Can you directly add more engine oil when it's insufficient?

Generally, you can directly add more engine oil when it's insufficient. However, the added oil must be of the same brand and type, and mixing different oils is not allowed. Additionally, opened engine oil can be used for topping up if it's within one year, but oil older than one year is basically ineffective and not recommended for use. Below is relevant information about engine oil selection: 1. Choose engine oil based on the engine's requirements. There's no need to use high-grade oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. It's advisable to choose multi-grade oil whenever possible. Multi-grade oil offers advantages such as cost savings, long service life, and high efficiency, providing better protection for the engine. Due to the characteristics of multi-grade oil, you may observe phenomena like premature darkening or lower oil pressure compared to regular oil during use, both of which are normal.
Last time I noticed my car was low on engine oil, so I popped the hood to check the dipstick—after parking on level ground and waiting a few minutes post-shutdown for more accurate oil drainage readings. If it's normal consumption like my car after extended driving, simply top up with the same type of fresh oil. I always use the manufacturer-recommended grade to ensure proper viscosity and avoid engine damage. But stay alert to why it's low—if the level's critically low or there are leakage signs, get it to a shop after refilling, as oil leaks can cause overheating and engine wear. Make it a habit to check the dipstick every two weeks, wiping clean with a tissue for clear readings to nip small issues in the bud. My friend's car had this too—topped up correctly and ran fine afterwards. Safe driving comes first.
