There are a few schools of thought when it comes to what the oil temperature should be in a car. Some people believe that the ideal oil temperature is between 195-220 degrees Fahrenheit, while others believe that it should be closer to 212 degrees Fahrenheit. Ultimately, it is up to the individual to decide what they believe is best for their car. However, it is important to keep in mind that if the oil temperature gets too high, it can start to break down and degrade, which can lead to engine problems.
