Oil measuring rod

Just for information: I have a Mondeo TDCi 2.0 85 kw. After the inspection, the oil was checked on the workshop site to see what level of oil I had to pay attention to. I had the impression that my measuring rod was wrong before. And look, apparently 1 litre of oil was filled up. Shown to the master who asked the journeyman: “No, there are exactly 6 liters in it.” Master: “Letting off in measuring can!” Were exactly 5.6 liters in, left in the oil filter. Until the “O-Ring-Knubble”, that is only the thin part for measuring, it shows me the exact maximum value of the oil filling. Shouldn’t you completely sink the measuring rod to the measurement? Master: “:-” He hadn’t experienced it yet. The measuring scale made of plastic was probably mounted too deep, of course I get such a defective product again. With oily greetings to all Ulli PS.: Look for a holiday of the other kind on my page -No advertising, promised!-
