OIL HPL BRAYCO MICRONIC 756

Castrol Brayco™ Micronic 756 is a red, low-viscosity, mineral-based hydraulic fluid, classified as ISO Grade 15, intended for use in aircraft, missiles and ammunition.
It is a blend of highly refined and carefully selected base oils, combined with suitable additives, resulting in a product with exceptionally good viscosity-temperature characteristics, good anti-wear properties, low rubber swelling and excellent oxidation stability.
The use of a low-molecular-weight polymeric viscosity index improver provides stability compared with typical hydraulic fluids.”
