How long does it take for the car to warm up in cold weather?

It's very cold. Under normal circumstances, the vehicle can be started by heating for one minute or waiting for the tachometer to return to normal. After standing still for a long time, the engine oil will flow back to the oil pan at the bottom of the engine. When the vehicle is not used for a long time (such as overnight) and the engine is started, the upper part of the engine is in an oil-free and lubrication-free state.

But in this case, it only takes about 30 seconds to ignite the engine, and the oil pump can transport the oil to the piston, connecting rod, crankshaft and other parts of the engine that need lubrication most through operation. If you don't warm up the car, but start the engine on the road, then don't slam on the accelerator at high speed within three or four kilometers, and you must try to keep driving at low speed.

Extended data:

It should be noted that it is forbidden to step on the accelerator when the car is hot. Some car owners like to step on the accelerator at idle speed, thinking that this will speed up the hot car. In fact, this is more harmful to the car, which will lead to the rapid wear of the engine and seriously damage the engine parts. Don't slam on the accelerator when driving in the same place. The correct way is to drive slowly at low speed.

Based on all the factors mentioned above, it is really unnecessary to warm up the car at idle speed for too long, because the effect is limited, mainly to protect the engine. If it is too long, it will waste gasoline and time, and it will also emit a lot of exhaust gas to pollute the air. If the warm-up time is too long, the engine will also produce carbon deposit due to incomplete combustion of gasoline at idle speed, which will do more harm to the engine.
