Something they've changed in the past couple weeks?

He's actually sort of correct.

The part he said about e-core technology is correct, however this change was made three years ago in 2009. I'm not sure on the metal caps.

He's wrong about the filtering media however. They both use a synthetic/cellulose blend for the media.

This is from Mobil 1 website.

Most conventional oil filters use a filter medium that is made of cellulose – typically wood fiber – and polyester fibers. Mobil 1 Extended Performance Oil Filters combine a mixture of synthetic micro fibers and natural fibers.

And this is from AC Delco's press release posted 3 years ago.

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.

They both are rated at 25 microns and they both have 45 pleats so their filtering capabilities are equal.

There are quite a few of the ACD filters that have switched to the ecore design. The PF48 was supposedly one of them. If you have one from Feb, then obviously it hasn't happened yet. Thanks for the info/correction.

I can't find anything anywhere that says the ACD Duraguard is anything more than patented cellulose media. You got a link so I can be corrected?

I'll eat crow on the Mobil 1. I thought they were 100% synthetic media. The ACD DuraGuard and even the ACD UPF48R are 25-30 micron. Mobil 1 is 10 micron. The rating for the ACD Duraguard is hideous. A Purolator PureOne beats that easily with a rating of 15 micron.

I'll challenge anyone to beat the EA amsoil media filter,, many reports coming back with flying colors on this filter,, and it's under 12 bucks

Here's one from AC Delco's Tech Connect. It isn't the same link I originally had as they are claiming 10 micron filtration. This one does however however show a pic of the ecore design.

This redesign also now effects all filters that have a "E" after the after the part number, instead of just the 4 they list.

I've been using Mobil1 for so damn long that I'll just stick to it.

That's some good info that puts a little truth back into the thread.

The PF48 has never been ecore, and I doubt for performance applications ever will be.

For performance applications, that metal perforated core and coil spring bypass valve are much better.

The PF48 also has one huge advantage over every other filter on the market.

Factory warranty.

Show up anywhere in the country with a motor/filter problem, and you're covered by warranty. Even though I've never seen a single PF48 problem. Show up at any dealer with an aftermarket filter problem.... here's your estimate.

Anything other than the Amsoil Ea series filters is not good enough to go on my engines. Amsoil has the best value on the market for price point compared to quality of products.

Good question, Russell. About to change mine soon, and am heading down to Advance Auto to get a PF48. Thanks for the info..

Right on, Russell. Makes perfect sense, couldn't have said it better.

Out of curiosity, cut open a PF48 tonight out of my Walmart stash. I've noticed they changed the name recently from Duraguard to Professional. I just wanted to make sure none of the guts changed. Looks to be the same as they've been for years. Metal end caps, metal core, rubber anti drain-back valve, coil spring by pass valve, 60 pleats, made in the USA. Pretty decent filter for $3.68 at Wallyworld.

I'd say, there are definately worse out there, and better if you go to a premium filter. But there isn't anything this one is going to do wrong, it's got all the basics. Hopefully this part number never goes to the ecore. You can tell those by the E on the end like a PF47E.

Awesome Russell James, thanks for doing that.
