How Often to Change an Engine Oil Filter?

With the exception of electric vehicles, all other cars (including your hybrid) have an oil filter. Regarding routine maintenance, the engine oil and oil filter are items that need to be replaced more often than anything else on the vehicle. Yes, even your tires. There has always been a debate as to how often this is necessary, and there always will be a debate because, well, it depends. A general rule of thumb is 5,000 miles between oil changes but this will vary based on vehicle age, usage, and manufacturer requirements.

What Does an Oil Filter Do?

From complex climate control systems to one-time-use face masks, filters are utilized everywhere and have one purpose: stop things from getting to the other side. These things can be anything from large dust bunnies to particles of a few microns, depending on what is being protected. Because of this, filters are designed similarly by combining multiple layers of paper, fabric, and/or other materials to stop certain particulates from passing through.

In an automobile, the oil filter captures these contaminants and prevents them from circulating through the engine. Without an oil filter, dirt and other particles much smaller than a strand of hair can and will freely travel into the engine assembly and cause damage due to clogs and other debris. If the engine parts can’t move, neither will the vehicle.

Oil filters don’t just manage waste but also maintain oil flow. That being said, filters can only absorb a finite amount of pollutants. Once an oil filter is saturated, its efficacy is lost and, thus, you have an unprotected engine.
