Oil change time
All the studies/reports I have seen the Wix and MC were neck in neck.
I'm planning on getting a duel filter bypass at some point, then I'm going to be going 20-25k miles. (Again, with positive blackstone reports.) Hopefully before this winter, but in the next year definately!

Based on what I have read Wix normally rates their filters nominally while, Fleetguard, Donaldson and Baldwin are normally rated absolutely.
Personally, next change I might run Rotella Synthetic and the Donaldson ELF7405 (10-15 microns absolute, 60% @ 4 microns) for 7500-10,000...depending on UOA.
