Mobil 1 M1-212A made in South Korea.

[Hootbro]

Was in Walmart today and swung buy the oil filter section to see if they had changed over to the new Purolator LX gold filters but they still are rocking the FRAM Endurance for now.

They did change over to the new Premium Guard made Mobil 1 filters. Best I can tell, they did a whole reset and left none of the old Purolator made filters. About all were PG made in Vietnam filters but found this one M1-212A made in South Korea.

holes

holes

they're going in the right direction manufacturing wise.

Looks like a simple date code ... 11/15/24 in this case.

Very nice! South Korean PG made filter.

So, M-1 is now made by Premium Guard and not Chump (sic) Labs?

Interesting to see a PG with elliptical holes

Yes. Some Wal Marts and other stores still have Puro made ones so be careful.

Yes if PG is behind this they have one of the MANY factories out of Korea producing a percentage of this Mobil contract... This factory obviously does not use the LEAK TESTED stamp or the typical base plate with holes but you can see the Vietnam version of this below from a recent thread does use the other base plate.

 

[Glenda W.]

It must be model specific because this South Korea PG has the normal baseplate.

Did you notice what the top stamp was ?

No “leak tested”

To me it’s interesting in that Premium Guard makes an oil filter they claim can handle 10k miles OCIs (I’m thinking specifically of MicroGuard Select from O’Reilly’s), yet now we have an M-1 oil filter made by PG claiming 20k mile OCIs.

Clearly those are being made to Mobil specs?

Bad ju-ju from Champ Labs caused Mobil to make the switch?

As to some M-1s from Puro still being on the shelf, unless you’re running OCIs at 12k miles or longer, I say just buy PG’s 10k mile filter and eliminate the guesswork.

Going forward I’m going to use the MicroGuard Select for the 2019 Outback in lieu of the consistently used Napa Gold over the past 50k miles with 6k mile OCIs.

Unless a C&P demonstrates that it’s “darling status” is no longer warranted.

Hopefully someone who is able to can grab one of these and cut it open.

@dkryan Napa Gold is PG made now too. So your covered if you want to continue using them. My only gripe is the price compared to other PG XL filters.

I'm going to call Mobil customer tech line tomorrow and see if I can get an ISO 4548-12 efficiency spec on this new Mobil 1 filter. Will post here what I find out.

Can you ask them to confirm it for the M1-101A as well please?.

Sure, I'll ask if it varies much with filter model.

Thank you, I also sent an email to M+H to try and figure out if there is anything different between the Purolator 20K and previous Mobil 1 filters and what the micron rating is, will share if I get a response.
