You can mix any synthetic with any other synthetic and it's no issue, same with regular and regular. There is a debate on whether one can mix synthetic and regular oil. My personal research concludes it's no big deal to but there are some who will fight to the death on not being able to mix the two; or even go back to regular if you have used synthetic.
