Different requirements for oil filters?

[glenn27]

Morning here-

I have a 2013 GMC  Sierra 1500-5.3 L engine (low mileage -two  owner)--I'm retired now-so I don't drive as much--anyway-just had the oil /filter changed-I have always used Amsoil Synthetic and NAPA gold oil  (#7045) filters-now i read that GM has changed the oil filter requirments for these engines- and they (GM) recommends/ want to go w/ a different filter w/ more psi rating on the relief valve (in the filter) to open like 22 psi.

The above featured one I  mentioned shows 12-15 PSI--which doesn't kmeet these new specs..

 

Wow-stuff is like getting more/more technical all the time. I think it looks like trying to avoid these  sticky lifter problems.

Any thoughts or recommendations here? I'm kinda confused--

Thank you-

glenn

To me it honestly makes zero difference what filter you run. It's not a race engine, just a truck engine that's mostly bumming highways and it just needs a filter that filters oil.

 

The filter used to be a 7060 and the long version was a 7045. Now it's the newer updated filter that the K2XX trucks and newer run, the 100255 I believe if we are using napa numbers. Any of those filters is going to do the job.

 

I wouldn't overthink it, to me it makes no difference because those first filter numbers worked for 18+ years before the spec suddenly changed.

Do you know WHY the filter relief setting was increased to 22 psig? 

 

When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation. 

 

So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp. 

 

Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm. 

 

I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself.

2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.  

 

There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi. 

 

TSB HERE - temp.xml

 

"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 an ACDelco® oil filters"

 

It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.   

 

 

 

That all said...

 

Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

Ok--Thanks for that info--I could not find yesterday when I looked for the specs on that NAPA filter what I wanted. Their website is not very user friendly.

I buy all teh filters for  our three vehicles once or twice a year. Have always run NAPA Gold on everything I own....I buy it thru my Son's account for his business-which he has a Heavy Equipment repair shop-one reason he uses NAPA so much-they have such a full line of coverage for just about anything/anywhere-

He gets s  good discount because of volume bought.

Anyway-Thank you -Sir for your response.

Thank you, also for your  response. More information is always good. This 2013 GMC is most likely my 'forever truck"-I'm 77 and retired...and truck only has 42K on it-very clean-so I try to keep it that way.  Tks again for your  response-

It's going to last a long time. You seem to take care of your vehicles and that is key.  I wish I kept my 2002 Silverado. These new vehicles are not built with quality anymore.

To last poster there in Wilmington, NC--Not too far from our place at Atlantic Beach...what is referred to as "Southern OBX>> I am  a little sad as life  goes on that we never actually moved there when we first visited-44 years ago. Love that beach area-even though I don't move around as quick as I used  to-

Luckily here also--I have a ;local independent shop that will service my vehicle with my supplied  fluids.

I'm to old to lay on the ground  and  do it anymore. The m Shop owner and his Son have been friends for years and we were both in the towing business for many years.

it's good to have support  when you need it.
