2). During and after weekly maintenance run, check o ver
entire engine for signs of oil leaks. Repair immediately
if found or call your authorized DDC Distributor/Dealer
for service.
NOTE:
If oil is observed coming from the air box drain
tubes while running, review maintenance proce-
dure on page 19.
Yearly
Stationary diesel engines collect condensation in the engine
oil pan while at rest. When in use, lubricating oil undergoes
deterioration from combustion by-products and contamina-
tion. For these reasons, regardless of the appearance of the
oil, change oil and filter(s) annually.

CAUTION:
Use only recommended lube oil and oil f il-
ters. Internal engine damage and/or excessive wear could
occur using unauthorized materials.
LUBRICATING OIL ANALYSIS
Oil Analysis kits are available through the DDC Distributor
Network for efficient monitoring of the lubricating oil in a
DDFP engine. Refer to Parts Information Section 6 to order.
Oil Analysis consists of a series of laboratory tests conduct-
ed on the engines lubricant. Some tests sho w the condition
of the engine and others show the condition of the lubricant.
