lol okAmsoil 0-20 and Wix XP Filter.
The filter is a big deal.
I see where folks on this thread are using Amsoil filters. I wouldn’t follow that practice.
Comparison of construction and attributes shows the Wix XP to be the best filter available.
Because the Wix XP efficiency of 99% at 35 microns is clearly superior to Amsoil/RP's 98.7% at 20 microns and 99% at 25 microns.
