Check out this month's GM techlink issue. Go about 1/2 way down and you'll see the "new" Delco filters...they're ecores.

" smaller, redesigned Original Equipment (OE) oil filter is now in production that offers ACDelco's exclusive Duraguard® media protection.

The new filter applications (GM part numbers 19210283, 19210284, 19210285, and 19210286) are installed as original equipment in applicable new GM models. While performing oil changes on several 2010 GM models equipped with the new filter, such as the Chevrolet Colorado and GMC Canyon, technicians may notice the smaller size of the filter compared to the old design.

The new oil filter features ACDelco's Duraguard synthetic cellulose-blended media that efficiently filters particles as small as 25 microns -- 1/3 the width of a human hair -- to ensure a clean supply of oil to engine components. (Fig. 5, A) It also has a full cover baseplate for easy installation in blind applications (Fig. 5, B), a new nylon core that provides better flow characteristics and improved collapse strength (Fig. 5, C), and a combination relief and anti-drainback valve that prevents dry starts and assures oil flow (where applicable). (Fig.5, D)"


Thanks for the link.

Hmmm. I've been seeing Ecore delco PF61's for quite some time.All the AC's at my Walmart are now ECore's, BUT none of them have an "E" at the end of the part number. Do you think there might be a difference between a PF61Ecore and a PF61E Ecore?

The Wally's in my neck of the woods has PF47 E-cores, but as mentioned they do not have the E at the end of the part number.

I beleive the E is just a newer sticker should be the same internally.

Exactly! Without the efficiency rating, 25um level doesn't mean much. shrug Is it really any different than a ST?

If you google..Champion Ecore design, enthusiasm for the new AC Ecore design doesn't seem to be universally shared.

On another note, take a look at the May 2009 Archive from the above blog. Pretty interesting pics of a failed aftermarket oil filter.

I was at a local Farm supply store yesterday and saw a few AC Delco oil filter boxes with the new "E" suffix on the part number.

Example of what I saw printed on the box: PF61E

I suppose that's natural. (I'm a little skeptical, too)

I knew the old design well and pushed 7,500mi OCI's on them easily. Psychologically, it's a little tough for me to look at the newly designed filter cut-open and picture myself running it for 7,500 miles.

I found some older PF47's and loaded up. By the time I'm through them, the experiences and posted pictures of others may have convinced me that the new design's OK, too.

Certainly their competitors dislike it.

Nah. These are folks that used the old design and preferred it to the new Ecore. Many, like OilNerd, were stocking up on the old design while still available.

Wouldn't know about competitors, though I doubt many are quaking at the thought of competing with the AC Delco Ecore. The folks that prefer traditional endcap design will find other reasonably priced alternatives, lots of them out there. I got nothing against Ecore and have used it, though I prefer metal endcaps and a traditional bypass as opposed to the rubber combo bypass.

Still wondering if the AC is just an ST with a different name.
