Does a BMW 5 Series oil temperature around 120 degrees have any impact?

[StValerie]

An oil temperature around 120 degrees Celsius in a BMW 5 Series is normal, but temperatures above 120℃ are considered abnormal. Here’s an introduction to the BMW 5 Series oil temperature: 1. Engine: High engine coolant temperature can increase the internal pressure of the cooling system, leading to potential issues. Besides high coolant temperature, the engine oil may also experience elevated temperatures. This is closely related to the antifreeze. 2. Oil Temperature: High antifreeze temperature can also raise the oil temperature (oil temperature is usually higher than coolant temperature). When the oil temperature is too high (coolant temperature also rises, reducing cooling efficiency), the thermal stability of the oil under high temperatures is severely tested. This is why some oils become thinner at high temperatures, potentially leading to oil burning issues.
