I agree with those that are advising you to stay with Dino.

Just change your oil frequently, and change it hot.

I use a Mercedes technician that has received rave reviews from members on this site. He has worked at Mercedes dealers in Europe, South Africa, South American, and Beverly Hills for almost 35 years, and has owned his own shop for the last 5 years.

He advised me to not use synthetic because in his opinion it wouldn't make a difference. He has rebuilt thousands of engines over his lifetime, and I repeat thousands of engines, and not one engine breakdown was caused by the failure of the oil.
