FUELS AND LUBRICANTS
DIESEL ENGINE
In temperatures above 32° F (0° C), use number 2 diesel fuel in your Case
diesel engine. See NOTE. When you operate in temperatures below 32° F
(O°C), use number 1 diesel fuel.
NOTE:
If the temperature lowers to the "Cloud Point" of the diesel fuel,
wax particles will be in the fuel. These wax particles will cause a restriction of
the fuel filters. Then, the engine power will decrease. See your fuel dealer for
more information.
Diesel Fuel Specifications
Different manufacturers can have diesel fuels of different specifications.
All diesel fuel used in Case diesel engines must be the same quality as specifi-
cation

Fuel Storage
If you keep fuel in storage for a period of time, you can get foreign material
orwater in the fuel storage tank. Manyengine problems are caused by water in
the fuel.
Keep the fuel storage tank outside and keep the fuel as cool as possible.
Remove water from the storage container at regular periods of time.
