What’s in an Oil Filter

There are several main components in an oil filter.

The shell is the solid material that surrounds the actual filter. It keeps your filter safe during the wear and tear on your vehicle and protects it from punctures.

The media is the component that filters the oil. It’s a maze of cellulose, synthetics and micro-fibers that removes harmful debris from your engine oil.

The core of the filter is inside the filter media and constructed from a variety of materials. It helps keep the shape and prevents it from collapsing under extreme pressure.

The base plate is the threaded part of the filter. It also directs the oil flow.

The gasket is the flexible rubber ring that seals the filter to the engine’s oil filter base.

Types of Filters

The quality of the filter depends on the material used to make each part.

In basic filters, the media is of natural wood fibers. These filters do the job but need to be changed frequently.

Middle-grade filters use a blend of fibers that are primarily cellulose with a minimal amount of synthetic fibers. These enhance the media strength and efficiency performance.

Premium filters, such as those from Royal Purple, use microglass filter technology. These advanced filters are designed to extend the life of both vehicle and equipment. In addition to superior filtration media, the other internal and structural components are of higher-quality materials, making for easier installation and removal as they are much less likely to crush in the process. Just as the company’s motor oil lasts a long time, Royal Purple oil filters can extend change intervals up to 12,000 miles.

Vehicles under warranty should follow the vehicle manufacturer’s recommended filter change intervals.
