Under warranty it would be best to go by manufacture establish requirements.I have given my opinion so often I sometimes feel like a broken record. (I suppose I would still be dating myself were I to say "endless loop".)
Around $30 for an analysis from a reputable lab is much cheaper than an hydraulic oil change and is pretty cheap peace of mind that you are not harming the system.
