ok update for you.. Was able to check my relative's 16 CX-5, yup like I thought.. The day the oil change was done with 5 qts the level on the oil dipstick was 1/2 way between min and max. A couple days later (today) it was at the 2/3 full mark. So yes it's exactly what I was thinking I've experienced before with my Scion tC's engine, oil hiding out in the galleys, because I know the oil was fully drained.Agree. This is the most likely explanation.
Curious on what you find the level at in a few days.
So there's the answer, it's only oil hiding out in the galleys/etc. At least we have a simple explanation for it.
Also- adding the extra oil to get to the max fill line only adds to what's "hiding" and then you're over the full/max mark on the oil dipstick. I agree put 5 qts in and call it a day.. in case anything more is already in there, it won't cause it to be over filled.
