AC Delco PF48 to PF63

[TooTall1]

I'll tell you what confused me; I owned a 1999 silvy with a 5.3 and recently bought a 2008 with a 5.3. Rolled under my new truck to do the first oil change and couldn't find the drain plug at first.

[2007SierraSLT]

Every vehicle I ever owned from my 88 Ranger, My 2006 pontiac g6 and now my 07 sierra, I always used a bigger filter...ALWAYS

 

I know well enough to known a bigger filter WILL NOT cause engine failure... bigger filters have more filter media, hold more oil which extends oil change intervals, lowers oil temp etc... many benefits...I used/use the wix 57045 extended filter and it pretty well lines up with the bottom of the oil pan, and not hang super low where it's gonna get smashed off

 

In my days as an auto tech, in school for auto tech and hanging out at my local garage have I ever seen a destroyed engine because of a bigger filter... Jesus, I even run a bigger filter on my girlfriend's lawn tractor

 

If you guys all want to sit here and do everything GM tells you to do, go right ahead, I sure won't... with a 5.3 the more oil the better because all they do is burn it

My post from a year ago:

 

From all that I have read the filter characteristics appear to be the same (relief and anti drainback valves). And there are a number of new GM models that come with the PF63 that say replace with the PF48. So they both have the same threads. This topic has been discussed before around the net. I will be changing to a PF63 with my next oil change.

Did some more checking and found the specs:

 

PF63

Product Type Full-Flow Lube Spin-on

Anti-Drain Valve YES

Gasket I.D. 2.45"

Gasket O.D. 2.76"

Gasket Usage Base

Product Height 4.06"

Product I.D. 22mmx1.5mm Th'd

Product O.D. 2.98"

Relief Valve Setting PSI 9-15

 

PF48

Product Type Full-Flow Lube Spin-on

Anti-Drain Valve YES

Gasket I.D. 2.45"

Gasket O.D. 2.76"

Gasket Thickness .19"

Gasket Usage Base

Product Height 3.33"

Product I.D. 22mmx1.5mm Th'd

Product O.D. 3"

Relief Valve Setting PSI 9-12

 

Seems like the only real specification difference is Pressure spring valve setting (9-12 PSI vs 9-15 PSI) IMO, not a real difference.

Oh, and they say a picture is worth a thousand words.

Tell us more how your extra 22mm of media makes your engine awesome.

Well tell me what ill effect it's going to have... Every little bit makes a difference, If MY engine can hold more oil, even if was only 1/4 to half a liter more or even less, that's good enough for me... Plus even 22mm worth of filter media is better then nothing... every little bit helps. Seems like a lot of guys don't see it like that... The 48 is fine but many guys choose to run the bigger, I do and no ill effects... But nobody can go around saying engine failure or whatever can occur, it's foolish

[2007SierraSLT]

Like the picture shows, it's not that much longer that it hangs below the pan, I think it's right inline with the bottom... still not low enough to cause much concern

I don't understand what the argument here is. To those that are against it, GM did change the filter on some of their vehicles already to the longer, PF63 over the PF48 to correct some issues they were having with the 3.6L engines, so what 's the big deal to those that want to run the same filter to get the same benefit in their truck? From the picture that has been posted it doesn't appear to even hang below the oil pan.. it's not even flush with the bottom of it. Seeing that I am going to return the two PF48 filters I bought at WallyWorld and use the case of PF63 filters I got from RockAuto on both, my truck and Enclave.

 

FYI, I got 12 PF63 filters for just under $50.00. I found that it is cheaper to buy the PF63 filters (sold individually) over buying the PF63F (sold in x-quantity). Plus google search for a 5% discount code, they always have them. This one is good until 11/17/2013 - 1293150810572968

Yeah, i like the longer filters too. I used to run a PH13 in place of the PH30 on my Gen l small blocks. What about those magnets that go on the oil filters,anybody have any info on them?

Why the harsh attitude? There is no right or wrong in this issue, just a difference of opinion. Instead of belittleing someone elses opinion; why don't you defend your position on how a smaller filter with less media and oil capacity is superior to a longer version of the same filter?

Those are one thing I've never used... To me the magnet could fall off and all the metal particles if that happened would become dislodged and could end up back in the engine... The magnets seems quite strong though but I've never used one

The magnets are really strong, the one i posted in the pic is a take off from my old 94 z28. Got it free from jegs for ordering a bunch of stuff. It just happened to fit on my Sierra as well so i transferred it over. Trust me there's no worries about that thing falling off, i've gotten my finger stuck under it while putting it on a few times and it gives you a good bite. Another good benefit of the magnets on our engines is that it also will keep the filter from spinning off if you happen to not tighten it enough.

If you have metal in the oil filter you have more to worrie about than if a magnet falls off.

[worktruck2011]

Just because you think it's to small doesn't mean gm engineers don't know best. Use what is required or don't complain when you have a possible issue related to using wrong parts

I don't believe that's true:

 

 

 

The ACDelco PF64 oil filter installed by the factory meets the specifications of the ACDelco PF63E, but due to the length of the ACDelco PF63E oil filter can, the engine plant cannot build with it because it currently interferes with the assembly line process. http://sandyblogs.com/techlink/?p=4518

Actually on the contrary...PF63 was put on then because the 3.6 was revised with tighter internal tolerances.

 

The purpose of this bulletin is to reinforce to the Service Personnel the critical importance of using the recommended replacement ACDelco® PF63E oil filter that is specified by General Motors for these V6 engines when servicing them in order to ensure proper engine oil filtration and engine performance.

Beginning in 2012 the V6 engine was redesigned with tighter engine tolerances. 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.

 

Another case for using the filter called out by the service manual is on new trucks (K2xx) for oil pressure concerns:

The correct part number is PF63 89017525.

The PF48 oil filter will fit, but can cause the oil pressure to go low and DTC P0521 to set.

PF63 part number 89017525 is for the GEN5 V6 and V8.

 

 

Just because they screw on, doesn't always mean they are the right filter. Engineers may seem stupid but clearly they are not.

I don't remember exactly the filter numbers, but when I had my 83 GMC S-15 with a V-6, I bought the AC Delco filter that was a little longer than the one that it calls for. Of course they were always on the shelf so I had no problem getting them.
 
The reason was, there was more filter area in the larger filter, and I don't know if the cost was any different or not.
 
I still changed the oil every 5,000 miles and never had a problem.
 
I could see that they would use a smaller filter to aid in assembly line processes, and changing to a larger one wouldn't do any harm as long as it doesn't interfere with anything or hangs down where it could get hit by something.
 
If I still changed my oil myself, I might do the same thing on my 09 Silverado unless it would cause a problem like stated above.
