• Component Protection - specially developed additives form a protective layer on wear surfaces, reducing wear in hydraulic
pumps and other components. Cat BIO HYDO Advanced provides excellent corrosion protection to steel and bronze components,
even at high temperatures.

{A} The values shown here are typical values and should not be used as quality control parameters to either accept or reject
product. Specifications are subject to change without notice.
{B} Not recommended for use in Cat Hydraulic systems.
{C} High Viscosity Index oils containing viscosity modifier additives will become thinner during use, this will reduce the level of
protection.
