Inappropriate operations during the vehicle running-in period

Do you know what a break-in period is and why it's so important for trucks? Today we will talk about the driving taboos during the break-in period. 

First of all, let's introduce what the break-in period is, so you know why it is so important for trucks.

Before the truck is assembled, each running part is processed separately, and there are geometrical deviations in the processing of the parts, so after assembly, some running parts will be in localized direct contact, and it is difficult for the lubricant to enter the friction surface, resulting in early wear.

During the running-in period, the direct contact parts are gradually worn down, and this period is known as the running-in period. The running-in mileage for a new vehicle is typically between 1000 kilometers to 3000 kilometers.

The running-in period has a significant impact on the lifespan and fuel consumption of vehicles because the wear during this period can cause surface scratches and scars on the parts. These rough scars increase frictional resistance and can also accommodate metal debris, sludge, and other particulate matter, which further exacerbate wear during operation. Ultimately, this can lead to malfunctions, so the quality of the running-in period determines the overall lifespan of the vehicle.

Therefore it is best not to do the following behaviors during the break-in period.

Hard braking is a bad driving habit, especially for the engine, braking system, and chassis of a new vehicle. While driving, proactive driving should be practiced to minimize the impact damage to the engine.

Emergency braking not only impacts the braking system during the break-in period but also increases the impact load on the chassis and engine. It's best to avoid emergency braking within the first 300 kilometers of driving. (However, safety comes first, and if necessary, brake when needed.)

If a new car is run with a full load during the break-in period, it will cause damage to the machine parts.

Therefore, within 1000 kilometers of the initial driving, the general load should not exceed 75%-80% of the rated load.

During the running-in period of a new vehicle, there should be a maximum speed limit for each gear, and it is strictly prohibited to exceed 3/4 of the maximum speed for each gear.

The initial oil used in vehicles is a special lubricant for the running-in period, requiring low viscosity, good heat dissipation, superior cleaning and antioxidant properties. Some manufacturers even add abrasives beneficial for the running-in process. Therefore, during the running-in period, the oil should only be changed according to the manufacturer's specified time and should not be replaced prematurely.

New vehicles do not need to idle to warm up before starting. Idling to warm up while stationary can seriously damage the turbocharger, even in winter.

Many drivers and experienced drivers are concerned about changes in fuel consumption during the running-in period. Basically, the fuel consumption of a new vehicle decreases within the first 60,000 kilometers. The difference in fuel consumption before and after can be within 1 to 2 liters per hundred kilometers. If the trailer is also new, this number will be even greater.

After surpassing 60,000 kilometers, there is still room for further decrease in fuel consumption, although it may not be as pronounced. Depending on the driver's previous driving habits, by the time the mileage reaches 80,000 to 100,000 kilometers, the fuel consumption generally no longer decreases due to the increase in vehicle mileage.

If a car undergoes proper procedures during the break-in period, avoiding what shouldn't be done, it not only affects fuel consumption but also greatly impacts the lifespan and smooth operation of all vehicle components.
