My personal opinion is that it will cause absolutely no harm at all. There are no ingredients/additives in engine oil that will cause damage when mixed - the only negative is that additives may be diluted by adding a different oil....and a lot of additives are only snake-oil. Oil manufacturers will have you believe you cannot mix oils but offer no proof...only self-interest.
