Today's engines have very tight tolerances, multiple oil pressure control systems and high
flow lubrication system requirements. These requirements will vary based on the specific
engine design, so the proper match of oil filter to the engine application is more important
than it has ever been in the past.
The High Feature V-6 engines RPO (LGX, LGY, and LGW) have higher oil pump pressure to accommodate engine cam phasing and high-speed bearing requirements. As a
result, the oil filter performance was improved to meet this higher oil pressure output.
The new UPF63R oil filter has a thicker outer shell to provide higher burst pressure
resistance during cold temperature conditions and greater fatigue strength. Failing to use
this filter could result in external oil leaks due to gasket blowout or wrench flute cracks.
• UPF63R Oil Filters are specified on LGX engines and must be replaced with the same
filter (NOT PF63) when required.
• PF63 oil filters are specified on other HFV6 engines and can be replaced with the
same filter.
Any time an oil filter is changed on one of the above vehicles, it is recommended to use
the new and improved filter.

Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
