What does AB maintenance mean?
2 Answers
AB maintenance refers to the service codes for car maintenance, where A maintenance is a minor service and B maintenance is a major service. Below is an introduction to the related content: 1. Promotion: Ultra-low fuel consumption, ultra-low interest rates, a key promotion under the National Brand Plan. 2. A maintenance: A maintenance, commonly referred to as a minor service, typically involves basic maintenance tasks performed at the manufacturer's recommended time or mileage to ensure vehicle performance, mainly including oil and oil filter replacement. 3. Oil function: Engine oil is the lubricant for the engine, providing lubrication, cooling, rust prevention, and reducing wear. 4. Oil filter: The oil filter, short for oil filter, removes harmful impurities from the oil in the oil pan, extending the oil's service life, with the two complementing each other.
Last time a friend asked me what AB maintenance is, I told him it's like us getting a physical check-up. The A maintenance is simpler, mainly changing the engine oil and oil filter, plus checking basic items like tire pressure, lights, and brake pads. It usually takes about half an hour, just like a routine check-up. The B maintenance is more complicated, requiring replacement of the air filter and cabin air filter, testing of brake fluid and coolant, and even tightening every screw on the chassis. You won't leave the workshop in less than two hours. I usually follow the car manual's recommendations: get an A maintenance every 5,000 kilometers and a B maintenance every 20,000 kilometers. Doing this makes the engine sound much smoother.
