CaddaBling Posted July 21, 2005 Report Share Posted July 21, 2005 Hey guys, I just purchased my Seville (2001) It has 57000 miles on it. The place I bought it from just changed the oil on it for me before I took it home. All my cars I own presently and previously, I use Mobil 1 synthetic in. I would like to use it in the Seville, but the next oil change will be at 60000 miles. Is that too late for me to start using synthetic? I have no idea what oil the previous owner used. He was elderly, and probably used the conventional 5w30. I do live in Florida and the temperature gets warm. Even on my Trans Am I still change the synthetic oil at every 3000 miles. What do you all think? Can I use Synthetic without any problems? Thanks! Take care Mike Link to comment Share on other sites More sharing options...
