At what engine temperature can a car start moving?

Car engine temperature needs to be maintained around 90 degrees Celsius, at which point the engine can perform at its peak. The impacts of starting a vehicle with excessively low engine temperature are as follows: Increased fuel consumption: When driving with low engine temperature, it causes certain damage to the engine while also increasing fuel consumption, with noticeably reduced engine performance. Failure to meet emission standards: When external air is cold and engine temperature is low, it also affects the engine's fuel performance. Poor fuel performance makes engine exhaust extremely pungent, causing the vehicle's emissions to fall below normal standards. Damage to oxygen sensors: It can also damage the vehicle's oxygen sensors and even affect the normal operation of other components. Therefore, it's advisable to warm up the car before winter trips and only drive when the engine temperature reaches the standard level.
I've been driving for over 20 years, let me share some experience: Don't rush to drive off immediately after starting the car. Wait until the coolant temperature rises to normal operating temperature before setting off for safety. The so-called normal operating temperature is when the needle on the coolant temperature gauge reaches the middle zone, approximately around 90°C. Why wait? Because when the engine is cold, the lubricating oil hasn't warmed up yet—it's thick and viscous. Starting off immediately creates greater friction and wears down internal engine components. I usually wait two to three minutes—shorter in summer, longer in winter. For example, during northern winters, I'll sit in the car listening to music after starting it, waiting until the temperature gauge moves before driving. This ensures the engine runs smoothly and the car drives effortlessly, protecting it from breakdowns in the long run. Don't try to save that minute or two—over time, it'll increase fuel consumption and degrade performance. Developing the habit of waiting for the coolant temperature saves money and gives peace of mind.
