Which oil filter..

[Soft Cars]

Only true for the gigatic sized PB30001. Other sizes have pretty bad efficiency. There are a few threads in this forum showing specific spec sheets from M+H for smaller size Boss filtets, and the efficiency is way worse than 99% @ 25μ.

In that case, what's the efficiency rating for a PBL10111 ? If you don't mind me asking.

You would have to contact Purolator/M+H and ask for a spec sheet for the PBL10111.

So Purolator for the BOSS shows ISO 4548-12 on PBL30001 as 99% @ 25 microns. But the spec sheet for PBL30001 BOSS show 99% at >46 microns, and 50% @ 22 microns. So seems they are mis-advertising on their website perhaps.
