A1 Service interval

I just changed the oil on my 2010 GLK350 4Matic at 9100 miles on the oil and filter and sent a sample to Blackstone. They said it look great and still had some additives (3.7) and the 10K interval seems to be doing fine.
Send your oil in when you change it to establish a baseline. It's saves money and your engine to be sure. A $35 well spent.
