bbhero: Great post. Quick question on your stats above regarding the 99.6 at 15 microns line.My scoring system here...
99% at 46 and 50% at 22 = no bueno.
Substandard in my opinion. Hastings filter is the same as this Boss 14612.
95% at 20 microns and 50% at 6 microns... Acceptable/ good performance. Old school Wix and Napa Gold filters.... And Fram EG too
99% at 20 microns and 74% at 10 microns = Very good performance. Current Fram Ultra.
99.6% at 15 microns and 80 % at 5 microns = Exceptional performance.... OG Fram Ultra...
Fram's website says the Fram Ultra Synthetic 20,000 mile oil filter is: 99+ efficiency > 20 microns (assuming that is your line #2 above).
FRAM Ultra Synthetic® Oil Filter | 20,000 Miles of Protection | FRAM
Want the best performance from your new engine or the best protection for your older vehicle? There’s no better choice than ULTRA SYNTHETIC® oil filters.

I would like to buy the "OG Fram Ultra..." filter that you mention in your line # 3 above: 99.6% at 15 microns and 80% at 5 microns.
Can you supply more detail on that filter name or an Amazon or other link where it could be purchased?
Thanks,
Bill
