•
Possible reduction in water separator efficiency
•
Possible damage to paint if exposed to BioDiesel
•
Possible corrosion of fuel injection equipment
•
Possible elastomeric seal and gasket material
degradation (primarily an issue with older engines)
•
Possible high acid levels within fuel system
•
Because BioDiesel blends above B20 contain more
ash, using blends above B20 can result in more rapid
ash loading and require more frequent cleaning of the
Exhaust Filter (if present)
IMPORTANT: Raw pressed vegetable oils are
NOT acceptable for use as fuel in any
concentration in John Deere engines. Their
use could cause engine failure.
Testing Diesel Fuel
A fuel analysis program can help to monitor the quality
of diesel fuel. The fuel analysis can provide critical
data such as cetane number, fuel type, sulfur content,
water content, appearance, suitability for cold weather
operations, bacteria, cloud point, acid number, particulate
contamination, and whether the fuel meets specification.
Contact your John Deere dealer for more information on
diesel fuel analysis.
Fuel Filters
The importance of fuel filtration cannot be overemphasized
with modern fuel systems. The combination of increasingly
restrictive emission regulations and more efficient engines
requires fuel system to operate at much higher pressures.
Higher pressures can only be achieved using fuel injection
components with very close tolerances. These close
manufacturing tolerances have significantly reduced
capacities for debris and water.
John Deere brand fuel filters have been designed and
produced specifically for John Deere engines.
To protect the engine from debris and water, always
change engine fuel filters as specified in this manual.
