Can biodiesel be used in any vehicle?
Biodiesel may degrade certain types of rubber gaskets and hoses in vehicles that are not suitable for the use of biodiesel (mostly vehicles manufactured before 1992). The higher lubricity index of biodiesel compared to petrodiesel is an advantage and can increase life-time of fuel injectors. Biodiesel is a better solvent than petrodiesel and has been known to break down deposits of residues in the fuel lines of vehicles that have previously been run on petroleum. Fuel filters may become clogged with particulates if a quick transition to pure biodiesel is made, but biodiesel cleans the engine in the process. It is therefore recommended, to change the fuel filter 800 miles after switching to biodiesel.
