1. The basic meanings are different:
Minor maintenance refers to items of routine maintenance carried out at the time or mileage specified by the manufacturer to ensure vehicle performance after the car has been driven for a period of time. certain distance. Mainly includes changing the engine oil and oil filter.
Maintenance refers to the routine maintenance of replacing the engine oil and oil filter element, air filter element and fuel filter element at the time or mileage specified by the manufacturer.
2. Different Intervals:
Minor Maintenance Interval: The duration of minor maintenance depends on the actual life or mileage of the oil and oil filter used.
Major maintenance interval: Major maintenance is based on the existence of minor maintenances, and both types of maintenance are carried outkilled alternately. Intervals vary by car brand and specific recommendations are based on manufacturer recommendations.
Car maintenance precautions:
1. Choose the appropriate engine oil:
Please choose the appropriate grade according to the manufacturer's standards. Engine oil.
2. Replace the “three filters” regularly:
The “three filters” refer to the air filter, oil filter, and fuel filter. Their function is to eliminate impurities in the air. , oil and fuel. After a period of use, various filters will become clogged to varying degrees, which will affect the normal use of the vehicle. Car owners are requested to pay attention to cleaning and replacement.
3. Keep the crankcase well ventilated:
The vehicle's PCV valve can help with engine ventilation, but pollutants in the blown air are released.will pose around the PCV valve, which may be the valve is clogged. This will cause polluted gases to flow back into the air filter, leading to increased fuel consumption, increased engine wear and even engine damage. Therefore, special attention should be paid to cleaning the dirt around the PCV valve.
4. Clean the fuel system regularly:
When fuel is supplied to the combustion chamber through the oil line, it will inevitably form colloid and carbon deposits, which will form in the passages and injectors of fuel oil. It is deposited in the oil burner, combustion chamber, etc. These colloids and carbon deposits will destroy fuel flow, alter the original air-fuel ratio, and cause poor fuel atomization, which will eventually manifest itself as engine shaking, knocking, unstable idling, poor acceleration.ation and other defects. Regular cleaning of the fuel system can keep the engine running smoothly.
5. Maintain the water tank regularly:
Rust and scale in the engine water tank are relatively common problems. Rust and scale will restrict the flow of coolant in the cooling system, reduce heat dissipation, cause engine overheating, and even damage the engine. Regularly cleaning the water tank and removing rust and scale will not only ensure normal operation of the engine, but also extend the life of the engine and water tank.
Routine major vehicle maintenance should be performed every 3 to 5 kilometers. Minor maintenance is determined based on the engine oil used. Different engine oil maintenance intervals are different. For example, my car usesGT engine oil. I use PAO Category 4 base oil, and minor maintenance involves replacing it every 15,000 kilometers, which is three times longer than the semi-synthetic motor oil I used before, and the decay period is also longer than It's long, before, I didn't feel that the car was dull after driving 2,000 or 3,000 kilometers. Now after driving 10,000 kilometers, the power of the car is very good and it is very comfortable to drive. ∞
