Fuel Filter Plugging

  • Due to biodiesel’s solvency, it can clean fuel systems and deposit debris on filters and lead to premature plugging immediately after switching to biodiesel.

  • If running with biodiesel blends higher than 5%, fuel filters should be changed at ½ the recommended service intervals published in the engine owner’s manual. This is due to accelerated filter plugging from glycerides.

  • Fuel filter replacement is not to be covered under Detroit Diesel warranty. Detroit Diesel recommends using genuine Detroit Diesel fuel filters.

  • Secondary fuel system hardware failure attributable to premature fuel filter plugging with biodiesel blends is not covered under Detroit Diesel warranty.
