Just wondering what material makes a better ADBV in an oil filter. Nitrile resist chemical damage better but silicon stays more flexible in temprature extremes???
Poll: Nitrile or silicon rubber better for ADBV?

I prefer a filer with Silicon. But if you are using it for a moderate OCI like something that resembles the factory recommendation it really does not matter.
For short OCIs, nitrile is fine. But silicone is also much more flexible in cold weather, so short OCIs in cold weather it would be better to use silicone. Just use silicone all the time and you won't have to consider much. "Silicon" wouldn't make a good ADBV.

You are correct sir, silicone is a much better material. Sorry guys for my errant spelling.

If you have a non-vertically mounted filter-silicone is the way to go. My bro's old Tercel had a pretty old AC Delco filter on it when he bought it-and it made a (un-)healthy rattle every time it was started-and changing it with a Super Tech filter eliminated it, and the ADBV was shot on the old one. He drives it enough that the cheap filters will be fine & get changed often enough-but a silicone ADBV wouldn't have done that.
I prefer silicone, but I've used a lot of nitrile equipped FL1As without any problem. I do get a bit annoyed when the nitrile equipped filter (Wix 51358) costs more than the silicone equipped filter (Wix 51356 and 51365), mind you, but that's another rant.
Back when I had my old LTD, you had a choice of a nitrile ADBV or none at all. I stuck with Motorcraft or AC Delco at the time, since both had it, and the AC was nice and cheap.

High end filters almost always have silicone ADBV. That ought to tell you something.
OTOH - how many real-world examples of vehicles have ground to a halt because nitrile failed where silicone would have saved the day? The ABDV, after all, helps hold oil up in the engine for start up. But the advantage to silicone really only shows up after really long OCIs, or really cold temps. Does anyone here have an engine that experienced a true failure because of nitrile? I personally have heard the anoying tick at start-up from a nitrile ADBV that allows drainback. But the used oil analysis at the end of the OCI was still totally normal, and revealed that my fears were well overblown.

Premium filters generally use silicone rubber.
This is one of their advantages.
I suppose it depends upon your application.
Some engines will show some start up noise with some oil filters.
With an unpicky engine, on typical OCIs, it probably makes no difference.

I think that you brought light to one of my thoughts here in that in extreme temp climates, it could possibly make a difference in "cold" starts as silicone would remain flexible and therefore seal better keeping the filter from draining out.

I'm under the impression that Fleetguard, Baldwin, and Donaldson filters all use nitrile. I may be wrong about that. But if I'm not wrong, I would find that interesting since it seems like those filters target the commercial market.

Ford recommend the Motorcraft FL820S and the FL500S for just about every vehicle sold from 1991 on. There must be a reason why they spec the more expensive silicone ADBV...

They may operate under the assumption that commercial vehicles will have less cold start cycles. If the engine is almost never off except for refueling or repairs, a nitrile ADBV is more than adequate, and no ADBV would be sufficient.

Don't filters on most commercial applications mount threaded side up?

Motorcraft does offer some of the least expensive filters with silicone ADBV's. I can pick up A FL400S at AutoZone for $3.69, just 10 cents more than a STP S3600.

Just a thought ... but I wonder if there are different formulations or grades of nitrile making some of them better than others.
On the new synthetic media Puroltor, it shows to have a silicone ADBV, but it also shows a "premium nitrile" gasket. Could be some nitrile is better than others.

I always prefer a silicone ADBV if it's available on a decent filter.

I believe that a percentage of silicone is sometimes blended with nitrile to improve it's properties.
