Oil level does not change after topping off
Hi all, I'm wondering if anyone seen this before.
Car is warmed up after a normal city drive. Coolant 200f, oil 220f, transmission 160f. 1st check the oil is at the min mark. Added about 0.6L, the oil level did not move at all. The capacity between the min and max mark is only 1L. There is not way the oil mark staying at same spot after adding 0.6L. I took the measurement when engine was off.
Any thoughts?

Probably should had took the second measurement an hour or 30 minutes at least after filling but I think MB has a particular set of steps to check it with a dry sump, engine has a dry sump right?

Was the engine oil in the engine also cold, or just you mean the oil you added was cold? So you started the vehicle after adding the oil then you took the measurement? It might need some time to drain it back to the pan.

Will check again tomorrow. But no, M157 is not dry sump. Only requirement for checking oil level is coolant temp >= 80C from WIS

Engine was hot. The added 0.7L new oil was room temp. So after adding oil, I ran the engine for 30s, turned it off, then waited another 30s before taking the 2nd measurement.

As mentioned, run it up to operating temperature, then measure after letting it sit for 5 minutes. Make sure your are parked in the same exact spot, in the same suspension settings.
conceptually imagine adding that volume of fluid to an empty oil pan and how much it might actually raise considering the surface area. It won’t raise much, but it will raise a couple millimeters, ime.
next, I might ask, do you know the total volume of oil you are adding to your car, as well as the oil volume offset from your data sheet?

So theoretically for my M157 it should be 8.5L + 1.1L = 9.6L? I assume this 9.6L is the max capacity meaning 8.6L is the minimum line?

Theoretically yes but I suggest to keep adding and checking and not add all of it at once just on the safe side.
