Why regular engine oil replacement

Metal friction will occur during the car's travel, resulting in "metal powder." There will also be waste accumulations from the burning of fuel. These small particles will be deposited in the lubricant. Therefore, we need to replace the lubrication periodically to keep the engine clean.

Changing the oil cycle When buying a car, car manufacturers will attach a car maintenance manual with the car. The manual lists the oil change intervals or the oil change intervals. Most cars are between 5000-10000 km. In general, the required oil change mileage should be changed. For some high-grade vehicles, oil change prompts will occur when the oil mileage is reached.

In actual driving, road conditions, vehicle conditions, and oil quality all affect the oil change intervals. If you are driving in urban areas for a long time, frequent car start-ups will aggravate engine wear and accelerate oil pollution, so you must shorten the oil change intervals. The owner can regularly check the oil condition of the car and use a dipstick to dip a little oil on his finger. If the oil is black, very thin, and contains gravel, the oil at this time is deteriorating and he must be replaced immediately.

The function of replacing the oil and replacing the three filter filter is to filter various impurities in the oil to prevent the impurities from causing wear to the engine. If the filter is not replaced for a long time, the filter will be partly blocked due to dirt, and the contaminants will flow directly into the engine. Machine wear is aggravated; if only the oil is replaced without replacing the machine filter, the contaminated engine oil remaining in the old filter will re-enter the oil circulation. Therefore, the expert emphasizes that the machine filter should be replaced every time the oil is changed.

In addition to the regular replacement of the filter, the fuel filter (steam filter) and the air filter (air filter) must be replaced on a regular basis. The general replacement standard is to change the steam filter every 20,000 km, and every 10,000 km. Replace air filter.

The Importance of Oil Change Engine oil is as important to the engine as blood is to the heart. Oil contains a variety of additives, can effectively protect the engine's important moving parts, to ensure the normal operation of the engine.

Lubrication: The main function of oil is lubrication, which forms an oil film on the surface of the metal parts of the engine and reduces wear on the metal surface.

Cleaning: Decompose the sludge and deposits generated during the use of the engine and keep the interior of the engine clean.

Anti-rust: Neutralize the acidified substances generated during the engine's use and form a rust-proof anti-corrosion layer to prevent rust and corrosion of metal parts due to oxidation.

Sealing: seal the gap between the piston and the cylinder, so that the fuel burns fully and improves the fuel efficiency.

Cooling: Disperses the high temperatures generated by engine wear and protects the engine components.

During the action of lubricating oil, additives are gradually consumed, and the pollutants produced by combustion are mixed with engine oil to produce sludge and sediment. Over time, these dirt will not only accelerate the engine wear, but also cause engine corrosion and poor heat dissipation. as a result of. Therefore, timely replacement of engine oil is the best care for the engine.
