Is it possible to switch to different engine oil?

It is possible to switch to engine oils of different brands. Definition of engine oil: Engine oil refers to the lubricant specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. The base oils used in modern engine oils are composed of hydrocarbons, poly-alpha-olefins (PAO), and polyinternal olefins (PIO), all of which are organic compounds consisting solely of carbon and hydrogen. Some high-grade engine oils may contain up to 20% esters. Functions of engine oil: There is rapid relative sliding between pistons and cylinders, as well as between main shafts and bearing bushes. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby achieving the goal of reducing wear.
I've been in the auto repair industry for over a decade, and switching different engine oils is acceptable, but it must be done carefully. I've seen many car owners use the wrong oil to save money, leading to engine wear. The key to engine oil lies in matching the viscosity and certification standards with the vehicle manual requirements. For example, Japanese cars are suitable for low-viscosity oil, while German cars may require high-viscosity oil. Using incompatible oil can accelerate component aging, causing oil leaks or noise issues. During regular maintenance, I always advise car owners to check the oil specifications first and not blindly choose cheaper options. Compatible synthetic or semi-synthetic oils pose lower risks when changing, extending engine life while saving money. Remembering the oil change interval is also crucial to avoid accumulating problems from delayed replacements.
