Oil level checking - the old fashioned way
Nothing like taking something that used to be simple and making it unduly complex. Instead of having a "min" and "max" marking on the dipstick, it actually is graduated in 1mm increments. Why you ask?
Well, you use the dipstick in connection with service procedure BF18.00-P-1000-03l (Oil level check for 113.990 engine). The reading you take of the oil level is then compared to the chart provided, and depending on your measurement you will either need to add or extract oil. Or get lucky and require no action be taken.
Here are the vital stats:
dipstick reading of 167mm - 169mm = Oil level correct
dipstick reading of 129mm - 165mm = Oil level too low
dipstick reading of 171mm 179mm = Oil level too high
The procedure is silent as to the outcome of either a 166mm or 170mm reading. Perhaps it's within the margin of error for the oil level being correct.
Once you know the actual reading (mine was 155mm after I changed the oil and deliberately didn't pour the entire contents of the 9th quart), you can refer to the chart to determine how many liters (in tenths of a liter) is needed to make the oil level correct. My car requires 0.8 liters to bring it up to the "correct" range, so my next purchase is a measuring cup that is calibrated in tenths of liters.
The only part of this that concerns me is that even being down .8 liters, my dash oil level check display states the level is okay. Anyway, I plan to monitor my engine oil level using the precision of the calibrated dipstick, and will now view the dash oil display for what it is - the equivalent of a warning light or "idiot" light that lacks precision but will probably warn you before the oil level becomes catastrophically low.




Have not had any warning lights on this though.
So guess I have the oil changed soon anyways and will wait until then.
But it's the correct tool for measuring oil levels in our AMG's. The "measuring tool" as MB calls it is 33.5 inches in length. Remove the factory red plug ( see first pic) and insert MB factory measuring tool down oil tube. You cannot close your hood when using it. If you look at my second pic that is as fare as it goes in. The oil fill for our motors is between 137mm and 168mm for a perfect fill. That info was given to me by a MB factory engineer at MB headquarters in Montvale, NJ during AMGfest this year. I go by his words.
