Frequently Asked Questions
What does the micron rating on an oil filter mean?
The micron rating indicates the smallest particle size the filter can capture. Absolute ratings (such as 25 microns absolute) mean the filter stops nearly all particles of that size, while nominal ratings allow some particles slightly larger than the stated size to pass through. In our research, absolute ratings provide better protection for extended drain intervals and severe driving conditions, while nominal ratings work adequately for standard 5,000 to 7,000-mile service intervals.
Can I use an aftermarket oil filter instead of the OEM filter recommended by my vehicle manufacturer?
Yes, as long as the aftermarket filter meets the same API performance standards and has the correct thread size and fitment for your engine. In our evaluation, we found that quality aftermarket filters like Bosch, Mobil 1, and ACDelco perform equivalently to OEM filters when specifications match. However, always verify the filter application cross-reference before purchase to ensure bypass valve pressure and housing design align with your engine’s requirements.
How often should I replace my oil filter?
Most manufacturers recommend replacing the oil filter every time you change the oil, typically every 5,000 to 10,000 miles depending on oil type and driving conditions. In our research of published manufacturer guidelines, conventional oil typically requires filter changes every 5,000 to 7,000 miles, while synthetic oil can extend intervals to 10,000 miles or more if your engine and filter are rated for extended service. Severe driving conditions like towing, frequent idling, or dusty environments may require more frequent changes.
What is an anti-drain-back valve and why is it important?
An anti-drain-back valve is a one-way valve in the filter that prevents oil from draining back into the engine sump when the engine is off. In our evaluation of filter designs, this valve is critical because it ensures oil pressure is immediately available upon engine startup, reducing dry-start wear on engine bearings and valve trains. Most quality filters include this feature, though the valve pressure setting varies by manufacturer and engine application.
Should I switch to a synthetic oil filter if I use synthetic motor oil?
Not necessarily. Based on our research of manufacturer specifications, the oil type and filter rating are independent considerations. A quality filter with appropriate micron rating and bypass valve pressure works effectively with either conventional or synthetic oil. However, if you extend service intervals with synthetic oil beyond 7,000 miles, choosing a filter with absolute rather than nominal micron rating provides better protection against contaminant accumulation over the longer interval.
