Good seeing you yesterday!
That was the point; the fill level at the sump is engineered to be filled with that oil pumped up there doing its job.

Filling and then checking cold 24hrs later would provide for a false full reading; in addition to being a highly impractical method for checking the fill.

I enjoyed meeting you as well; your 77 was hands down the nicest condition car there on a age adjusted basis IMO and was cleaner than most on a non adjusted basis too.

I used to get very inconsistent readings on the 616 in my 307d.

On the 603 and AFAIK the 606 it takes two quarts to go from min to max.

Everyone says your supposed to keep it in the middle.

Other way around, hot oil expands.

your both wrong, best way to know you have the exact ammount of oil your engine uses is to fill it to the exact ammount it can take. FSM calls for a certain ammount, fill it to that point exactly (including oil filter housing) should be right on the dot.

Wrong again. There is no way to know exactly how much oil is still suspended in the engine, clinging to surfaces and in the oil cooler. Filling to the exact amount will usually be slightly overfull.

lol, i was joking just to throw something out there. You could get a digital dipstick that would accurately measure the level of the oil, the temperature of the oil and the viscosity and fill it to the exact ammount that way. theres some overkill lol. Hmmm...i just got an idea...

I have found with synthetic oil that you usualy need to wait a bit to get a good reading. It drains down so slow if you check it while say fueling up you will get a false low reading, by about 1/2 a quart on my car.

If you wait a few hours you'll find your engine makes oil.

Now see, I always thought that the MB engineers were probably smart enough to put the little notches in the right place.

Sometimes one has to be careful not to think too much!
