Does BioDiesel require vehicle conversion?
No conversion is required to use BioDiesel, however early vehicles made before the mid 1990’s may have natural rubber fuel lines. If they do you might need replace them with metal or modern Viton lined synthetic fuel lines to prevent deterioration of the rubber parts (BioDiesel can soften rubber). If you have questions, consult with your mechanic. Burning BioDiesel in the winter depending on where you live may require a warmed secondary fuel tank to prevent geling since it will gel at between 40F and 20F depending on the base oil used.
