When would you not want an ADBV?

It has always been my understanding that even a vertical base plate facing up filter could use a fully functioning ADBV. The filter would certainly stay filled regardless, but that ADBV could be holding some oil inside the engine too.

Looked up Wix/(NG) filter application for topic Mazda Slyactive engine and found several google images of the 5/7002 filter. As noted, same as the factory Mazda filter, no adbv for specific application. So like the Fram EG/(TG) shown earlier for GM applications, they match the factory part with no adbv in replacement filter for Mazda. It would seem imo if maintaining oil in galleries 'these specific' applications critical, no less so from factory as opposed to subsequent service. Again, as ACDelco and Mazda off the shelf filter would indicate, having one even where not factory spec'd works too.

Not an easy thing to be on this website … but I'm predominantly a long term GM owner … don't recall any standard oil filters without an ADBV … and majority of them mounted base upwards
The Cruze is the only GM I have owned with a cartridge

Linked below a Mazda non factory filter with no adbv. And linked is the Fram listing showing all GM applications which according to Fram came from the factory with no adbv. GM models from 2005-2012. Multiple GM factory filter dissections with no adbv have been posted this subforum over the years.

It was a special General Motors application like a police Interceptor V8 or something. Been a long minute since I thought about the details but there really was such a thing per a discussion when I was a NAPA counter-boy in the old days. The first-fit filter had no ADBV but the dealer-recommended replacement filter did.


Regardless....forget the science & theory. There's only 2 ways about it:

1. If the first-fit filter from the factory doesn't have the ADBV, there is no problem with your aftermarket or dealer-service filter if it does have the ADBV.

2. And if the factory first fit filter is equipped with the ADBV (or your manual tells you to use a model which does have the ADBV), you use a filter with the ADBV.

The AC Delco PF61 in 2004 did not wear an ADBV. It wasn't until the GM bankruptcy around 2008 that it did show both a PF61E and an ADBV in the PF61.

Which is basically what my initial post says. I prefer to use the term factory filter ie., filter that comes from the factory as assembly line engine part.

Whether there may or may not have been some undocumented exception, doesn't change the main point. As prior noted and linked, the GM ACDelco off the shelf filter(s) that replace the no adbv GM factory filter(s), have an adbv. That even though the Fram EG/TG equivalent has none.
