Many years ago, I found out something the hard way. I used the wrong size crush washer on the oil pan.
I had oil sprayed all in the engine belly pans. So having the right oil pan crush washer is critical.
Not to mention, I had to do another oil service. No that the oil was bad, but because I needed to replace the crush washer.

True proper oil change includes the main oil pan, the front oil cooler and the Passenger side oil cooler for an E63. All 3 of these will get you to the 9.5 qts refill.

So where is the drain plug located at, on the passenger side oil cooler? Because I don't remember every seeing one. But I do drain both the oil pan and the front oil cooler.

cCn we drain the passenger side cooler? I only drained the pan and front oil cooler. How much oil should be refilled if those are drained?

I've looked at countless photo of the passenger oil cooler, and I can't find a single photo the shows a drain plug. So I convinced that there isn't one. Proof me otherwise.

There is no drain plug on the passenger side oil cooler, only the front mounted cooler has a drain plug.

does anybody have a picture of the bumper not mounted? would it be that the passenger side cooler is higher than the front cooler so by default it will gravity drain through the front cooler?

Having done numerous oil changes; I gave this some thought and realized since the passenger side oil cooler doesn't have a drain.
It probably does drain by gravity back to the front oil cooler. As you do get a substantial amount of oil from it when drained.

Does anybody know how many mm the oil should be? E55 guys say that it is supposed to be 165 mm for their engine. Since the updated dipstick is useless I want to use the one that shows oil depth in mm.

Remember someone told me, that 165mm is about right for the E55. I'm certainly glad that the E63 came with a proper dipstick.
The dipstick never lies

BTW guys, in my post above about draining all three areas of the E63, I never said there is a drain *plug* for the cooler up under the right side of the bumper cover in front of the passenger wheel. There is an aluminum tube fitting into the cooler and a single screw holding the fitting into the cooler. Remove the screw, pull out the aluminum fitting (there is a rubber O-ring on the fitting) and voila, another stream of oil will drain out. The oil pan and front center cooler have drain plugs. Next time I do an oil change, I'll take a pic or two.

Thanks for sharing. Next time I change my oil I will use an extractor pump. I called my dealer and they said that they were actually using extractor and recommended it. So far I've been draining oil from two places. Curios to compare.

Everyone is entitled to drain their oil their way. And you can never be sure that you got 100% of the oil drained. But I'm old school, and draining the oil by letting gravity do the work, is IMHO probably the best way.
The oil extraction method, doesn't get all of the oil out. Only the oil that is in the pan. You still have oil in both the front and right oil coolers, and by draining the front cooler you remove most of the oil in the right oil cooler as well.

But its your call, and your AMG. Do it your way.....
