Please, I was told that I CANNOT use synthetic oil in my mercedes 190E 2.3. Is that true?
If I cannot use it, why is it?
If yes, I can use it, what specs should be?
Thanks!

this is a merecedes bulletin as of 2007 so it's safe to use synthetic as long as the api rating is ok which it will be if you buy synthetic. Api rating is sj for gas adn cg for diesel.
