Like said above, you can switch Full Syn oil without issue. But its best to try and religious with whatever brand of oil you get. You don't have to, but it takes the guess work out of what you are using and easier to explain to somone else might have questions about the type and brand of oil you use

I personally am stuck Mobil 1 Full Syn 10w30 myself. And K&N Oversize Oil filters to allow me a full 5qts of oil
