I've used several different stratgies when converting newly acquired equipment to Synthetic oil. Not everyone will want to just dive right in with extended oil changes. On a high milage vehicle I've used flush and AMSOIL XL before fully cutting over to Signature Series and Ea filters. Of course, you can just change the oil too. You don't have to do anything special. Synthetic oils won't cause any problems that weren't already there.
AMSOIL's recommended Signature Series service life is 12 months, 700 hours or 15,000 miles in severe service. Up to 25,000 miles in non-severe service. Jumping right in with Signature Series and pulling a sample after about 9 months will tell how your oil is holding up and you can make the desision to change it soon or continue based on results. Oil analysis also includes wear metals and contaminents and provides some information of what all the data means.
Since I'm already using AMSOIL Signature Series in several vehicles, starting any newly acquired vehicles on Signature Series simplifies the material inventory. And of course, I want to use the very best in my own vehicles.

AMSOIL’s OE line of oil is a great product for those looking to convert to synthetic oils but not ready to extend the drain intervals. It’s also a great way for those ready to switch to a once a year oil change, but are looking for a different season to change the oil in. When I first switched my F150 to AMSOIL it was early March with temps below zero. Not looking for a repeat date and temp a year later, I installed OE which shifted my annual oil change to late summer, starting an annual oil change interval with Signature Series oil and EA filter.
