You may be happy to know that the new engines have an adaptor that
repositions the oil filter with the threaded end straight up which makes
an anti-drain valve unnecessary and changing the filter less messy.

Your "bet" is hollow since you don't know the cold driving habits of
99.99% of your fellow drivers.
You have made it quite clear that your intention on this (and other

Even a perfect filter/anti-drainback valve won't prevent at least one
valve lifter (lash adjuster) from leaking down over time if the engine
stops with valve spring pressure on that lifter. It takes a few cycles
of the engine to pump a collapsed lifter, so a perfect anti-drainback
valve and completely full oil galleys won't prevent that first few
seconds of tapping. IOW - I don't know that I'd blame the oil filter in
that situation.

I have a "dumb" question for you: Since a liquid will seek its own level
without special means to guarantee otherwise (such as an anti-drainback
valve), without an anti-drainback valve, what's to prevent the oil
galleys from emptying out when the vehicle sits overnight (assuming
there's enough clearance somewhere in the upper lube system to let air
in as gravity pulls the oil downward)? 8^)
I will admit that at least the filter will not have to be filled at
startup if it's not tilted, but the galleys will still need to be
filled. An anti-drainback will prevent even that.
Curiously, the Purolator (and I assume the OEM, which I believe *is*
made by Purolator) for the new engines do not have an anti-drainback
valve (one of the few filters of any brand or application that doesn't),
but all other brands (including Fram!!!!) for that application do have
anti-drainback valves. Saves the Purolator and Subaru $0.05 per filter
with only slightly increased dry run-at-startup time over having the ADB
valve. Probably no big deal over the life of the engine, but the purist
will want an ADB valve even for that application.
