Yes, it appears that Filtech, at least in your engine, is a very good combo. Makes you wonder why Fram is/was the alternative OEM
Blackstone did my PC ..and if you noticed ..they've got some incorrect number on mine too. I've got nothing that meets "17". I've got 18 for my >2
If I went from bottom to top (which can't be how they do it) my numbers would be (if I have read the chart correctly).
18/16/15/13/11/7 ..there's no 17 in my sample at all
I'll assume that they were off by one in the 16/15 part of it.
Somehow, I think the fine doctor's PC is off by a factor of 10.
Either that ..or something is very "unright" mechanically and a very poor filter. I tend to lean toward improper calc by the lab.
PC should be PC ..however Dr. Haas's lab may not subscribe to industry standards for their test. They appear to have checked the entire liter of oil. I've always thought that this was "per 100ml sample" ..but I've seen some labs that use 50ml sample sizes for optical PC.
Someone has probably already gone over this a good bit back, but I probably didn't pay attention since most of us use Blackstone ..so we're mostly on the same page.
