I have a new Subaru, which puts me in a slight predicament oil filter wise because Subaru dropped their OE oil filter supplier Tokyo Roki, which made a high quality filter, and gave the work to Honeywell Canada, which of course makes FRAM. The new Honeywell Subaru filters have been cut open by me and other enthusiasts and they are indeed classic FRAM pieces, replete with cardboard end caps.
So comes my predicament. The OE spec for bypass pressure is/was 23.2 psi, this has been quoted from the factory service manual. I can findno after market filter that offers this bypass rating except a Purolator L14460 or PL14460 however specified application for these filters stops at 2006 model year. Other Purolator filters are set for 14 - 18psi bypass.
I have a Wix 51365 on now that is 11psi bypass.
So I guess my question is does using a filter with a significantly lower bypass psi rating than the OE spec present any problems or risks?
I use 5W30 conventional oil and do not do extended drain intervals. I change oil and filter every 3750 on this vehicle.
I don't want to use the OEM filter now made by FRAM's maker, but if sticking to OE bypass psi spec is important then I guess I'll have to.
