Oil change on an E63?




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.















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.

The dipstick never lies







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.




When I gravity-drained all three (both coolers and the main oilpan), definitely a full-on 9.5 quarts was replaced back into the engine.
It's really not any more effort to drain this secondary cooler than it is to do the main cooler. I would recommend having an extra green viton o-ring in your parts stock, for the secondary cooler line, and replacing this o-ring every second or third oil change.

Draining the usual cooler at the line gets a verified 1L extra out of the system.
Extraction leaves too much old oil in there for my liking, and I need the car up on QuickJacks anyway to service it...so if there's another easily accessible component to drain, I'm all for it.

I have used top-end extraction for the past 25+ years on every other MB engine I've owned -- M103, several M104s, M117s, M119, M116, etc. Works fine for those applications, but the M156 is a totally different situation.
