Brayco® 599 is a specially designed synthetic base, dark amber, rust preventative concentrate.
Brayco 599 is designed for use as an additive for turbine engines and helicopter transmissions which use MIL-PRF-23699F
lubricating oil. Brayco 599 should be added to the oil sump immediately after an oil change when the equipment is intended to be
placed in storage, especially in locations where high humidity and salt spray are present. The corrosion inhibited oil should be
capable of limited use, not to exceed 25 hours. Consult the engine manufacturer's manual to determine specific engine model
recommendations and/or limitations.
To receive full protection for extended equipment storage, Castrol recommends addition of Brayco 599 in concentrations between
10% and 15% by volume. Lower concentrations between 5% and 10%, may be suitable for some component storage applications
depending upon storage conditions and length of storage. Consult the engine manufacturer's maintenance manual or service
bulletin to determine specific engine model dilution ratio recommendations.
For use in MIL-PRF-23699F synthetic turbine oils at 10-15% volume addition for storage. Meets the requirements of General
Electric Aircraft Engine Group Specification D50TF6-S1.
