You can make the switch to synthetic without any issues or problems at all. It used to be claimed if you made the switch it could cause other issues, but honestly, it's a myth. The synthetic oil will not hurt the engine and you can go a bit longer between oil changes. In fact most synthetic oils are good for 5k between oil changes.

This will not cause you any problems at all.
