Guys, You have to remember how many cars come from the factory with syn already in the motor, ALOT (i.e. Corvette, Porsche, Ferrari etc). They don't break a cars engine in at the factory with non-syn and then switch to syn before it rolls out. The old saying that you don't want to break an engine in with syn is just that.."old". Many people used to believe that a syn was too slippery and would not allow an engines new parts to break in properly. A total myth. I would have put syn in it when I picked it up from the dealer with 190mi on it (drove it from Tucson to Phoenix)if I could have. What you want to do is drain the oil with a few hundred miles on it and replace it. The factory oil has all the metal particles floating around from break in and you want to get rid of that and the filter.
Once you have changed the oil and put a very good filter on it (Purolator Pure One) you can run it for about 7500mi before your next change.
I use 5 qts of Penzoil Platinum 5w30 and a pure One filter. I've been doing alot of oil research over the past few years and IMHO you want to stay away from purple synthetics that make false claims of horsepower gains just by changing the oil.
Feel free to ask any questions
