1997 E320 oil change to synthetic BAD?
My father has a '97 E320 with 110k that has always had dino oil. Today he had a reputable Indy shop change his oil. Long story, but the short of it is he thinks they may have used Syn instead of dino (yes, the work order says dino, but as I said, long story ...). As he understands it, <97s need to use dino only.
1. So, does MB say dino only in 1997 E320s? And, if so, why?
2. What issues/problems from changing to synthetic?
"Search"ing the forum, too ...
