    Oil change with/without oil filter change is 4.4/4.1 US quart, so yeah, taking the oil filter housing should extract 0.3 US quart. Judging from the dipstick that would get it pretty close to the top mark.

    What you meant, if I pull the Filter Housing completely off, It wouldn't drain all the oil from oil sump?

    I've never done that, but I've read that here many times, I believe that's the case. Basically that the sump level is somewhat lower.

    You could hedge your bets: unscrew the housing most of the way but not completely, and just cock it a bit. I believe you'll see a bit over a cup come out, then it'll subside.

    AND it probably says that on the OTHER side of the stick.
    Regardless I think he is wasting his time and is worrying unnecessarily.

    After I posted, I figured out that the pointy end of the dipstick is up and the handle is down, and that’s the full marker showing; so it’s slightly overfilled. That was not clear in the early photos.

    As I was running my errands this morning, my oil change required message popped up. 5k and no oil usage. YaY just what I wanted to do when it’s 95 degrees and 75% humidity.

    it comes up every 5k, but you only have to change it at 10.

    I know. But I want at least one more oil analysis before I start going longer on the changes.

    A fella in here posted last week that he’s only changed crankcase oil 3 times in 100,000 miles driven.
