Can You Drive with Low Engine Temperature?

[John]

It is not advisable to drive when the engine temperature is low. Here are the specific details: 1. After a car has been parked for an extended period, the engine oil inside has mostly drained back into the oil pan, and the oil film on the surfaces of the friction pairs in the engine is largely destroyed. At the moment of startup, friction generates relative motion, but the oil pump has not yet delivered oil to the friction surfaces in time. This results in dry friction on the surfaces of the friction pairs, causing the greatest wear on the engine during the cold start phase. 2. Since low engine temperature increases engine wear, there should be a warm-up process after a cold start. After starting the vehicle, allow the engine to idle at a higher speed automatically. Wait until the idle speed drops to the normal range (around 800 rpm) before driving. Until the engine temperature reaches the normal range, avoid exceeding 2,500 rpm, keep the engine load under 30%, and refrain from aggressive driving behaviors such as rapid acceleration or hard braking. 3. Only after the engine temperature reaches the normal range (80°C-90°C) should you drive normally.
