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!

APPROVEDÂ ENGINEÂ OILS

FOR VEHICLES WITHOUT FLEXIBLE SERVICE SYSTEM (FSS OR FSS PLUS) U.S. VEHICLES MODEL YEAR 1997 AND EARLIER

IMPORTANT: Engine oils are labeled on the container with various ACEA (Association des Constructeurs Europeens d'Automobiles) and/or API (American Petroleum Institute)
designations of quality. Mercedes Benz requires the use of MB approved engine oils listed in the Mercedes Benz oil specification sheet 229.3 or 229.5. If a MB
approved or ACEA quality engine oil is not available,  then an API quality engine oil meeting the below listed API classification can be used. Only engine oils
(including synthetic) with any of the following classification grades,  or combinations thereof,  are approved. Always refer to the viscosity chart (VISCOSITY
GRADES FOR MOTOR OILS) for the proper viscosity grade based on ambient temperature.

NOTE: This chart supersedes ALL previously published viscosity charts. For additional information,  please refer to the Operator's Manual.

U.S. VEHICLES MODEL YEAR 1997 AND EARLIER ENGINE OILS
Engine MBÂ Sheet APIÂ Classification(1) ACEAÂ Classification(1)
Gasoline 229.3 SJ A3
229.5 SL B3
Diesel 229.3 CF 4 B2
229.5 CG 4 B3
B4
(1) Only if MB sheet 229.3 or 229.5 is not available
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.
