Why does Magura use Magura Royal Blood mineral oil and not DOT break fluid?
Unlike break fluid mineral oil does not age with time and therefore offers consistent performance over many years. Furthermore break fluid absorbs water over time, which leads to a loss of heat resistance and a reduction of the boiling point. This notably affects the performance of the brake. DOT brake fluid is also poisonous and corrosive. A small drop is enough to erode the finish on a bike or damage the skin. Mineral oil is in comparison much easier to handle and offers consistent performance over a long period of time.
