Besides, the 1997 oil visc/temp chart I finally found for the C230 indicates that 10W-30 *is* acceptable to MB if outside temps don't go above 90 . . . which will (generally) be true during the blink-and-you'll-miss-it NO winter. Not to mention that back then it specified "SJ" oil, and here we are up to SL/SM. Oils have only gotten better, right?
