Just food for thought. 

 

The difference is the by-pass setting.  The PF48 is set to 15psi, the PF63 is set to 22psi.

 

So in retrospect you would not want to put a filter on an oil system that has high oil pressure because the filter would be in by-pass mode as well as the construction isn't meant for higher pressures. 

 

Now to put a higher by-pass filter on a system with lower oil pressures, as stated the above application, basically will not hurt a thing.  Just means the filter will not go into by-pass until the system pressure is at 22psi.  Which means cleaner oil longer and no dirty by-passed oil.

 

They increased the PF63 due to the higher pressures of the system and to keep the filter from going into by-pass so often. 

 

Not trying to say right or wrong, just looking at it from a different point of view.

 

If you read the TSB, it doesn't say anything about not putting a PF63 on an application that uses a PF48, but the other way around to prevent unfiltered oil from circulating in the system which will cause premature wear.

I just picked up a 2500 6.0 myself and I stuck with the 48series filter but went with the upf48r after reading some good things about them.

Interesting you mention the UPF48R.  GM just sent out a bulletin on using the new UPF63R on the newer V6 engines.  

 

"

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) 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.
Any time an oil filter is changed on one of the above vehicles, it is recommended to use the new and improved filter."
 
Again,  note that nothing is mentioned about it not being able to be used on previous engines, just to make sure to use it on the higher oil pressure system V6 engines.

What I gathered from reading other posts was it had a better filter media then the standard pf48 filter so that's why I went with it. I did see a small increase in oil pressure after install, these 6.0 run pretty low oil pressure as idle it seems.

 

Just getting back in the Chevy truck game, was in a 2017 Tundra before this 2500hd and had a 2014 1500 Silvy before the Tundra.

Was anyone able to clarify if the PF63/PF64 are the recommended oil filters for 2012 and newer Gen IV 6.0L's?  Bulletin 17-NA-157 is a little ambiguous (in typical GM fashion) in that it includes L96 and LC8 (CNG/propane L96) and warns against the use of an oil filter with a 15 psi or lower bypass valve, like the PF48E.  Then it turns around and says use EPC recommended oil filter, which still appears to be the PF48E for these engines.  Now I have heard, but have been unable to verify as of yet, that the bypass valve in the high performance UPF48R is 21 psi.  ACDelco also recommends the UPF48R for Gen. IV 6.0L's, so that might be the 'safest' oil filter to use if someone is concerned about voiding their truck's warranty.  See this thread on another forum:

 

https://www.cadillacforums.com/threads/oil-filter-choice.1090978/page-2

 

For clarification, the oil filter bypass valve opens when the pressure differential between oil coming into the filter and oil going out of the filter is over the psi rating of the valve.  Even with a 15psi bypass valve, the valve should stay closed even with 50 psi oil pressure going into it, as long as the filter is not overly restricting the flow and the oil is of the proper viscosity.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.
