Unused M1-211 old stock from 2008

[slacktide_bitog]

The reason I cut this unused filter is because I thought that 2008 would be too old for a filter to use the next time the filter is changed; in fact, there is some rust on the inside of the base plate. I had bought quite a few Zetec filters from Rock Auto since they can be hard to find, but doing so is no longer necessary now that AAP is carrying Carquest filters (red available now, blue coming soon). The CQ Blue is a reboxed M1 at a much more reasonable price. Part #85315.

Some interesting things to note with this old M1:
Date code 050708H1 (May 7, 2008)
Made before Fram took over Champion

Leaf spring only has two legs, as opposed to the 4-legged leaf normally used in Champs of this application (8316/25230/1315); perhaps Champion switched to the 4-legs later on.

The media felt like very high quality stuff, even if it isn't the latest wire-backed synthetic (Fram does not make an Ultra XG8316)

Two anti-siphon valves (ADBV's in the opposite direction). One near the thread end, which is easy to press in, low-pressure. And another at the dome end, very high pressure, rather hard to press in!

The baseplate has six small, standard-sized holes. Newer Zetec Champs have eight holes, and one of them is twice the size of the others. Compare with other cut-and-posts on here of the Service Champ OF5230 and STP S8316.

The thread-end, easy-to-press valve

The dome-end, hard-to-press valve

Thread-end, easy-to-press valve, taken off the center tube

Dome-end, hard-to-press valve, still attached to center tube

i would have used it

There seems to be darkening of the media, which is what I have been seeing in 8-10 year old filters. I don't think it was suitable for use. Not for me anyway, I think it starts to harden up, whatever binders they commonly use. The only start up rattle I have ever heard in an 02 Camry v6 was using an older filter with the small disk bypass valve that opens inward only s short distance. probably smaller than the one you show here. Fram Ultra or Toyota, no problems, almost instant oil light off, never a rattle.

Thanks for cut and post, M1 filter is always look good.

I still have few Honda PCX-004 filters for S2000 I bought around 2005-2006, I intend to use it for next oil changes

So far 2 people would've used it, 1 would not.
{I'm not counting my own opinion in tabulating the results)

You should probably not use them. You bought them 10 years ago. How old are they?

This 8yo filter doesn't look exactly like brand new (base plate starting to rust, media starting to discolor). Get a reasonably new M1/CQ Blue, Wix, or Ultra.

Was the media brittle at all? If you had more than 1, I would have cut one and made an assessment from there. If you only had 1, I would not run it.

I bought two of them. One is being used on the car now, and this is the other one that I cut.

Yes, the media felt brittle, definitely showing its age.

What is the purpose of having 2 ADBV's?

PS: I would have used it. I have used older filters than that (properly stored) and have had very good UOA's.

The second one is flipped around in the opposite direction (as an anti-siphon valve), to keep some oil in the filter, to avoid dry starts which can make some engines grumpy.

The last UOA with the 10-12 years old PCX-004 filter had very low insoluble at 0.1%. This low insoluble means the filter is working well.

Yep ... think of it as an ADBV for the center tube.

Does it? I have read here more than once that filters have little to no impact on the measured insolubles found in a UOA. When I switched from MC FL-820s filters (94% @ 20um) to FRAM Ultras (99.9% @ 20um), there was zero difference in the insolubles in the UOA. Blackstone has said the same on more than one occasion.

Yes they have.

As for this application with adbv and antisiphon centertube valve, the vehicles this filter is designed for must be very sensitive to engine oil drain back issues. This feature is rarely seen.

As for filter, look useable. And though some differences noted, the interior visible coil dome bypass still looks Champ made/design to me.

Yes, this is an issue in the Zetec.

The filter looks usable at first glance, and seemed fine, but I'm glad I cut it and decided not to use it, because the filter media is old and brittle.
