Non-corrosive and high stability mineral oil Mineral oil is used on the R1 as it’s hydrophobic and does not absorb moisture from the environment. This means that there are no wet or dry boiling temperatures to worry about, the boiling point stays constant and never drops, resulting in braking force to be more consistent and linear.
