As we all know, the engine oil of a vehicle needs to be replaced after traveling about 5,000-10,000 kilometers. At the same time, there is another very important component that also needs to be replaced, that is, the oil filter!
The oil filter is the “kidney” of the car. It is mainly used to filter impurities and pollutants in the oil, such as dust and water that enter through the engine; metal chips produced by cylinder wear; and other substances produced by oil oxidation. Incomplete filtration can easily cause poor engine operation, and even worse, lead to engine overhaul.
So what factors should a high-quality oil filter have?
Excellent filter element processing technology
While the oil filter is filtering oil impurities efficiently, it also needs to withstand the impact of oil flow and cannot be damaged or leaked. Arrow Filter uses high-grade filter paper containing PET fiber, which has better anti-aging and anti-carbonization properties. It ensures that the paper core can efficiently filter oil impurities while also resisting the impact of high-speed oil flow, ensuring that the filter paper will not collapse or break.
High quality bypass valve
Do not underestimate the small parts of the oil filter. If you encounter a low-quality bypass valve, the bypass valve may be normally open, causing unfiltered oil to flow to various parts and damage the engine. It is also possible that after the filter is blocked to a certain extent, it fails to open in time, resulting in untimely lubrication and dry grinding.
High quality check valve
If the bypass valve is an indispensable part in vehicle operation, then the check valve is an indispensable part after the engine is turned off. A high-quality check valve can prevent the oil in the oil filter from flowing back and provide oil to the lubrication system in time when the engine is started again to prevent dry grinding.
Finally, it is important to note that even a high-quality oil filter can cause oil leaks or fall off if it is not installed properly.
