2022 540i MSport
I've logged about 5600 miles on my F10 535i. I took it in once for service at 2600 miles and at that time, the oil level indicator had dropped one "tick", 1/4 quart low. They must have topped it off because the next day when I checked the level, it read full again. So I've been keeping an eye on it every few days and about a month ago it dropped 1/4 quart again, which I figured was no big deal. OK, so yesterday I check it on the way to work and it had dropped to 1/2 qt. low since the day before. OK, so it seems to be using oil at a fairly low and consistent rate. So later on the way home I check it and what (?), it reads full! My trip home is 34 miles and I checked a few more times. It went back down to 1/4 low and stayed there the rest of the way. Has anyone else noticed this type of fluctuation? I'm wondering if the wide temperature range on some of these spring days is enough to push it up or down 1/4 quart if the level is right "on the edge" of going to the next level. Hopefully I don't have a bad oil sensor, I'll keep an eye on it.
