Hello all,
I've been reading this site for years, and finally decided to register. Attached is the latest report on my S55. I've owned it since new, did the initial 1250 mile oil change (which regrettably I did not get an oil sample from) and then changed it again 5000 miles later and most recently, 3500 miles. BMW 0w-30 has been used until now, and as you can see by the report, it's not doing well. The high aluminum worries me about the long term longevity of this engine, so I'm hoping smarter people here who have experience with the S55 can chime in and tell me if I'm right to be worried.
Thanks again,
Danny
