At what percentage should engine oil be replaced?
1 Answers
Generally, engine oil should be replaced when its remaining life is below 20%. However, this should also be determined based on the settings of the vehicle's onboard computer. When properly configured, the onboard computer will alert you when the oil life reaches the replacement threshold. Below are some common misconceptions about engine oil usage: 1. Only topping up without replacement: Many car owners keep spare oil in their vehicles and top up when oil levels are low. This practice is unwise. While topping up meets the engine's oil quantity requirements, it fails to satisfy the performance requirements. Over time, this can affect normal engine operation and increase the likelihood of abnormal wear. 2. Mixing oils from different brands: Mixing different types of oil can also lead to reduced lubrication. Although the base oils may be similar, different brands and types of oil contain different additives, resulting in varying performance and grades. Mixing oils indiscriminately may cause chemical reactions that degrade oil performance, posing a significant threat to the engine. 3. Using gasoline engine oil in diesel vehicles: This is a major misconception in oil usage. Due to differences in compression ratios between diesel and gasoline engines, diesel engines have higher oil requirements. Using gasoline engine oil in a diesel engine can actually harm the diesel engine.
