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.
