The car is difficult to start in cold weather. Check the lubricating oil[汽车修理知识]

★Experts explain

Cold weather engine oil is thick and difficult to start

Under normal circumstances, engine oil becomes relatively viscous when it is cold, so that it becomes resistance to engine operation and causes difficulty in starting. At this time, the wear and tear of the engine has also increased exponentially than during normal operation.

In this case, the car owner should first change to a lower viscosity oil. Of course, if the engine oil is used for too long, the color becomes black, and the adhesion becomes poor, it must be replaced in time.

The vehicle can’t start or it may beOil filterThe problem. It is an oil protection device. If it is used for a long time, it is easy to be blocked by various impurities, carbon deposits, etc., so that the oil cannot flow quickly in the engine, making it difficult to start the vehicle.

★Expert advice

Synthetic oil is more suitable for winter

There are generally two types of motor oils currently on the market: fully synthetic oils and mineral oils. Experts suggest that synthetic oil is best used in winter, because its viscosity change is less affected by temperature, and it can flow smoothly in a low temperature environment, and it can also maintain a proper viscosity in a high temperature environment to reduce engine wear.

In addition, under the continuous high temperature operation of the engine, synthetic oil is not easy to oxidize and decompose, and has a longer use time. Generally, a car that uses mineral oil must change the oil when driving 5000 kilometers, and the oil change mileage for synthetic oil can be extended to 8000-10000 kilometers.

★Expert reminder

Do not mix different brands of engine oil

According to the vehicle manual, select the engine oil of the corresponding quality level or high level.

It is best not to mix two different brands of engine oil. Because different brands of oil products may use different additives, mixed use may cause oil deterioration.

Filling or replenishing the oil should be appropriate, preferably between the maximum and minimum marks on the oil scale.Too much oil will increase the engineCrankshaftResistance, increase fuel consumption, and may be damaged in severe casesThree-way catalytic converter.
