ADVANCED LUBRICANT FOR GAS TURBINE ENGINES

GENERAL INFORMATION:
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. ROYCO 560 far surpasses the performance of traditional Type II (Mil-PRF-23699) fluids by combining higher thermal-oxidative stability with lower carbon residue formation. This results in better engine performance and longer periods between MOH. In addition, this third generation oil, Royco 560, can be used in any older engine designed to run onMil-PRF-23699 type fluids so that even these engines can realize the same performance benefits. Indeed, it has been demonstrated that third generation fluids, like Royco 560, can offer significant advantages over traditional oils in terms of lubricant life, engine cleanliness, and reduced emissions.
