Starting with the 2011's the AC Delco filter recommended is the PF63. Up until then it was the PF48. Yes the 63 is a tad larger to clean the oil better.tqracn said:I was informed by a Buick owner , that the 2011 3.6 oil filter for a Buick Enclave is bigger than the Outlook filter?
Does anyone have any experience with this?
Actually, the larger filter is specified to add an incremental increased oil capacity for the engine. The PF48 and PF63 filter media material are the same... and for owner's who are will to test the contamination capacity, to the point of actuating the filter bypass valve, the difference in filtering capacity doesn't make much difference.Sailfish said:Yes the 63 is a tad larger to clean the oil better.
