Working on it. It killed me to pay $15.99 for the Amsoil filter but this is the list of stuff I have now or on the way:
MO-899
MO-041
Fram Ultra XG2
Mobil M1-210A
RP 20-820
Amsoil EA011
Wix 51372
Wix 51372XP
Purolator Boss PLB24651
Purolator Pure One PL24651
Purolator Classic L24651 (Would never use this, but suspect it may be very similar to MO-899, same manufacturer)
And then a couple cheap ones just for fun. Would never use either of these, but the SuperTech isn’t THAT bad actually for $3:
Fram PH2
Supertech ST2
Since these companies are always merging, changing suppliers etc, I’m hoping to have a nice up to date summary we can reference. I’ve found independent efficiency testing on some and will rely on manufacturer data for the rest.
