No e-core Mobil 1 and K&N filters, why????

[SilverC6]

Looks like AC Delco is marking their new e-cores on the box with an E after the normal number.

PF46E, PF47E, etc.

But they are still slipping them into the non e marked boxes.

I also found a small supply of non e-cores in the PF46 size. I believe I'm going to snag them while I still can.

Why do they separate the metal?


Once the metal is separated it can be scrapped. When it's integrated it goes to a land fill at cost with more residual oil. It may be declared hazardous waste in some states. Either way the oil has to be drained. I'd say it's an evolution in avoided costs.

The current method in my state at least for all I've observed is draining and throwing it in the trash. I'm uncertain what a quick lube or dealer is required to do due to the volume of filters.

Me too. I mean here, too. A friend of mine is a Geologist for the state of Maine. He tells me that landfills are built to contain this amount of oil contamination for domestic trash. I do see OFs at the recylce place though and like to drop mine there with the oil.
Metal itself, IMO is less of a contaminant than nylon, as it will corrode to iron oxide dust eventually.

I'm sure this has been discussed on another thread before, but for those of us who've yet to find that thread:

what is an "e-core" filter and how does it differ from the PureOne, Wix, etc?

The Ecore was an evolution in spin-on filters brought to market by Champ Labs. It contains no metal internally. It is, last I knew, limited to filters 3" or greater in diameter. This is due to only being produced on one line and there apparently being technical limitations to the "cattle chute" that the cans travel through if they're smaller.

There are no upscale offerings of this product line. The best version available would be probably be the AC Delco versions. Champ makes or has made most of the OEM assembly line filters and has made the UPF line for AC, at least in the past (probably now if they're made at all). That could cause one to believe that AC Delco Ecore matches the OEM spec's if not the standard "meets or exceeds" thingie. Much like MC is Ford's OEM aftermarket product line ..and that they, of all interests, would have a custom labeled product conform to their desired spec's.

There have been several adaptations to the Ecore. GM owners observed that they initially retained the combo valve when no bypass was required on GM installations. Shortly thereafter, the second set of holes disappeared. Later, since they have a protruding thread (not flush) a secondary plate was included as an installation aid. This too, I think, was not for the consumer's benefit, but for the service trade ..but that could just be my personal bias. One or two too many cross threaded legal whines could have forced the adaptation. They could be a real bugger to put on.

In general, I find it a clever design. It would be nice of they offered a silicon combo valve and distinctive fine media ..but.. I really don't think that was what they had in mind from the beginning.

In much of the world, people know better than to entomb metals and fuels in land fills. The metals are extracted and the rest burned to produce energy. Once the end plates and shells are removed, the rest of an ecore can be incinerated in such a way to minmumize air pollution. This is the future. When was the last time you saw a glass milk bottle? There will be those that cling to their steel end plates to the bitter end. Or maybe some people will decide they aren't important when another brand drops them.
