The risk of problems occurring in the engine increases as the level of biodiesel blend increases.
The following must be considered when using biodiesel blends up to
B20:
Expect a 2 percent reduction in power and a 3 percent reduction in fuel economy when using
B20
Cold weather flow degradation
Stability and storage issues (moisture absorption, oxidation, microbial growth)
Possible filter restriction and plugging (usually a problem when first switching to biodiesel on used engines)
Possible fuel leakage through seals and hoses
Possible reduction of service life of engine components
In addition to those factors listed above, the following must also be considered when using biodiesel blends above
B20:
Expect up to a 12 percent reduction in power and an 18 percent reduction in fuel economy when using B100
Possible coking and/or blocked injector nozzles, resulting in power loss and engine misfire if John Deere-approved fuel conditioners containing detergent/dispersant additives are not used
