Lubricant Selection In North America; Lubricant Requirements; Synthetic Oil - Detroit Diesel 60 Series Owner's Manual

LUBRICANT SELECTION IN
NORTH AMERICA
The selection of the proper lubricating
oil is important to achieve the long and
trouble-free service which Detroit Diesel
engines are designed to provide. The proper
lubricating oil for all Detroit Diesel engines is
selected based on SAE viscosity grade and
API (American Petroleum Institute) service
designation. Only oils licensed to display the
American Petroleum Institute (API) symbol
shown should be used.
SAE Viscosity Grade: 15W-40
API Classification: CH-4–CJ-4
HT/HS Viscosity: 3.7 cP minimum
API Lubricant Service Mark
OIL DRAIN INTERVALS
During use, engine lubricating oil undergoes
deterioration from combustion byproducts
and contamination by the engine. In addition,
certain components in a lubricant additive
package are designed to deplete with use. For
these reasons, regardless of the oil formulation,
regular oil drain intervals are required.
Fitzgerald Glider Kits recommends first initial oil
change at 5,000 to 7,000 miles to remove break-
in metals and rebuild contaminates. Oil should be
changed every 15,000 miles thereafter.
LUBRICANT
REQUIREMENTS
Lubricants meeting these criteria have
provided maximum engine life when used in
conjunction with specified oil drain and filter
maintenance schedules.
The preferred lubricating oil is
Shell Rotella SAE 15W-40 (CJ-4).

SYNTHETIC OIL

Synthetic oils may be used in Detroit Diesel
engines, provided they are approved by a
Power Guard Oil Specification. The use of
synthetic oil does not necessarily ensure
the extension of the recommended oil drain
interval beyond its limits.
