Three Ultra-8 (Nippon) ADBV "failures" in a row

Back when Fram consolidated their filters for Nissan from PH3682 to the PH3614, I looked for alternatives. I thought I'd struck gold with the Ultra-8 line from NAPA, only $5 or so and as a bonus silicone ADBV, can wrapped in plastic and the pretty blue Nissan OG paint scheme. The problem with these is it takes 6 seconds for the oil pressure light to go off. I'd get a light jiggle or rattle chain slap, not a concerning knock so I didn't worry too much about it, but with the third filter and 2 changes at 5,000 miles each I wasn't too thrilled with all of those cumulative "dry starts." I somehow through searching ended up finding that the genuine OEM filters are still available through the dealer and they are cheap - under $8 and made in Japan (unlike the Ultras made in, well you know where). They had to be ordered, and picked up at my local dealer. A couple of hundred miles into the new OC I switched out the filter and astonishingly (or not), the light now goes off just about instantaneously, or a second at most. Not bad for an untouched engine with 365,000 miles. I suppose it can be argued that all of those so-called dry starts didn't matter and yes, I am aware that there is oil on all surfaces in any event.

On the other hand, their air filter line is impressive, excellent sealing gasket and with a metal frame just like G*d and Nissan intended, unlike the floppy offerings from Fram and the others.
 
It does read like some kind of adbv issue. The fact that you had improvement after changing the filter, would seem to lend credence to your conclusion. Glad you got the Nissan OEM made in Japan though. I found an adbv design defect with c&p of the Grupo Gonher made Nissan OEM that allows the adbv to slide on outlet tube toward the endcap and flip direction. Making the adbv useless and opening an oil bypass area. Then found a couple other c&p posted where the users had no idea that's what happened.
 
While we all know there are good aftermarket filters, a story regarding such an improvement by using an OE part number carries the day.

On friends' cars I've used OE filters a bunch of times just to eliminate the dopey conversation which could follow a clattery start-up.
Plus, I don't want a clattery start-up.
