Will biodiesel clog the catalytic converter in a 2008 diesel truck?
Biodiesel emissions are much cleaner than emissions from
conventional diesel. Carbon dioxide is reduced by 90%, sulphur by
100%, carbon monoxide by 10-50%, and hydrocarbons by 10-50%. The
only emissions that increase are nitrous oxide emissions. However,
this is counteracted by your catalytic converter. So the answer is
no, boidiesel will not clog your catalytic converter.
