As I mentioned some time ago, I have submitted some particle count (PC) tests to Blackstone Labs. So far I have had PC tests done on oil run with two different filters: Mobil 1 EP and Hyundai OEM.
Both runs were done with Valvoline SynPower 5W-30 (SM). The same air filter was in place for both.
A FilterMag was used in both cases as well. Maybe I should have tested without it, but when I submitted the first sample, I forgot I had the FilterMag installed, so I simply kept it in place when I installed the second filter. I figured that if it skewed the results, it would do so the same for each filter.
Maybe it might have been preferable to extend the mileage somewhat. I cut it off where I did because of how the timing worked out; prior to submitting the first sample, I had completed a 1,400-mile road trip. Then, I made plans to repeat the same trip shortly thereafter. I placed a higher value on duplicating the same types of driving than on longer intervals. (As a short-tripper under warranty, I do 3/3,000 OCs anyway.)
I always round to the nearest hundred miles when I do maintenance; I think it's silly to drill down more than that. 50 miles one way or the other is not meaningful to this.
Don't ask me what the significance of the "ISO Code (3)" results are. I've glanced at the explanations myself and still don't get it.
My reaction to the results: I have one more Hyundai oil filter left. Anyone want it?

Next up is a Royal Purple 10-2808. Can't say when, though.
