Inlet holes slightly smaller on the PG, tapping plates are noticeably different between the two. PG slightly taller over EG. I would say X4612 is more comparable to a Fram 6607 as the PG to a Fram 7317.
At Y.T. enter MidwestF150 where you'll find videos of oil analyses ( U.O.A. , V.O.A. ) , oil filter openings ( new + used ) and other things of interest . Many are new videos of R&P , P.U.P. , MicroGard oil filters , HONDA oil filter , Purolator , Wix (?) , etc.. There's also emails with VALVOLINE about Restore + Protect .
