ROYCO 560 has been developed for the increased demands of the latest technological developments in gas turbine engines. With the advent of higher bypass ratio engines, higher thrust output, and consequently higher engine operating temperatures and pressures, this fluid has demonstrated a remarkable savings in lower maintenance costs and down time. Properties SpecificationsROYCO 560 has been approved for use in most aviation gas turbine engines requiring Mil-PRF-23699 approved fluids. In addition, ROYCO 560 is approved for use in industrial gas turbines manufactured by the Solar Division of Caterpillar, General Electric, Pratt & Whitney, Allison, Rolls Royce, and most others. Specific engine approval information may be obtained on request. ROYCO 560 is qualified to MIL-SPEC: MIL-PRF- 23699F Class HTS.
