AC Delco PF1250-15243ES-13:37 - Used oil filter cut & post

Oil and filter changed on 04/16/2016

2004 Ford Ranger 4L V6. Miles on vehicle: 150,432 OCI/FCI: 4900 miles

Out: MS5K 5W30 and AC Delco PF1250. No startup rattle was observed with this combo. OCI/FCI 4900 miles. No makeup oil added. I cut the filter open. Everything was in order.

In: MC Premium synth blend 5W30 and WIX 51372. It took maybe 3 seconds to fill the filter and galleries. As noted from the startup rattle ceasing. I think I will fill the filter next time.

Problems: gasket stuck to the mounting base. The o-ring on the drain plug stuck to the pan also.

Date Code: 15243ES-13:37 translates to Aug 31, 2015

AC Delco PF1250-15243ES-1337-2 External base plate

AC Delco PF1250-15243ES-1337-3 Internal base plate
All holes in the base plate were effectively deburred.

AC Delco PF1250-15243ES-1337-4 Combo valve #1
Dome end view of the combo valve. The rubber was beginning to harden and take a set.
It took quite a bit of force to remove the combo valve from the body of the filter.

AC Delco PF1250-15243ES-1337-5 Combo valve #2
The imprint from the inlet holes show the combo valve and filter were centered.

AC Delco PF1250-15243ES-1337-6 Media #1
Pleat spacing is even. No media tears. End caps firmly attached.

AC Delco PF1250-15243ES-1337-7 Media #2
Pleat spacing is even. No media tears. End caps firmly attached.

AC Delco PF1250-15243ES-1337-8 Media #3
Pleat spacing is even. No media tears. End caps firmly attached.
Other filters of this style have nubs on both the top and bottom caps. This one has nubs on the thread end cap only.

AC Delco PF1250-15243ES-1337-9 Leaf spring
Leaf spring and internal view of the can. No rust.
It took quite a bit of force to remove the leaf spring from the body of the filter.


In conclusion, this filter served well for 4900 miles using conventional 5W30 oil. There were were no tears. No startup rattle was observed. No leaks were observed. The filter was over priced in my opinion. However, they can be mail ordered for about $3 plus shipping.

+1 ... only comment I have is the mention of the combo valve seemed to be getting hard at take a set from use. Not sure if I'd like that, and unsure how that might affect the functionality of the combo valve.

This is one of my concerns. I had a test planned to see if the ADBV function was good but, I botched the experiment. Another experiment will have to wait for 6 months. WIX is on now. All that I can say at this point is that I did not observe any startup rattle.

This is pure speculation on my part but, as the nitrile rubber hardens, I think the ADBV function is degrading and degraded relief valve function would be sure to follow. I believe relief valve function would be more important than ADBV function.

From what I can see, this filter trumps the FL820S that tore. When this was discovered, I over reacted and started looking at the eCores. It looks like they will do just fine for the 5K OCI/FCI specified by Ford.

Better choices include:
Fram Extra Guard - separate bypass valve so the ADBV rubber can be tweaked.

Fram Tough Guard - silicon ADBV and separate bypass valve + 99% filtration efficiency @ 20 microns.

Fram Ultra - silicon ADBV, separate bypass valve + 99% filtration efficiency @ 20 microns and wire backed synthetic media for long OCI. Overkill for me.

NAPA Gold, WIX - silicon ADBV, separate bypass valve.

Mobil 1 filters. Overkill for me.

and ???

This oil and filter was looking so clean, I am thinking on a UOA and maybe extending some with a full synthetic.

Maybe it will get the Fram poppet valve treatment like some of the other Ecore filters. From reading the ACDelco Tech Connect papers, the poppet valve is a better design, and it performs better too.

BigD1 - Thanks, cool video. Sure to bring out the trolls.

I confess I do have a PH2 and TG2 in the stash to run and cut.

I will be fitting one of these to my Toyota later today.

It was one of a bunch of low cost filters I bought from Rock Auto last year.

I'm glad to see it appears to be a reasonable filter, because from an outside examination, the fit and finish did not seem as good as some of the Chinese made filters I bought.

This PF1250 is the new design with the new cage. The new cage has 8 vertical ribs vs 4 for the old one and a couple more rings also. The paint job is as good as any filter.

I bought a half dozen PH820 from Rock Auto and they are all old design cages. The risk of media collapse is greater for the old design than the new design.

there wasnt any vibration while they did all those million test?

 

[BigD1]

That's why I would not buy the Champ branded Ecore PH51A filters from RockAuto for a $1.41 each. I bet they have the old cage spacing design, and I just don't trust that. I have more confidence in the latest cage design.

 

[WellOiled]

I have just enough PH820 to do a 4k on 1 filter plus 3 k on the second filter and just top up the same oil. If 4k run looks good, use the last one on a 5k run. Then don't buy any more.

GM obviously thinks the poppet bypass is more reliable as they've said no to combo valve use in the specifically designed for GM ACDelcos. As for the non GM getting the poppet bypass, wouldn't bet on it any time soon. Quite certain the separate poppet bypass is a more expensive to produce and the ecores generally designed as value/jobber/low end tier filters.

This one looks to have gotten the job done ok.

Thanks for c&p.

+1 to both of you. A separate bypass is the way to go. It seems obvious to me Fram/Champ wants to market at many price points. There would be no point in changing the basic eCore.
