If you search here you will find unkind reviews on Fram. Not wanting to start a "he said, he said" oil filter thread, but it seems it is already here.

Enjoy the ride.

Also worth checking some of the oil filter autopsies you can find online. Fram seem to suffer from poor build quality, inadequate filter media, faulty anti-drainback valves etc,

I am not arguing which is better but if it is good enough for Porsche it is right for my customers so I sell OEM Mann.
We sell the OEM Mann for $8.95 and it comes with the drain plug sealing ring.

I also sell plenty of the Red Porsche oil filters which are made by Purolater for $12 and they also come with the sealing ring.

I struggle to see a problem that needs a solution when we have a solution that has no problems for 9 bucks.

That is not to say that oil filtration cannot be improved - I just do not see a need for such- either way good luck to the OP with the quest- there are always things to learn.

I don't think this would be an issue, as the oil bypass valve should handle this scenario.

As long as you don't mind unfiltered oil lubricating your engine... But seriously, interesting question!

For the first 5 - 10 minutes, until the oil warms up enough to flow through the filter?

I'm not going to worry a whole lot about that.

Really, that's the worst time, when any unfiltered sediment or particles have settled to the bottom of the pan right below the pickup.

Really, the fact is that there is no filtered oil running through the engine since as soon as it leaves the filter and touches anything it is contaminated and then gets worse as it runs through the engine back to the filter. It is pretty much like buying a new car. No one drives a new car since everyone is driving a used car. It becomes a used car the moment it leaves the showroom floor, or maybe even the moment it leaves the assembly line.

It seems Royal Purple are making synthetic media oil filters, but does anyone know if they make one for the 928?

Does Sheisco make one? I heard they have a new "coal media" filter that acts just like putting coal directly into the oil filler. Not sure how anyone could top that.

Unless I've misunderstood this diagram, there is never any unfiltered oil passing through the engine

All the oil flow is filtered irrespective of whether it has been through the cooler or not.

I like using modern AD08R tyres on my cars, and I'd like to use modern oil filtration too if possible

Can point to a filtration problem that needs solved?

My engine has quarter of a million miles on it

If I can get those bearings to last a little longer by using a $20 synthetic filter, rather than a $9 paper filter, then I reckon that is money well spent
