Is the oil filter cheap?

Frequency of oil filter replacement

The function of the filter is to remove dust, impurities, oil, fuel and coolant from the air, keeping these impurities away from the engine and thus protecting the engine system. High-quality and high-efficiency filters can capture and filter out more impurities than low-efficiency and low-quality filters. If the ash holding capacity of the two filters is the same, it can be seen that the replacement frequency of high-quality and high-efficiency filters will be higher. Most of the lower filters sold on the market have short circuits in the filter elements (impurities directly enter the engine system without filtration). The cause of the short circuit is that the filter paper is perforated, the head and tail of the filter paper are not bonded or not firmly bonded, and the filter paper is not firmly bonded to the terminal cover. If you use such a filter, you won't need to replace it for a long time, not even for a lifetime. Because it has no filtering function at all. So, the above view is wrong.

Damage to the lower filter

You may or may not immediately notice the impact of inefficient and poor-quality filters on your engine. The engine seems to be running normally, but harmful impurities may have entered your engine system and begun to cause corrosion, rusting and wear of engine parts. These damages are hidden and will erupt when they accumulate to a certain extent. So, although you can't see any signs now, it doesn't mean the problem doesn't exist. Like a hidden time bomb. Once the problem is discovered, it might be too late and you will have to spend a lot of money repairing the engine. Therefore, consistently using high-quality and reliable filters can protect your engine to the greatest extent.

High-quality filters can reduce the frequency of replacement

The quality of a filter is measured not only by its lifespan but also by its filtration efficiency. High-quality filters should have high filtration efficiency and a long service life. Therefore, when designing filters, genuine filter manufacturers should fully consider all performance indexes of the filters. Many of the filters sold on the market are simple copies and imitations of the original parts, and most of their performances fail to meet the requirements of technical engineering standards and engine manufacturer specifications. After dissection, analysis and testing of other filters on the market, the results were astonishing: severe leakage and short circuit at the connection between the head and tail of the internal filter element or the connection between the filter paper and the end cover. If you purchase and use a filter without filtering function, even if it is replaced frequently, it will not effectively protect your engine.
