Do you add engine oil between service interval?

If yes, how often? My friend is adding a quart at 4k miles, is there anyone who is adding more often?

What year, engine and mileage? Is the car telling him to add oil? I know the I-6 doesn’t have a dipstick, I don’t know if the V8 does or not.

Also, regardless of what it says in the manual, cars that aren’t driven very hard or abused shouldn’t require oil between oil changes in my opinion. If he’s adding a quart every few thousand miles, something is wrong.

After 12 months and 7k miles in my 2022 S500 I did not have to add oil but the dssh readout went from mid level to min.

As the new engine is breaking in its normal for it to consume some extra quarts as the rings seat ... and the manual will tell you how much is normal for you 223 engine (6 or 8) and how often
