How to Choose the Right Engine Oil Type for Your Car?
2 Answers
Methods for selecting engine oil types: Temperature and operating conditions are two key criteria for choosing engine oil. In regions with low winter temperatures, opt for oils with a smaller number before the W. For those who enjoy fast driving or own older vehicles, select oils with higher viscosity coefficients after the W. It is recommended to choose from higher-end brands whenever possible. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and wear reduction, aiding in cooling, sealing to prevent leaks, rust and corrosion prevention, and shock absorption. When checking the oil level, note that the dipstick has two marks: a maximum and a minimum. The proper oil level should not exceed the maximum mark nor fall below the minimum mark; it should be between these two marks.
With over a decade of driving experience, selecting the right engine oil model requires combining the vehicle manual with practical knowledge. The owner's manual specifies recommended viscosity, such as 5W-30 which suits most cars—providing sufficient high-temperature protection in summer and quick starts in winter. For older engines, I use high-mileage oil to prevent leaks. Never overlook API standards; SP-grade is the latest for guaranteed performance. I regularly check the dipstick color—if it's too dark, it's time for a change. Driving habits matter too; synthetic oil is better for fuel efficiency and eco-friendliness in stop-and-go city traffic. Avoid cheap off-brand oils—engine repairs cost far more. Remember, changing oil twice a year ensures safety and reliability.
