NOTICE:
If the oil level is constantly above normal
and excess lube oil has not been added
to the crankcase, consult with an autho-
rized Detroit Diesel service outlet for the
cause. Fuel or coolant dilution of lube oil
can result in serious engine damage.
Before adding lubricating oil, refer to
How to Select Lubricating Oil in the
How To section of this guide. Change
lubricating oil and filters at the intervals
listed in Table 7 when using fuel with a
sulfur content of less than 0.5 mass
percent. When using fuel with a higher
sulfur content, refer to When to
Change Oil in the How To section.

Item 2 — Fuel and Fuel Tank
Keep the fuel tank filled to reduce con-
densation. See Figure 13. Before adding
fuel, refer to How to Select Fuel Oil in
the How To section of this guide.
Figure 13. Keep Tank Filled to Reduce
Condensation
Refill the tank at the end of each
day's operation to prevent condensation
from contaminating
Condensation formed in a partially filled
tank promotes the growth of microor-
ganisms that can clog fuel filters and
restrict fuel flow. To prevent microbe
growth add a biocide to the fuel tank or
primary fuel supply. Follow manufactur-
er's usage, handling, and safety recom-
mendations.
Water accumulation can be controlled
by using additives containing methyl
carbitol or butyl cellusolve. Follow manu-
facturer's usage, handling, and safety
precautions.
Open the drain at the bottom of the
fuel tank every 30,000 miles or 48,000
km (300 hours for industrial applications)
to drain off any water and/or sediment.
Every 12 months or 120,000 miles
(192,000 km) (600 hours for industrial
applications) tighten all fuel tank mount-
27
the fuel.
