Checking C63 Engine Oil Level
I have checked my C63 engine oil as per the manual (10 minutes off after being at operating temperature). Everything is fine. Oil at max level.
If I check the next morning after it has been sitting all night, the engine oil level at the dipstick shows very low (add 2 quarts), right at the low cutoff.
Which is right? I don't want to overfill. Is it possible that when at temperature Mobil1 0w-40 expands that much?

If it is low, the car should send you a message saying something along the lines of "Check oil next time you put gas in car." Can't remember what it said exactly when I needed to add some.

So I guess the flipside to that is... how do I know the car isn't overfilled ... if it shows overfilled via the dipstick at operating temp, but shows max fill after it has sat overnight?

I always check mine in the morning after sitting overnight. Mine is at the bottom of the top red tab as I just did an oil change. Maybe I will check mine after it has reached operating temperature to see what it reads.

There's also a message for overfill, so don't panic.
The oil is a lot thicker in the morning and will take a lot longer to coat the dipstick. Make sure you leave it in the tube for at least 10 seconds after cleaning it. You might be getting a false low on the cold oil.

The car is difficult to get consistent readings from
Usually takes a few tries to get repeatable results
Mine reads the same when hot or cold
My manual says to check 5 minutes after shutdown
Reads the same in the morning when cold
More oil drains raising level
But cool oil has decreased density ~10%
Level constant
Leave the dipstick in 5 seconds
I leave it in longer and give it a wiggle when fully seated
This seems to help repeatability

This. I actually leave the dipstick in for 30 secs. A quick in-and-out just doesn't seem to result in an accurate and repeatable reading on this engine.
