Lubricity Of Diesel Fuel; Handling And Storing Diesel Fuel - Worldwide Construction And Forestry Division 380GLC Operator's Manual

Lubricity of Diesel Fuel

Most diesel fuels manufactured in the United States,
Canada, and the European Union have adequate lubricity
to ensure proper operation and durability of fuel injection
system components. However, diesel fuels manufactured
in some areas of the world may lack the necessary lubricity.
IMPORTANT: Make sure the diesel fuel used
in your machine demonstrates good
lubricity characteristics.
Fuel lubricity should pass a maximum scar diameter of
0.52 mm as measured by ASTM D6079 or ISO 12156-1.
A maximum scar diameter of 0.45 mm is preferred.

Handling and Storing Diesel Fuel

CAUTION: Reduce the risk of fire. Handle fuel
carefully. DO NOT fill the fuel tank when engine
is running. DO NOT smoke while you fill the
fuel tank or service the fuel system.
Fill the fuel tank at the end of each day's operation to
prevent water condensation and freezing during cold
weather.
Keep all storage tanks as full as practical to minimize
condensation.
Ensure that all fuel tank caps and covers are installed
properly to prevent moisture from entering. Monitor water
content of the fuel regularly.
When using biodiesel fuel, the fuel filter may require more
frequent replacement due to premature plugging.
Maintenance—Machine
If fuel of low or unknown lubricity is used, add John Deere
Fuel-Protect Diesel Fuel Conditioner (or equivalent) at
the specified concentration.
Lubricity of BioDiesel Fuel
Fuel lubricity can improve significantly with BioDiesel
blends up to B20 (20% BioDiesel). Further increase in
lubricity is limited for BioDiesel blends greater than B20.
Check engine oil level daily prior to starting engine. A
rising oil level may indicate fuel dilution of the engine oil.
IMPORTANT: The fuel tank is vented through the
filler cap. If a new filler cap is required, always
replace it with an original vented cap.
When fuel is stored for an extended period or if there is
a slow turnover of fuel, add a fuel conditioner to stabilize
the fuel. Keeping the free water drained and treating the
bulk fuel storage tank quarterly with a maintenance dose
of a biocide will prevent microbial growth. Contact your
fuel supplier or John Deere dealer for recommendations.
