Topic: Napa Gold 1365 oil filter superceded by 7712

[snackers]

Just an FYI to those that use the Napa Gold oil filters.
There are a few "what oil filter do you use?" threads, but none of those really seemed apt.

Part 1365 (filter for subaru) has been superceded by 7712.
The new filter apparently has the "subaru required" bypass pressure spec of 23PSI.

I'm not sure exactly when this happened, but the post on SF is from January 2012.

1365 - specifies an 8-11 PSID bypass. http://www.nfhconnect.com/lookup/PartDetail.asp?Part=1365
7712 - specifies a 23 PSID bypass, and lists only subaru as the principal application. http://www.nfhconnect.com/lookup/PartDetail.asp?Part=7712

Note, you can still get the 1365 if you ask for it, as it is also intended for other applications. I had no idea 7712 existed, and have bought a half dozen 1365s since January.

Please discuss only the Napa Gold filters in this thread. There are other "what filter should I use" threads if you wish to compare others or discuss why this $10 filter is not as good as your $23 K&N non certified marketing scam filter when combined with motul certified fairy dust.

It would be really cool to do an actual comparison between the new NAPA filter, the old NAPA filter and the stock filter. I think it would be really hard to get any significant data though.

To what end?
While I don't claim to understand everything about it, a bypass valve is simply that.
I learned some things here:

Or do you mean compare the oil between the 2, and see how much "unfiltered" oil actually gets by at a lower bypass spec? (8-11 PSID on the 1365)

[Ambystom01]

In terms of comparing the NAPA filters to the stock pieces, it would be a quality comparison.

Quality of the build?

In terms of quality of filtering abilities?
There's a thread on nasioc/iwsti/bitog with all of these filters in the "used" state (minus 7712, which would be the same as the 1365) in an attempt (I believe) to see the condition of the filter material after an interval of filtering.

In terms of oil quality after a change interval? I'm not sure there's a reliable way to test this.
There are too many variables.
Air filter (it will be dirtier on the 2nd 5000km, you'd have to change it before EACH test)
Air quality (and air filter quality) (spring air might be dustier than the 2nd 5000km summer air)
Driving environment (dirt road v. paved city life)
Driving style (I might only do 1 autox and highway driving during 5000km, and then 8 autox and city driving on the 2nd 5000km)

I don't know how much the engine itself changes over time, but on my failhatch an oil analysis showed "new engine" gasket material in the oil even after 20,000km. This would skew results if you were doing a test back to back, 15k and 20k.

Yeah that's what I'm thinking, it'll be almost impossible to accurately measure filter quality based on the quality of the oil coming out.

Interesting, thanks for all the links snackers!

There is really only 1 true way of testing an oil filter's quality. It's called a Beta Rating test. Essentially, a manufacture has a test rig set up that they would introduce a stream of particles suspended in oil into the filter. The particles would all be the same size. They would count how many particles actually got through the filter media. I've looked for Subaru filters that have been tested this way, but all the ones I've found are for large industrial hydraulic applications. Here is some info on Beta rating http://www.machinerylubrication.com/Read/564/filter-beta-ratios

The other thing I do to check how good a filter is (construction wise) cut it apart and compare to the stock Subaru filter. It blew me away when we did this in shop last year. Out of 3 we cut opened, the best was a Mopar brand filter, and the worst of course was the Fram.

I just installed one of these.  Maybe I didn't prime the filter well enough cause it took a little time to get to 90 psi on startup.  Everything seems normal now though.  Seems the same as the 1365

anyone else tried this newer filter?   it seems like the oil pressure on startup is slower then the 1365.  the napa I go to regularly has a 1365 remaining so ill test that soon, but im suspicious, since nothing else on my car has changed. 

its especially evident in cold temperatures.

[snackers]

Yes.
On both my cars.

[GrantC]

I'd rather have a filter that meets OEM specs & filters all the oil. Rather than a generic replacement that blows open & builds quick oil pressure of unfiltered oil.

[GrantC]

The NAPA's in Edmonton all seem to have the 1365 still on the shelf.

The 7712's are available at the "main" location at 111ave and 178st, or your NAPA can order them in.

It will stay on the shelf, that filter is also used on other cars, not just subarus

Yes, I know.  Those applications are listed in the links on snackers' first post.

Ford (92-97), Honda (00-06), Mazda (97-07), Mercury (91-96), Saab (05-06), Suzuki (09-13), Cub Cadet, Yanmar, John Deere, Kawasaki, Kobelco, Outboard Marine Engines, Various ATV/ Motorcycle (00-12), Subaru 4EAT, R4AX-EL spin-on transmission filter

Various Subaru (88-13)

I meant to say, _only_ the 1365 is on the shelves & you will have to ask about the 7712.  (And probably drive to the west side if you need it that day...)

So, he didn't post it in this thread.  But canehdianJ figured out what was causing his low oil pressure on startup, and it wasn't this filter...

Thanks for taking care of that for me grant :-)
