How many degrees below zero will the car fail to catch fire?

At MINUS 35 degrees, the car can't start, because it is difficult to cold start the car when the temperature is between-10℃ and-15℃. When the temperature drops below -40℃, it cannot be started without preheating. In winter, with the decrease of temperature, the viscosity of engine oil will increase, making it difficult for engine oil to flow, thus increasing engine resistance.

Potential security risks

It should be noted that in the case of low temperature in winter, if you want to start the car on the road, it is best to heat the car for a few minutes first. The reason why the car is hot is mainly because of the temperature. After a night of low temperature in the morning, the engine oil will be in a very viscous state, and the fluidity of lubricating fluid will be poor.
