wrong!!!you can do whatever you want skids72, but that statrment is not true. new cars come with it in them every day. the hi doller ones anyway. .
Here are a couple of web-sites from oil manufactuers and what they say about using synthetic oil on a new engine.www.redlineoil.com check out what they say in their 4th paragraph.Also www.coximport.com They have a nice section in the 6th. paragraph.Also notice they recommend a long break-in for "hard piston rings"These are just a couple of oil companies that don't recommend using their own synthetic oil for break-in.
