It doesn't look bad, but it only has 500 miles on the oil. You could put new oil in an engine and run it 500 miles with just a screen for an oil filter and probably have a PC that doesn't look too bad. Like I've mentioned in other threads about PC data, to get a real apples-to-apples comparison of in field filter performance using an ISO 4406 particle count, the filters need to ideally be ran on the same engine and basically used in the same conditions for the same OCI. As the miles get put on the oil more debris is generated, and the lower micron size levels should start increasing because filters are less efficient at capturing the smaller stuff, and less efficient filters may also slough off debris with loading dP - a more inefficient filter will show that. This all points back to the reasons to use a high efficiency oil filter for longer OCIs. PS - Yes, the ISO 4406 particle count is the number of particles per mL of oil.
Thanks for testing at 500. I'll patiently wait for your 8500 mile results w/HPL 5w-20.
Thanks. Like I said, it’s been awhile since we discussed particle counts. Didn’t want to jump off the deep end without a refresher from somebody more knowledgeable.
Nice! The next particle count will tell more. Just understand that because it’s a purolator no matter how great it might preform, around here it will be minimized and or overlooked.
Although you’re not going to get an accurate representation of the filter by using the magnets. If you want to get the best data, you’d run almost your full OCI on filter alone & pull sample. Then add magnets and pull another sample 500 miles later. That way you can separate the effect of the magnets vs the filter itself. You may well find that the magnets are more effective on some filters than others… I’d bet the less-efficient filters would end up with more on the magnet, but that’s a WAG at this point.
Well to be honest nothing at the moment. Stocked up on that $25 5w-40 Mobil Euro Walmart glitch.
Plus about x2 Mobil Delvac 15w40 in 5 gallon buckets. Think you've run some HPL right?

It took almost 3 weeks
3 weeks is a very long time, WearCheck only took 2 days from the day it arrived to their lab.
Using the magnets could skew the actual performance of the filter to some degree, especially if a pretty inefficient filter is ran. A high efficiency filter that can capture a good percentage of 5u particles would probably show better performance than an inefficient filter without magnets in the mix.
