no reason to be upset - i'm just trying to understand what are the fact base on which you preffer non OEM filter.
correct me if i'm wrong - so far we didn't get enough tech info for that.

Croc999

BTW - as industry insider - what interesting things do you see/know on filters manufacturing or quality?

Theta

I've given you all the required information that influences my personal preference. I am in no way suggesting that you should use anything other than the factory filter unless you prefer to do so. I was sharing info for those unfamiliar with other options.

The part number debacle is already confusing enough for most people. After performing a full oil analysis, I'm personally not comfortable using the normal OEM filter.

That's the bottom line.

Croc999

that's a good info, because IMO the bottom line is what matter.
what "bad" things have you seen at UOA?
did Mobil1 resulted "better" UOA?

Theta

I would suggest that you read more on other forums that deal with your questions at a much more in-depth level.

This is a good place to start:

This will answer your questions on the nature of the differences in bypass, media, etc.

I think this has sufficiently derailed the thread, so this will be my last post on the topic.

You can also go to NAPA and buy a filter. Their best is called the Platinum series, I believe and is made to work with synthetic oils. You just need the AC Delco PF64 number and they can change it over to the NAPA number. A large number of filters out there, aftermarket and OE are made by Guard corporation. However they are made to different specifications.

Certainly, I appreciate everyone's response to my original post. I suppose I'll ask my original question a different way. On another forum, there is a "Service Information Document ID: 3576049". In it, there is this specific recommendation for Z51 equipped Corvettes:
"Engine Oil and Oil Filter Replacement (With Z51 Performance Package):
Caution: This engine uses a special high performance oil filter. Use of any other filter may lead to filter failure and/or severe engine damage. Use oil filter UPF48R or equivalent."
Can anyone tell me if this is a legitimate document? The reason I question the Service Information Document is because nowhere in the owner's manual do I see that the Z51 equipped 2014 Corvette requires a filter other than the PF64 (GM Part No. 12640445).

Larry Myers

The reason the owners manual says nothing about the UPF48R filter is because the manual was published mid last year. However, the service information document is probably only a couple of months old.

I would do two things. 1. Take a copy of the sid to the dealer's Corvette service writer and ask him/her to verify it's authenticity.

2. In the parts dept. ask for a filter for the Vette and see which filter he/she provides. Be prepared to provide the VIN.

I'm leaning toward the UPF48F filter because it's the superior AC Delco filter. Specified on the ZR1 and ZO6.

If the dealer is confused too, ask them to query the Tech Center.

Theta

Agreed, I would use this or the Napa Platinum/M1 Extended, etc. All the same top-tiers.

"Use oil filter UPF48R or equivalent" to me, at least, recommends using the next step up from the standard filter. Yet, they shipped from the factory with the normal blue ACD filters... Who knows...

See what the service center tells you. I still think they will sell you the standard filter, but it's worth a shot.

Is the UPF48R an accepted replacement for the PF64? If so, then you can't go wrong using the UPF48R. Seriously, the service center has likely never seen the Service Information Document. They will almost certainly put a PF64 on the car. It would make me comfortable to have them call the Tech Center and get an answer from them. Otherwise, I guess I'll have to see what the car has on it when it is delivered. Thank you Theta for your help. I realize this should be a very simple issue. I didn't start this thread to debate the merit of one filter vs another. I simply wanted to verify that the Z51 should have the UPF48R filter.

Theta

Here's the answer for this:

From Techlink:

So, I don't believe it's an acceptable replacement for the PF64 based on those specs.

I'm beginning to see more places on the internet mention Service Information Document ID: 3576049 which specifies a UPF48R for the Z51 equipped Stingray. I also sent a pm to Chevy Customer Svc but haven't heard back yet. I would still be interested to know what comes on the Z51 from the factory and I'm surprised to not hear from someone who has done an early oil change on a Z51. At this point, I plan on using the UPF48R since it appears to be the one GM specifies (IF the document I see on the internet is legitimate). Should I hear from Chevy in a private message, I'll let everyone know. Thank you for all your input.

Theta

Oh, my Z51 came with a blue PF64 installed on it, and the engine oil thread has more info from the change.

VThokies

My Z51 had a PF64 from the factory.

Theta

And now we have a pattern.

Before you get too far away .... close kin to the correct filter is the correct oil. As per the C7 owners manual GM blend is recommended. Corvette Racing uses Mobil 1; Mobil 1 was recommended by GM for my C6.
This tells me that Mobil 1 oil is regarded highest .... but for less stressful use GM wants to make money off of their blend.
Translate that to filters: I would bet, but do not know for sure, that Corvette Racing uses Mobil 1 oil AND Mobil 1 filters. That would be worth checking out.

bnall40

FYI : If you were to order a C7 oil filter from Amazon and run the compatibility check Amazon will tell you that the UPF48R will not fit the 2014 Corvette. Amazon not distinguish between Z51 and non Z51. Amazon says the Mobil 1 M1-113 will fit the 2014 Corvette. Again no discussion of Z51 and Non Z51

bnall40

Bottom Line:
It appears that for everyday driving and cruising the OEM Blend and OEM PF64 filter is what we want.
For track and racing GM specifically recommends Mobil 1 oil.
I would think, but don't know for sure, that for track and racing GM would probably recommend the Mobil 1, M1-113 filter for our C7s.
Corvette Racing, no doubt, has the answer on that.
From what I have determined, above, the UPF48R is a No-Go.

bnall40

A last thought:
I am aware that the conclusion, above, conflicts with service bulletin ID: 3576049 .... which was the genesis of all of this discussion in the first place.

Here is a cross reference chart:
http://www.oilfilter-crossreference..../AC-Delco/PF64
This chart adds to the confusion. It shows the PF64 can be replaced by many filters including the UPF48R as well as the Mobil 1 M1-113. The bottom line is that I have ordered Mobil 1 M1-113 filters from Amazon and I will buy Mobil 1 Extended Performance 5W-30 from Wal Mart. Nowhere has anyone suggested that the M1-113 won't be an excellent filter for this application. An early oil change will be done at around 1000 miles as I've done with all my new vehicles. It really shouldn't be that complicated but Chevrolet hasn't made this easy. My private message to Chevrolet service has not been answered. The service document that I've referenced which suggests a UPF48R is confusing because those who have Z51 equipped C7's have reported their car came with a PF64. Chevy really should clear this up. We've all spent too much time trying to resolve a simple inquiry. Thank you to all for your help.
