I don't have the specs for the AMG engine but the specs for the 3.2 motor of the NA is 8.5 US Quarters with the oil filter which holds about a half a quart) or 8 litres (so 7.93 is pretty close to 8). Keep in mind, this is with a filter change. When I change my oil I change the filter. When I put 8.5 quarts in it is spot on with the dip stick and I have Never got a "HI" indicator with this amount. I have however gotten a "LO" when I've put in 8 or less. What ever you guys are comfortable with, but from my experience, reading the owners manual and checking sources at mercedes, the book is accurate. Maybe the qualifier is with a filter change. However, I don't know why anyone would change the oil and not change the filter. Here's to all our engines lasting 300K miles.
