Depends what oil you have already as you can't mix grades.

You need to make sure you are not running 5w30 first and if so you need same grade any brand.

You can mix grades but not types (i.e. synth/semi/mineral).

Any fully synthetic - 0w-30, 5w-30, 0w-40, 5w-40 - is fine for topping up ...

0w-30 (or 0w-40 if you thrash down Autobahns) for oil changes ...
