Experiencing weird oil levels

[Jacob_24]

When I drain my oil, I use a home depot bucket which would get full all the way up and leave about 2" of free space but lately when I drain oil it gets only 3/4 full in the bucket and then when filling her up with fresh oil I would be left with at least a 1/4 of oil in the jug and dip stick would read MAX !

My question is, why isn't all of my oil being drained? I make sure I drive and get the oil up to running temps right before I do my oil change.

I use motorcraft 5qt oil jugs and before it would take exactly 3 full one and still be below max on dipstick.

Thanks guys
Jacob

You sound like you've done it before and haven't had any problems, but my guess would be that you're either not removing the oil filter first (and leaving it alone until you've drained the oil from the oil pan) OR the valve in the oil filter housing is stuck closed. Just a theory.

I do unscrew the filter prior to draining the oil. Can I visually see if it's stuck close?

One way is to remove the filter, then look in the housing for any remaining oil. It should be empty.
