so i went by my mazda dealership yesterday to pick up my touch up paint from where the salesman nicked my sideskirt. he looked at my car and made a comment about my mileage and said bout time for an oil change. i said yeah im gonna do it myself instead of giving yall 30 bucks. he asked me what i was gonna use, so i told him mobil one. he said that these turbo cars do not like synthetic oil at all!!!! any truth to that?????
