I currently have 19,000 miles on my truck. Im due for an oil change around 20,000 miles. Im running Amsoil sythethic now, but want to go back to dyno oil. I know that after running dyno oil for many years and then going to a synthetic will cause problems. But what about going from a synthetic to dyno?

 

Why the switch?
You can switch back and forth without issue.

 

Im running the same oil in my truck, why would you want to switch?
