1. Whether it is a new car or a classic car, it is necessary to warm up before starting. Because the temperature of the newly started engine is low, the lubricating oil of each part is not in place, and the parts that are in contact with each other will not be fully lubricated immediately, resulting in parts loss. In this case, friends who love environmentally friendly cars will be very entangled, because after starting the engine, the vehicle will start to produce exhaust gas (more than that emitted by normal driving), but the vehicle must be "warmed up". However, if the engine is "warmed up" for a long time, it will not only produce a lot of carbon deposits, but also be detrimental to environmental protection. So I suggest you start the vehicle in about 10 seconds, which is equivalent to the time to fasten your seat belt and tidy up your clothes.

In addition, "hot cars" are also divided into seasons. For example, the temperature is very low in winter, and the oil lubrication is not good enough. At this time, the idle time can be a little longer, generally about 30 seconds, and then continue to warm up by driving at a low speed of 1 ~ 2 kilometers, so as to avoid the negative impact caused by long-term idle.

2. Avoid overloading. During the running-in period of the vehicle, the parts in the engine are still in a state of "collapse". If it is fully loaded all day, it will cause some damage to the parts. It is generally recommended that new cars in the running-in period should not exceed 80% of the rated load.

3. Avoid long-distance driving and high-speed driving. Long-distance driving means that the engine works continuously for a long time, which is a load for the parts that have not been "communicated" well inside the engine, which will directly affect the cooperation between the parts and is not conducive to the long-term use of the engine. .

In addition, it is best to avoid high-speed driving for cars in the running-in period. According to the data, it is best to control the speed of new cars within 40-70 km/h during the running-in period, and it is not allowed to drive at too high a speed. During driving, pay attention to the engine tachometer and speedometer to ensure that the engine speed and speed are not too high. In general, it is recommended to keep the maximum engine speed at 2000-4000 rpm during the running-in period.

4. Use better quality fuel. In fact, whether it is a new car or an old car, they can't use fuel with a label lower than that specified by the manufacturer (the label is usually on the fuel tank cover). This is even more important for new cars that are still running in. If conditions permit, try to use better quality and higher grade fuel. It is best not to add anti-wear additives. Advertisements for such additives are always beautiful, but they don't have much effect in essence. If additives are added, there may be enough mileage and insufficient running-in.

5. Gear shifting needs to be timely, mainly for novices and friends who use manual transmission models. Shifting gears in time is to avoid high-gear and low-speed driving, which is unfavorable to the long-term use of the engine. Don't use a gear for a long time, the gear will shift up and the gear will shift down. You must reach the highest gear speed every time before you can switch.
