Metal Cased Oil Filter - The Metal Guardian Protecting Your Engine

How Metal Oil Filters Work

Construction: They feature a metal cylinder housing or cartridge lined with pleated surgical-grade stainless steel micronic mesh.
Filtration: Designed to catch debris, usually rated around 20 microns, while allowing higher volume oil flow than tightly packed paper.
Maintenance: Instead of throwing them away during an oil change, you wash, clean, and reinstall them.

Pros and Cons

Pros: Eco-friendly (less waste), long-term cost savings if you keep the vehicle a long time, and higher structural resistance under high oil pressure.

Cons: Higher initial upfront cost. Some independent testing indicates that wire-mesh metal filters can have lower overall fine-particle trapping efficiency compared to standard high-efficiency synthetic paper filters.

Differences Between Metal Cased and Paper-Based Oil Filters

In addition to the metal cased type, oil filters also come in a paper-based filter cartridge design, where the primary filtration medium is filter paper. 

The two types have their own distinct characteristics, and the choice of which to use typically depends on the specific requirements of the vehicle and the manufacturer's recommendations.

The Importance of Regular Oil Filter Replacement

The oil filter replacement interval is determined by factors such as the vehicle's usage conditions, driving environment, and oil quality. Failing to replace the oil filter on time can lead to deterioration of the filtration performance, which in turn can impact the engine's performance and service life. Therefore, regularly inspecting and replacing the oil filter is an important step in maintaining the vehicle's optimal operating condition.
