APPLICATIONS:
ROYCO 808 is intended for use in the lubrication of aircraft gas turbine and industrial turboprop engines - especially those operating in extreme cold or hot environs. ROYCO 808 is also recommended for use in engines, which require start-up after extended periods of “cold soak” such as aircraft, APU's and railroad industrial snow removal equipment. ROYCO 808 may
also be used as a control fluid in stationary turbine applications.

APPROVALS:
ROYCO 808 meets all requirements and is qualified under MIL-SPEC: MIL-PRF-7808L Grade 3.

COMPATABILITY:
ROYCO 808 is not interchangeable with any other lubricating oils except those qualified under Mil- PRF-7808 or Mil-PRF-23699.
