My son should be getting his special ordered C7 in February. Going from a 2000 Honda Accord that he has driven for over 10 years to the C7 will be quite a change. For his first oil change (an early one) I want to give to him the correct oil and filter for his Z51 equipped car. The owner's manual that I've seen online specifies a PH64 oil filter. Another document I've seen online entitled "Service Information Document ID: 3576049 specifically states:
"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."

To be honest, I'm a little confused. Why would this be in a dealer document and not in the owner's manual? I appreciate your help with this issue. Z51 owners, what is the factory installed filter on your car? Thank you for your help.

I used the Mobil 1 Model M1113 Extended Performance Oil Filter.

It exceeds GM's requirements, and is an overall better filter than the ACDelco (non-R) equivalent.

About $13 a pop:

Correct is PF64.

Apparently some cars came with the correct filter but the filters had the wrong label on them. See this bulletin for reference:

never seen dealers do stupid things?

as for using different aftermarket filters - this is not only filtering ability-which most can do great- it's also about keeping correct oil pressure at normal and "blow off".
usually there is not enough info available to clarify whether aftermarket filter is compatible with OEM...
don't be fulled by brand names - do you really think the Mobil corporation manufactures its filters?....

those small and basic things like oil filter, radiator cap and thermostat are better be left alone and not to mess with supossedely better aftermarket parts - as every little problem with those parts may kill the engine.
a risk IMO not worth taking...

Theta

That's pretty patently untrue... many have to be certified and tested before being able to guarantee compatibility. It's not just about fitting a thread pattern...

I work in the oil industry, and I actually know exactly who makes what.

Croc999

so is there any compatability documentation available for us consumers?

Theta

I really have no idea what you're looking for. If you're concerned about compatibility, just stick with stock - there's no harm in this whatsoever.

Particle filtration, flow rates, etc. are available to the public from the manufacturers, as far as I know.

If you're interested, you can view YouTube videos where different brands of filters (for the same application) are cut down, giving you a clear view of the components.

I'm going to give you a hint, though: The OE filters with 'R' at the end, such as the UPF48R, are made by the same manufacturer as the M1 Extended... The non-'R' designations are excluded, of course.

Croc999

yes, those specs i'm talking about.
never looked at Mobil filters but for others i haven't seen this.
also OEM filters don't state this info - so i don't know how can we compare.

Theta

You'll need to do some digging if you're really that curious. It's not easy to pull some of these filter specs.

If you're interested in the above filter info (PF64 and PF48) and the differences in bypasses, look here:

http://www.bobistheoilguy.com/forums...PF64__vs._PF48

You should read up on R- vs non-R-spec filters, as well.

Theta

Here's what I can get you (officially):

ACDelco Pro (non-R):
"98 percent single-pass filtering efficiency at 25-30 microns for excellent filtering capabilities."
"Designed with five times greater burst strength than most engine oil operating pressures after the oil reaches operating temperatures."

Mobil One Extended:
"Mobil 1 Extended Performance Filters are 99.2% efficient at removing harmful contaminants before they reach vital engine parts."
"The durable, heavy-duty filter canister withstands nine times your vehicle's normal oil system operating pressure."

For someone who wanted to remain completely stock, I’m surprised GM doesn’t have a UPF64 option. Don

I'm still a little confused. The owner's manual specifically states PH64. Here is a link to the Service Information Document I referenced in my original posting:

http://www.stingrayforums.com/forum/...formation.html

There is a specific recommendation for a UPF48R but the manual does not show this. What gives? Can anyone tell me what the Z51 had from the factory?

Croc999

Theta, those quotes talk about filtering capabilities.
i'm really more concerned about flow ration, keepin oil pressure and correct bypass.
i've never seen enouh info to be sure that all those are 100% compatible.
so if i'm not sure i'm sure will not want to use it.
why not to use OEM filter?...

Theta

Bypass is easy, that's visible.

Oil pressure is not an issue on this grade of filter, even on base-level stock. That goes for several other brands.

Some of use are just 'crazies' who run magnetic plugs, do oil sampling, etc... You can take a look in the other thread if you'd like to see how marvelous the factory filter is. Enough said.

In that case, I would suggest that you stick with OEM.

Theta

Come on guys... it's being repeated over and over. The correct filter is, as shown on this GM bulletin: PF64

Croc999

Theta, in your opinion what are the advantages of using Mobil1 filter?
or downsides of the OEM filter?

Theta

It's very simple. The M1 equates to the -R designated ACDelco product. That is a higher-quality filter than the standard-level filter.

Croc999

higher quality in what way?
build?
filtration?
something else?

Theta

Oh lord... If you're really needing that kind of detail, call Mobil and ACDelco.

Or, buy both filters (M1 + -R) plus a PF64, cut them all up. Compare and contrast.

I don't have the info you want - I've simply given you the available facts.
