I just had my 92 500 seviced at MB and asked for synthetic, they installed Mobil One. I also went to another MB dealership owned by the same corporation, and when I got it back I noticed that it stated Pennzoil synthetic. This was on my 01 320E, when I got my customer service satisfaction survey I posted the question why? I immediately got an e-mail from the service manager, stating it met MBs standards. I further inquired, why previously they installed Mobil One, and was told that under the extended service plan they were required to install Mobil One since they had a marketing relationship with MB.
I was further advised that if I wanted Mobil One, it would be additional cost to their advertised Synthetic/Fleece filter oil change. I researched my records, and indeed the last 3 changes were with Pennzoil, charging the same price as Mobil One. I think they get it cheaper, and once out of warranty....they dont care.
