Biodiesel is actually better for your engine than petroleum diesel. As little as 1% biodiesel added to petro-diesel provides 65% greater lubricity. Biodiesel testing shows less engine wear, which extends engine life. The only problems associated with biodiesel center on biodiesel’s solvent properties and cold weather gelling. Engines built before 1993 are likely to have fuel lines and o-rings that can degrade over time. Early replacement of these items insures trouble free operation. Biodiesel’s solvent properties also loosen deposits left by petro-diesel, which may clog fuel filters. While many theories exist on when to change filters, my experience has show this varies with the type, age and condition of each vehicle. What seems to be agreed upon by most biodiesel users is to replace filters after the first one or two tanks full of B100 then pay close attention to performance. Whenever you experience a loss of power, check fuel filters for debris being dislodged from the impurities that have accumulated in your fuel tank over the years. In my experience this is the problem about 99% of the time.
I recommend everyone learn how to change filters (it’s pretty simple) and keep extra filters in the vehicle, especially at first. Once all this grime has been removed from your fuel system you’ll experience a better running, longer lasting engine. In a few extreme cases, we have pulled the fuel tank and cleaned it thoroughly to greatly reduce fuel filter replacement.
In the case of B20 and lower blends, fuel tank impurities cycle through fuel filters much slower and pose less urgency concerning filter replacement.
