Who determines the vehicle maintenance cycle based on vehicle category and operating conditions?

Vehicle maintenance cycles are determined by transportation companies themselves, taking into account factors such as vehicle category, operating conditions, mileage, road conditions, and service life, to ensure proper vehicle maintenance. According to Article 16 of the 'Regulations on the Technical Management of Road Transport Vehicles,' road transport operators shall determine vehicle maintenance cycles independently based on national standards, vehicle maintenance manuals, user manuals, and other factors including vehicle category, operating conditions, mileage, road conditions, and service life, to ensure proper vehicle maintenance. The maintenance cycle refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle. Different vehicle brands and models have different maintenance cycles, with common cycles being 6 months, 8 months, or 12 months. The replacement cycles for different components are determined either by time or wear conditions.
Having driven for over a decade, I believe maintenance intervals mainly depend on several factors. Manufacturers provide basic recommendations in the manual, such as changing oil every 5,000 kilometers for sedans, but adjustments should be made based on actual driving conditions. My pickup truck, which frequently operates on construction sites, requires maintenance every three months, primarily focusing on the chassis and suspension. As for the family hatchback used for grocery runs, simply following the manual suffices. Mechanics at repair shops can help assess conditions, like checking oil color or brake pad thickness. The key is to consider the vehicle category: maintenance needs for off-road vehicles and sports cars are entirely different. Operating conditions also matter significantly—cars constantly stuck in city traffic accumulate more carbon deposits and thus require more frequent maintenance than those regularly cruising on highways. It's advisable to develop a habit of regular inspections rather than waiting for issues to arise before repairs.
As professionals in auto repair, we all know that vehicle maintenance intervals are determined by multiple factors. Manufacturers provide the basic framework, such as oil change intervals. But for each specific vehicle, our technicians conduct a comprehensive evaluation: different vehicle types have different requirements - for example, electric vehicles focus on battery cooling systems, while diesel trucks need special attention to filters. Then we adjust based on actual vehicle conditions - if brake fluid moisture content exceeds standards, it needs early replacement; abnormal tire wear also calls for shorter inspection intervals. The owner's usage habits are crucial - trucks frequently hauling heavy loads obviously require more frequent maintenance. Finally, we provide a maintenance recommendation sheet that combines vehicle characteristics with current status to develop a customized plan.
As automotive engineers, maintenance cycles are designed during the R&D phase. The basic cycle is determined based on the characteristics of different vehicle models: SUVs have shorter differential inspection intervals than sedans, and hybrid vehicles require regular battery checks. However, during actual implementation, 4S dealerships dynamically adjust based on the current vehicle condition. For example, if diagnostic trouble codes indicate abnormal transmission fluid temperature, maintenance is required even if the scheduled interval hasn't been reached. Or if chassis inspection reveals cracked suspension bushings, they will be replaced in advance. Usage intensity must also be considered - for the same car model, a ride-hailing vehicle covering 300 km daily versus a weekend family car may have double the difference in maintenance frequency. Therefore, the manual provides only reference values, with final decisions made by professional technicians through comprehensive assessment.
