The replacement of the oil filter is very important in car maintenance. It acts as a filter oil to prevent impurities from entering the engine and protecting the engine. Therefore, it is especially important to choose a good oil filter, so how to identify the quality of the car oil filter?
1: look at the font definition. The surface of the high-quality oil filter is clear and neat, with beautiful workmanship and no burrs. Inferior fonts are vague and the surface is rough. The paint is not strong enough, and the nails are easy to fall off.
2: Look at the package verification security code. The high-quality oil filter has a complete package, the label is marked with the brand, anti-counterfeiting code, etc., verify the QR code on the package, verify whether it is genuine.
3: Look at the filter paper. We all know that the role of the oil filter is to filter impurities, dust, etc. in the oil, so the quality of the filter paper is directly related to product performance. Generally, the gap between the hole and the hole of the filter paper is small, the filter can be well filtered, the workmanship is relatively neat, and it is made of professional filter paper. The inferior filter paper is generally rough, not a professional filter paper, made of cheap cotton pulp paper, and the filtering effect is poor.
4: Look at the sealing ring: a good sealing ring can guarantee 100% oil leakage, made of special rubber, with grease or Vaseline protection at the factory, the sealing ring has good texture, no burrs, and the work is complete. Inferior quality looks rough, burrs, scratches, etc., and oil leakage is likely to occur during use.
5: See if there is a bypass valve. When the oil filter is clogged, if there is no bypass valve, the oil will not enter the engine and will not be lubricated, which will increase engine wear. High-quality oil filters generally have bypass valves, which are generally inferior and cheap. Before buying, ask if the merchant has a bypass valve.
Finally, it is recommended that you use some brand-name oil filters. Protect the engine, starting with the oil filter!
