2012 And Newer 6.0L Oil Filters

Recommended Posts

There has been some controversy over what is the correct oil filter for Gen. IV LS engines like the L96 and LC8 6.0L's.  There was a service bulletin issued a few years ago that stressed the importance of using an oil filter with a bypass valve setting of over 15 psi for various GM gasoline engines, including the Gen. V 5.3L and 6.2L.  A subsequent revision to that bulletin dated 07/13/2018 (#17-NA-157) added the 2012 and newer Gen. IV L96 and LC8 to the list of engines requiring an oil filter with a bypass valve of over 15 psi..  The recommended AC Delco oil filter for the Gen. IV's was the PF48 (15 psi bypass), but the bulletin calls for either the PF63 or PF64, both of which have a 22 psi bypass valve.  The PF63 is taller than the PF64, which is the same size as the PF48.  What is funny is that if this bulletin is true, most all of the aftermarket oil filter manufacturers still call for a PF48 equivalent for these engines like the NAPA 7060 or WIX 57060.  It appears that these aftermarket oil filters all have bypass valves less than 15 psi..  I am thinking about using the AC Delco PF63E or UPF63R for these engines.  What are you using?

I purchased  purolator PL22500 . It states on their site that it’s rated 22 psi.

The 57060 has been replaced by the WL 10290 (22 psi)

The 57045 has been replaced by the WL10255 (22 psi) 

New spec went into effect 4/5/2017

Yes, but bulletin 17-NA-157 was revised on July 13, 2018 and one of the changes was that engine RPO's L96 and LC8 were added.  Both NAPA and Wix still list the 7060/57060 as the correct filter for these engines, which appears to be wrong.

L96 uses the PF-48.  It does not use the PF-63 or PF-64 nor does it have a dual stage oil pump.  At no point in the GM parts catalog 2010-2019 L96 does it list the PF-63, only the PF-48.  

 

There is no change to the L96 2010-2019.  The replacement crate engine is the same p/n 19256594, same oil pump 2010-2019 p/n 12710303.  PF-48 is the correct filter.

 

The bulletin is more targeted at the fact that the PF-48 looks like the PF-64 and the PF-63 will screw on, but dual stage oil pump engines (anything that uses a PF-63 or PF-64) CANNOT use the PF-48 as it will cause unfiltered engine oil to circulate.

#17-NA-157: Information on Spin-On Oil Filter Replacement for Gas Engines Designed with New Oil Pump Control Systems - (Jul 13, 2018)

Today's engine has very tight tolerances, two stage oil pumps and high flow lubrication system requirements. The proper match of oil filter to engine application is more important than it has ever been in the past. The use of a replacement oil filter with an internal bypass valve opening pressure specifications of 15 PSI (100 kPa) or less, allows debris to circulate in the engine causing damage to bearings and other tight tolerances areas, which may result in premature engine failure.

The oil pressure was increased to accommodate these tighter tolerances. As a result, the oil filter specifications of the production oil filter and the service oil filter were also improved to meet the new engine requirements.

Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.

Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with ACDelco® oil filters.

Important: The PF64 and PF63, which is commonly confused by many in the automobile service industry as an ACDelco® PF48 and/or PF48E, because both oil filters have a similar appearance and are very close in oil can size. However, these oil filters are not the same size and also have different internal bypass valve opening pressure specifications (PF48/PF48E = 15 PSI (100 kPa), PF64/PF63E = 22 PSI (150 kPa).

Note: Any aftermarket filter must also have an internal bypass valve opening pressure specification, element integrity, filtration performance, media particle trap specification and burst strength that is equivalent to the ACDelco PF64/PF63E filters.

My NAPA guy had not heard. I printed the doc for him and a few weeks later his rep made the changes on their system.

I think GM probably released this bulletin because the bypass valves of the aftermarket filters were all over the board, some as low as 9 psi.  Also, I think some aftermarket filter suppliers had one filter crossing over for both the PF48 and the PF64.

 

As far as using the PF63 or PF64 on a Gen VI 6.0L, I wonder if there would be an issue except for a potential problem if the engine failed under warranty and the dealer was looking for an excuse to deny coverage.  I have cut open and compared a UPF48R and a UPF63R and the only different other than height is the bypass valve spring tension is slightly higher in the UPF63R.  I would not think that would be an issue as long as the can and element of the filter can withstand the pressure of a higher rated bypass valve if the filter was sufficiently plugged or the oil was thick enough (cold start) to cause the valve to open.  In addition, I would think if you used the longer PF63/UPF63 the increase in element area would be less restrictive making the bypass valve less likely to open in any situation.  Ultimately, you want as much oil as possible going though the filter without restricting flow.

I think GM.... I wonder if...... I would not think that......

 

I'm lost...... What was the question you really wanted to ask?

Trying to figure out why GM included Gen IV 6.0L's in bulletin 17-NA-157.
