If you have been told your warranty is no longer valid because you used biodiesel, or that it will be voided if you use biodiesel at any point in the future, you have been given inaccurate information.

Using Blue Sun Fusion will not void your vehicle’s warranty. A manufacturer cannot legally void the warranty on a vehicle due to the fuel used in the engine unless they can prove that the fuel caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act. (15 U.S.C. 2302(C)).  If Fusion is ever proven to be the direct cause of failure to any OEM-warranted fuel system materials, Blue Sun will repair or replace the damaged material at no cost.
