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?

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.

There have been some threads posted on here as well as the other forums discussing 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.

Take note- that this DOES NOT APPLY to the older 3.6's in the 2008 and 2007's- as these used the LY7 3.6.
Make sure you have the LLT


#PIP4889: Engine Break In Oil Filter Number PF48 From New Delivery - Not The Same As The Service Number PF63 In Owners Manual - (Mar 8, 2011)

Subject: Engine Break In Oil Filter number PF48 From New Delivery - Not The Same As The Service number PF63 In Owners Manual

Models: 2011 Buick LaCrosse
2011 Buick Enclave
2011 Chevrolet Traverse, Equinox
2011 GMC Acadia, Terrain
Only with engine RPO Codes LF1, LFW, and LLT 3.6L

--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Some customers may comment that the oil filter # the engine came from the factory with is not the same # required for service per the owners manual and gm parts catalog. Engine was delivered with AC Delco PF48 and Service Oil Filter is AC Delco PF63

Recommendation/Instructions:
The PF63 filter has the same high quality attributes as the PF48 with but is 22mm longer which will provide an additional 22 mm of media filtration material. There will also be additional filtration protection during high mileage oil change intervals. The PF63 filter is a NEW release for the 2011 model year. These 2011 engines will be built with a break in oil filter of PF48 with service replacement being PF63.

The PF63 filter can be used on all M/Y vehicles with RPO codes LLT, LF1 and LFW engines if PF48 is the service filter.
