forget to regularly check the oil level and color—cloudiness or darkening signals it’s time for a change. In summary, choosing oil is like dressing—tailor it to fit best, avoiding blind pursuit of cheap or premium options.
