Hi all I was just wondering how offten you guys change your synthic oil? I was figuring every 500 miles is this to long to go? I changed the regular oil at 100 miles 300 miles and at 600 I put in synthic and changed that at 1000 now I was planning on every 500, what's yor thoughts?

 

My dealer says the synthic is good for double the miles of regular oil. So I'm changing every 600 miles now. The literature says that is good for double and at the price it should be.
