How many kilometers does a new car's CVT transmission need for the break-in period?

New car CVT transmissions require a break-in period of 5,000 kilometers. During the automatic break-in period for CVT transmissions, it is necessary to accelerate slowly and maintain a maximum speed not exceeding 90 kilometers per hour. When starting the engine of a new car, special attention should be paid to warming up. Owners should wait until the coolant temperature gauge needle moves and the idle speed on the tachometer decreases before driving. During the break-in period, engine oil gradually forms a protective film between engine components, reducing dry friction and wear on the crankshaft and cylinder walls. It is advisable to avoid driving at full load during the break-in period, as excessive load increases stress on both the engine and transmission, leading to higher engine output power and causing excessive wear on mechanical parts.

What to Do with China 5 Vehicles After the Implementation of China 6?

After the implementation of China 6, China 5 vehicles can still be driven as usual. The China 6 standard will not have any direct impact on China 5 vehicles, but it may accelerate their depreciation. In some cities or regions where the China 6 emission standard is enforced, China 5 vehicles may no longer be eligible for registration, so this should be considered when purchasing a car. The new emission standard primarily targets automakers, requiring that all newly sold vehicles must meet the China 6 standard. This means that upgrades in powertrain technology will be necessary, involving significant manpower, material resources, and financial costs, which will ultimately be passed on to consumers, leading to higher car purchase costs. The term 'China 5' in vehicles refers to the emission level of tailpipe pollutants—the higher the number, the stricter the standard, and the lower the engine emissions.
