What does 1A1B maintenance mean?

1A1B maintenance means one A maintenance and one B maintenance, where A maintenance represents minor maintenance, and B maintenance represents major maintenance. The items included in these two types of maintenance are as follows: Minor maintenance includes: Minor maintenance refers to the routine maintenance items performed at the manufacturer's specified time or mileage to ensure vehicle performance after the car has traveled a certain distance. It mainly includes replacing the engine oil and oil filter, air filter, and cabin air filter. Major maintenance includes: After the vehicle has been used for a certain number of years and kilometers, in addition to the items of minor maintenance, it is also necessary to inspect and replace the vehicle's fuel filter, coolant, transmission fluid, brake fluid, and power steering fluid. At the same time, it is also necessary to check the vehicle's tires, brake pads, belts, and other components.
When I first started maintaining my own car, I didn't understand what 1A1B maintenance meant either. Later, a mechanic explained that it represents two maintenance levels: 1A is a minor service, basically just changing the oil and filters, checking brake fluid, coolant, etc., suitable for every six months or 5,000 kilometers; 1B is a major service, which adds tire and wheel inspections, engine deep cleaning, spark plug checks, etc., typically done annually or every 10,000 kilometers. This classification helps car owners save time and money by preventing issues before they lead to breakdowns. Since buying the car, I've stuck to the maintenance schedule, and the car has remained in good condition with low fuel consumption, especially giving me peace of mind on long trips. Remember, don't delay maintenance dates to avoid unexpected failures. Additionally, different weather seasons, like winter, require extra attention to prevent freezing and starting issues.
