Precision Blend System Question

[dubber]

Yes but it will show that oil pump is putting oil into the system if the level is going down and gives you piece of mind that oil is being added automatically.

If you are that concerned about exactly how much, then follow the service manual procedure and measure it

Agreed that marking the level let's you know it is going down but that isn't what you first suggested

I am not worried about exactly how much - my first questions were more about understanding the internal workings of the precision blend system to see if there is more to it than the pump
