synthetic to regular 850

Yes it's safe to go back and forth between syn and dino oils b/c they are compatible with each other. BUT why would you do that? I use syn oil only and stretch out the oil change interval to at least 5,000 miles (sometimes longer if all the mileage is highway). This helps to offset the cost factor if you are concerned about the additional expense for syn. In either case use syn if you have a turbo. The engine will love you for that.
