Regarding when to start using synthetic oil, I read on ROYAL PURPLES' web site that they recommend not using their oil until at least 2000 miles:
"Royal PurpleŽ currently offers many viscosity grades of API Licensed Motor Oils. (See the Royal PurpleŽ Motor Oil Product Page or visit the API Engine Oil Licensing and Certification Website for more information). To allow for proper breakin of the engine, Royal PurpleŽ recommends waiting until the manufacturer's first scheduled oil change or a minimum of 2,000 miles in new gasoline engines. Allow 8,000 to 10,000 miles before using Royal PurpleŽ in diesel engines."
Others say there is no difference and you can use synthetics from the start.
Which is it?
