What is the Difference Between Minor and Major Maintenance?
1 Answers
Minor maintenance generally refers to the routine maintenance tasks performed at the intervals or mileage specified by the manufacturer to ensure vehicle performance. It mainly includes changing the engine oil and oil filter. Major maintenance, on the other hand, involves changing the engine oil, oil filter, air filter, and fuel filter as part of the routine maintenance schedule set by the manufacturer. Minor maintenance includes the following items: 1. Engine oil: This is the lubricant for engine operation. It lubricates, cleans, cools, seals, and reduces friction in the engine. It plays a crucial role in minimizing wear on engine components and extending their service life. 2. Oil filter: This component filters the engine oil. Engine oil contains certain amounts of gum, impurities, moisture, and additives. During engine operation, metal particles from component friction, airborne impurities, and oil oxidation products are all filtered by the oil filter. If the oil is not filtered before circulating through the system, it can adversely affect engine performance and longevity. Major maintenance includes the following items in addition to changing the engine oil and oil filter: 1. Air filter: The engine inhales a large amount of air during operation. If the air is not filtered, dust in the air can accelerate wear on the piston assembly and cylinder. Larger particles entering between the piston and cylinder can even cause severe "cylinder scoring." The air filter's role is to remove dust and particles from the air, ensuring that clean and sufficient air enters the cylinder. 2. Fuel filter: The fuel filter provides clean fuel to the engine by filtering out moisture and impurities from the gasoline. This optimizes engine performance and offers the best protection for the engine. 3. Typically, during vehicle maintenance, technicians will perform additional inspections based on the vehicle's condition and may include other maintenance tasks, such as inspection and cleaning of engine-related systems, tire alignment checks, and inspection of various fastening components.
