Yeah I'm guessing three weeks from now I'll get the Blackstone report.At least ISO cleanliness 4406 standards are the proper way to measure particle counts & I think it's neat you're running this filter along with a Fram for comparison. We may not know the 100% true efficiencies of either but we could try to put one together, loosely, based on your PC results between each filter for your use case. Has it been 3 weeks yet....
Good Morning Dezlpwer,
what a terrible design, in my opinion. 
That's why you have to do the "clear flood mode" after oil changes to prime the filter etc.I came across this nonsense when servicing a Subaru Legacy with the upside down filter. Car cooled off for like 15-20 mins before I began and I was surprised that the oil filter was EMPTY when I removed it, even with a nice Orange Silicon anti-drainback valve on a quality filter.
The engine sounded TERRIBLE when I fired it back up after the oil change. No way I would EVER own one of these Turds.
P.s. looking forward to the oil filter comparison.
Floor the gas pedal while cranking and engine will crank but not start. Do this till oil light goes out. I agree, ridiculous.
No it's says you are supposed to run a 0W-20 but you can run a 5W-30 in a "pinch".
Thanks. I’m interested in the Forester and was just curious what they allowed. I’m assuming this would be similar to the crosstrek.
Yes pretty much all newer engines these days run thin 0W-20 or similar oil. I run the thicker 0W-30 oil because the Subaru direct injection engines are oil diluters. I have a number of threads on here of every oil analysis done with each oil change since new.
I wonder how an A3/B4 would behave in these.
Not sure but the Mobil 1 ESP 0W-30 I've been running is fantastic, as others on here have also found, and it is an ACEA C3.
