How does using biodiesel fuel affect emissions certification?
John Deere engines are certified to meet emissions standards with the prescribed EPA and EU registered fuels. Engines operating on biodiesel blends above B20 may not fully comply with all applicable emissions regulations. It is the customer’s responsibility to use the fuel that these regulations require and that the engine manufacturer recommends. In addition, it is also the customer’s responsibility to obtain any local, regional or national exemptions required for the use of biodiesel in any emissions-certified John Deere engine.
