Mg Ruiteng maintenance project, how much is Ruiteng maintenance?

MG Ruiteng needs a major maintenance every 50,000 kilometers, including: three filters, cleaning the fuel injection head, air intake, replacing brake oil, steering oil, transmission oil, checking the coolant and replacing the spark plug. The total cost of materials and working hours is 4,404 yuan, and it is necessary to clean the three-way catalyst and throttle when it is 60,000 kilometers. Major maintenance is based on minor maintenance. In addition to oil and oil filter, air filter, gasoline filter and spark plug have been added to the replaced skin care products. These three filter elements can filter dust in the air and impurities in gasoline respectively. The normal operation of the engine is based on the rational use of various skin care products. If the oil filter is not replaced in time after reaching its service life, it will have a bad influence on the engine performance. Three filters refer to air filters, oil filters and gasoline filters. Filters are used to filter out impurities. The three filters can filter dust in the air, sludge in engine oil, carbon deposit and impurities in gasoline respectively. In addition, after long-distance driving, it is necessary to replace key components such as brake fluid, antifreeze, transmission oil and timing belt.
