How do I know which oil filter to buy?

The main function of engine oil is to help your engine lubricate, absorb carbides and oil stains on parts, help the water tank cool the engine, and play the role of cushioning. The oil filter is for the engine, so it is very important to choose a suitable one. This article mainly introduces the types of oil filters currently on the market. And help you determine which filter is the best quality.

How to know which oil filter to buy?

Oil filter types

Mesh oil filter: It uses copper mesh as the filter material and one or two layers of copper mesh are wrapped on a plastic or metal cylindrical frame with many holes nearby, and its filtering accuracy depends on the number of layers of copper mesh and mesh size. This kind of oil filter has a simple structure, large flow capacity, and convenient cleaning, but has low filtration precision, and is generally used for the oil suction port of hydraulic pumps.

Wire gap oil filter: It is composed of steel wire or aluminum wire tightly wound on the outside of the cylindrical frame, and the impurities mixed in the liquid are filtered out by relying on the tiny gap between the copper wires. Its structure is simple, the flow capacity is large, and the filtration accuracy is higher than that of the mesh oil filter, but it is not easy to clean, and most of them are oil return filters.

Paper oil filter: It is made of plain or corrugated phenolic resin or wood pulp microporous filter paper. The paper core is wound around a frame of perforated tin iron for added strength. In order to increase the filtration area, the paper core is generally made into a folded shape. Its filtration accuracy is high, and it is generally used for fine filtration of oil, but it cannot be cleaned after it is blocked, and the filter element must be replaced frequently. The more common ones are 1r-0716, 1922496, and other filter elements.

Sintered oil filter: It is sintered with metal powder, and uses the micropores between the particles to block the passage of impurities in the oil. The filter element can withstand high pressure, has good corrosion resistance and high filtration precision, and is suitable for high-pressure and high-temperature hydraulic systems that require fine filtration. The necessary means for the normal work of the hydraulic system.

How to justify a good oil filter?

No matter what kind of oil filter you choose, you need to consider the following characteristics first:

1. Model compatibility. Because different models need to be equipped with different filters, if the size is not in compliance, it will cause failure to install or oil leakage. Secondly, different types of vehicles have different requirements for oil cleanliness. The higher the filter density, the purer the oil that can be filtered.
2. High quality. High-quality filter paper can filter impurities very well, and can also ensure the smooth passage of engine oil. Of course, when the filter element is used for a long time and the oil pressure is affected, it must be replaced in time. Then there is the skeleton, which supports the filter paper. The rubber gasket at the connection between the filter element and the engine is also very important. If it cannot withstand high temperatures and age, oil leakage will occur and the engine will be damaged.
3. When choosing a filter element, in addition to looking at the appearance, you should also ask the merchant whether there is a "bypass valve" device in the filter element. The role of the bypass valve is to open a shortcut when the vehicle is cold-started, the viscosity of the oil is relatively high, the fluidity is relatively poor, and it cannot pass through the filter paper well to reach the parts that need lubrication.

In conclusion, choosing the right oil filter is important to maintaining your engine's performance. Consider filter type, model compatibility and quality to ensure optimal filtration and oil flow. Whether you're asking, "How do I know what oil filter to get?" or you're looking for guidance on finding the right oil filter, this article provides valuable insights to help you make an informed decision based on your vehicle's needs.
