mixing oil brands?

[DomP182]

I'm due am oil change soon and I've got enough if I mix fuchs 5w 40 from opie and some unipart 5w 40. Except for the fuchs being a better oil is there any harm in doing this?

No, buy more of one or the other.

Be alright.

Both fully synthetic obviously, I didn't think it would matter. Any more opinions ?
