I don't believe I've seen this before in the 30+ years I've been doing oil changes - my filter was dry ... empty of oil this morning during its change. What is this, a bad drainback valve??
~*WAS NOT A MOTORCRAFT PRODUCT*~ Though the new one this morning was/IS!.
Thx,
glenn ...
Filter being replaced was an Advance Auto TotalGrip

Ill bet that Advance Auto TotalGrip was a house-branded Fram (Honeywell).

And I'd bet you'd win that bet.
Interesting how this occurs (if it is indeed a faulty anti-drainback valve [?] - there was no evidence of leakage on/around the filter) - considering that the filter is mounted at an approximate 45 degree angle downwards (?). Are "we" suspecting this to be the cause of the situation (help me out here gang)? There's no chance the oil could be by-passing the entire filter ... could there!?!
If the filter was bad, I reckon I got what I paid for at Advance - I picked it up on a "Buy One/Get One" Promo

I must be missing something as I don't see how the filter could be at fault if the oil never reaches the filter, Fram clone or no. jd
My bad for not stating things more clearly.
There was "evidence", or traces ... residue, of oil having been in the filter (though come to think of it now, that would be the case from even before I installed the filter as I pre-fill my filters ... have for 30 years) - it's just that there was no real volume of oil as one would normally find upon removing it from the motor.
Thinking a 3rd time now, the small amount or residual oil seen in the bottom of the filter - it was dirty, not the clean oil that I poured in during the last change.
So, I suppose what I am asking is: would a faulty anti-drainback valve, or a bypass valve - INthe filter - cause this condition? Alternately, what else could/would cause the filter to be virtually/nearly empty upon removal??
Again, the filter was nearly "empty" (perhaps "dry" was a poor choice of wording) - not full of oil as would normally be found upon removal.

I believe you're right in thinking it's the anti-drainback valve. Was it a while between when you drained the crankcase and removed the filter. I can't remember which vehicle it was, maybe a '81 Bronco with a 351M, but the filter was practically horizontal. (My '83 302 isn't much better) To change oil on that one I would sometimes dump the pan in the evening when the engine was warm and let it drip overnight. When I'd take the filter off the next morning it would be empty and I'd have a whole lot less mess to deal with.
Seems to me the problem is likely a faulty anti-drainback valve.
Because it seems to me, if the bypass was faulty & the filter was in a constant by-pass mode, but the anti-drainback valve was working, the filter would have been full of oil.
Seeing as how the filter is mounted in a 45 deg downward angle, a faulty anti-drainback valve, would let gravity empty it upon engne shutdown.

I understood the AA TotalGrip filters are made by Purolator. Essentially they are "similar" to the Purolator Premium oil filters but with a "grippy" red paint. The PP oil filters use a Nitrile ADBV. Not good for longevity but it should go the short haul, ie 3,000 miles. But the base Fram oil filter uses a Nitrile ADBV and from my experience it sucks from day one of installation. I cured my oil drainback dry start up noises by simply using Motorcraft oil filters on my Ford vehicles. And ironically at WalMart Motorcraft oil filters are less expensive than the base Fram oil filter.

Yes sir - it is the one with the "grippy" stuff on it (which is a nice feature - for install. & removal - I must admit) - but if it doesn't much work well (do what it SHOULD do) past 3000 miles (and as I believe my oil easily stays "good" for 4-5000, well, what's the point).
I'm back to Motorcraft, and Advance Auto; "Thanks but NO THANKS"! You can keep your; Buy One Get One "Free".
Am still curious though if anything else (oil pump, clog/blockage, etc.) could have caused this??
Thx.

Typically you should run the motor for a while before changing the oil. This is good for a few reasons: 1) it gives the oil one last chance to collect any crud in the engine, 2) it prevents any crud in the oil from settling and refusing to drain out, and 3) the oil is thinner and drains out quicker. You just have to be careful not to burn your hands. I usually drain mine after the trip to the parts store and back after I buy the oil.
If the filter didn't have any oil in it after sitting overnight, then it sounds like the filter drained back. This is pretty typical for old filters, especially cheaper ones like Fram or parts-store brands. I almost always stick with Motorcraft filters; however I have had a couple of those drain back as well in the past. You can tell because the engine will knock really hard for a couple seconds when you start it first thing in the morning, then it smooths out.

Roger that. I normally ... I'd say somewhere in the neighborhood of 99.9876% of the time ;] ... do perform my oil changes after a warm-up of some sort - but needed to do this one prior to a long trip and was short on time - so I just jumped on it (was actually a nice change being that the oil was no more than 'room-temp' warm!).
I don't ever recall - in over 30 years -and performing, I don't know, somewhere in the neighborhood of probably '500' (?) oil changes, seen this happen. At least I never recall it happening - though probably half or so of those changes were done in various garages I've worked in - and I either never thought about it - or just plain didn't know any better (wouldn't have known to be on the look-out for much less notice something such as this - so as to mention it to whomever [owner/boss/etc.]).

I no longer drain them warm, unless the weather is very cold. I would rather have oil drip off the internal parts overnight to get more of it out. Also, modern multigrades flow out of the pan just fine when cool. Getting ones hands burned by touching an exhaust manifold while trying to loosen a filter is no fun (Ford 5.0 and Dodge 5.2).
The rubber grip stuff on the AA filter also screams Fram, since they use the same thing. I've not seen Purolator, or Purolator clones, like ProLine, with that feature.

Hmm-sounds good to me! I still have a scar on my forearm from 7 years ago on my `99 Ranger (3.0 ) from the exhaust manifold.
