I'm assuming you're asking about the engine oil? It's at the bottom of the oil pan. The drain bolt is facing the passenger side front wheel.Where is the drain oil plug on a 2003 Mercedes 350 ml?
You may need to remove the belly pan to get to it. Mercedes dealers vacuum the oil out the dipstick tube. You can get an inexpensive pump to do this, it's really a much neater way to accomplish the job.
Right underneath the vehicle the Oil Pan.
