| | Oil Filter question
I use a PF48 filter for the GXP I still have a case of PF46/PF44 and was wondering if I can use these instead. Are the threads the same? If it will work, I'd rather use up what I have instead of buying a filter at a time.
I only use AC Delco filters so I don't plan on switching just need to know if the old filters will work.
