I’m using the RP 20-500 which is mid sized like and XG10575, FL500 s, or PF63
This filter came off today at 10k … I had planned to run a bit longer, but oil pressure was at 60 psi this am (40 is norm) for the first few miles while the engine warmed. It was 80F outside … and the oil is 0w20.
Put on a PF63E … will go another 2k or so on this OCI.
Somebody asked if these had baseplate PRV … but it’s dome end and looks similar to Wix XP design
