According to Chris Jensen, Goodson Tech Services Representative, “After running a race, you should run a flow test, but this can be expensive and take time. Cutting open the used oil filter with the Oil Filter Inspection Tool is the next best thing.”

Jensen explained that most oil filters will trap anything larger than 24 to 30 microns, although some trap particles as small as 1 micron. When you inspect the oil filter, you can actually see what is getting trapped. This can be anything from silicone sealants to broken mechanical parts to worm materials and more. Metal shavings can point you toward mechanical problem that could cause total engine failure.


To be very technical, a sample of the contaminants can be placed on a microscope slide and examined. Jensen suggested checking out a hobby or toy store for an inexpensive microscope.

The Goodson Oil Filter Inspection Tool is part number FIT-1-G and comes with a single blade installed. Replacement blades are available (FIT-W). For more information, contact Goodson at 1-800-533-8010 or online at
