When Should Engine Oil Be Replaced Based on Its Remaining Life?

[HavenAnn]

Engine oil should be replaced when its remaining life falls below 20%. However, this should also be determined based on the settings of the vehicle's onboard computer. When the onboard computer is properly configured, it will issue a reminder once the engine oil's service life reaches the replacement threshold. It is recommended that car owners replace the oil promptly to prevent abnormal engine wear during driving, which could affect normal operation and shorten the engine's lifespan. Precautions for oil replacement: 1. Choose engine oil according to the engine's requirements. Do not use high-grade oil in a low-performance engine or low-grade oil in a high-performance engine. Select oil that matches the engine specifications. 2. Opt for multi-grade oil, which offers advantages such as fuel efficiency, extended service life, and high performance, providing better protection for the engine. 3. The oil level should be slightly below the mark on the dipstick; avoid overfilling. 4. Select oil with different viscosities based on the engine's operating conditions. 5. If switching from premium or mid-grade oil to regular oil, first drain all the existing oil and thoroughly clean the lubrication system to prevent mixing.
