From what everyone is saying or reading, one can only go wrong w/ a Fram filter.
The Mobil filter has one of the highest eff ratings on 1st pass & gets stuff down to 10Microns. Thats why I went w/ M1 available @ Autozone.
Most well made filters (wix etc filter only down to 25microns)
The only way to go lower than 10m's is to use a by-pass filter.
Remember:

So for us NON-by-pass users, changing the oil on a regular basis is critical & the only way to obtain long life.
