In car maintenance, we often focus on the engine oil, but easily overlook another key component that is closely related to it - the oil filter. If oil is the "blood" of the engine, then the oil filter is the "kidney" of the engine. Its function is to filter impurities in the oil, keep it clean, and ensure the healthy operation of the engine. Why is it equally important as engine oil? During the operation of the engine, the friction of metal components produces tiny metal debris, while combustion also produces carbon deposits and gum. These impurities will mix into the engine oil and circulate to various corners of the engine as the oil circulates. If these 'junk in the blood' are not filtered out, they will: Accelerated wear: Grind precise internal engine components such as crankshafts, camshafts, and cylinder walls like sandpaper. Blocked oil passage: Severe accumulation of impurities may block the critical passage for transporting oil, resulting in local lubrication failure of the engine and causing fatal damage such as cylinder pulling and tile burning. Causing oil performance failure: Even if the oil itself has not reached the replacement cycle, heavily contaminated oil has lost its ability to…

In modern cities, we are well aware of the importance of wearing masks for health. The same goes for the engine of a car, and the "mask" that provides protection for it is the air filter. This seemingly simple paper filter element shoulders the responsibility of inhaling clean air for the engine, directly affecting the engine's power, fuel consumption, and lifespan. Why do we need to wear masks? The working principle of an engine is to inhale air and mix it with fuel before combustion. If unfiltered air directly enters the engine, impurities such as dust, pollen, and sand particles contained in it will become "abrasives", accelerating the wear of precision components such as cylinder walls and piston rings. Long term use of dirty air filters can lead to: Decreased power and increased fuel consumption: clogged filter leads to poor air intake, making it difficult for the engine to breathe and resulting in insufficient oil and gas mixing, leading to reduced power. In order to maintain power, the ECU will inject more fuel. Abnormal wear: Fine particulate matter enters the cylinder, like feeding sand to the engine, causing early wear. Poor combustion: Dirty air filters can break the ideal air-fuel…

The wiper may be one of the most inconspicuous accessories on a car, lying quietly under the windshield. However, once encountering rainy or snowy weather, its value is instantly highlighted. A good wiper can provide you with a clear and bright view, which is the first and most important guarantee for driving safety on rainy days. It's not just about wiping the rain The responsibility of modern wipers has long gone beyond simply wiping the rain: Clearing rainwater: Quickly scrape off rainwater to ensure clear visibility ahead. Cleaning dirt: Mud, bird droppings, insect glue, and other debris splashed during vehicle operation need to be cleaned with windshield wipers and windshield washer fluid. Dealing with snow and frost: In cold regions, specialized snow or ice scrapers can more effectively remove snow and ice. Aging symptoms and replacement signals Wipers are rubber parts that, when exposed to sunlight and rain for a long time, will inevitably age. When the following situations occur, it means that replacement is needed: Unclean wiping: leaving water marks and striped water film, affecting vision. Abnormal noise shaking: making a piercing "croak" sound or violently jumping when scraping. Rubber strip hardening/cracking: When touching the rain scraped rubber strip…
