ENGINE BREAK-IN INFORMATION

MIL-C-6529 Type II Multiviscosity 20W-50 Corrosion-Preven-
tative Oil is installed in the engine at the factory. It is recom-
mended that this oil be removed and the oil filter changed at 20
hours of engine operation or no later than 25 hours. If addi-
tional oil is needed during the first 25 hours of operation, use
an approved straight mineral oil per MIL-L-6082. If oil con-
sumption has not stabilized by this time, the engine should be
drained and refilled with MIL-L-6082 Mineral Oil. This oil
should be used until oil consumption stabilizes; usually a total
of approximately 50 hours. After oil consumption has stabi-
lized, MIL-L-22851 Ashless Dispersant Oil should be used.
Oils must meet the requirements of the latest revision of Tele-
dyne Continental Motors Corporation Specification MHS-24B
or current applicable Teledyne Continental Service Bulletin.
Refer to Section 8, HANDLING, SERVICING and MAINTE-
NANCE, for a list of approved oils.
