Efficiency Info on the New Mobil 1 Filter

[john_pifer]

It's shown as 99% @ 25u on O'Reilly's website.

Didn’t you or someone else say that the PG and its rebrands are 99% @ 20 microns and 99.5% @ 25 microns?

I think someone called for clarification?

I called PG because of this confusion. Official ISO numbers for PG made 10K filters are:

98.7%@15 microns
99.5%@20 microns
99.9%@25 microns

Marketing from the various brands decides which to publish. Service Pro shows all.

I've never seen this brand before. Where are they available from?

All of these filters are under the PG portfolio.

There’s some duplicates and some missing but here is the PGI brand portfolio. Some may not be the extended life version.

Pentius PLXL4967 open end view. Maybe 1-2 mm gap by eye, or about 1/16”

^^^ Think you posted in the wrong thread ... no discussions of the gap here, but was in another thread.

Shouldn’t Mobil 1 stick to oil? Is anyone really buying their credibility as a filter maker?

Well, the key point to remember is is they are not a filter maker. They are simply a filter reseller.

To add, Mobil defines the specifications their filters shall meet. That was mentioned by Highline Warren when I correspond with them. Same goes for any company that hires out a filter to be made with their brand on the can. Mobil decided to stay with 99% @ 30u for the new Mobil filter supplied through Highline Warren.

Mobil 1 also specified a black base gasket, probably nitrile. it would be nice if they said they are tested here in the USA to M1 specs. Otherwise why buy them?

I don’t like the price but it’s the best Wally option currently.

I can live with 97% X 20u if knew all oil passed the media …
Shame that we don’t always know that …

No leaf spring in the new M1 filters, so highly doubt if there's any amount of leakage past the media. Some models may have a leaf spring, but the bypass valve is still built into the end cap. Same goes with all the PGI type constructed filters without a leaf spring and the bypass valve is always built into the end cap.

I didn’t know Pennzoil was still selling oil filters. Looked them up, they do, must be to service centers mainly.
Seems to me numbers are allover the place. Why not put the Pennz HE in Walmart if they do so well?

 

[MetalSlug]

For the real world, how much is really different between 99% @ 20u VS 99% @ 30u .

Should I loose sleep over it ?

I keep told myself I won’t go down to this rabbit holes , but here I am asking question..

Efficiency of 99% @ 30 microns is basically in the middle range for automotive oil filters. Personally I wouldn't use a filter with less efficiency than that. I like the 99% @ 20u to 25u range. As mentioned, since the Mobil 1 isn't a full synthetic media, and it's rated to for "up to 20K miles", seems they went with the 99% @ 30u efficiency so it can handle that max use rating. Personally, I'd only run the Mobil 1 to 10K max.
