B100
B100
or other high-level biodiesel blends can be used in some engines
built since 1994 with biodiesel-compatible material for parts
such as hoses and gaskets. However, as biodiesel blend levels
increase significantly beyond B20, a number of concerns come
into play. Users must be aware of lower energy content per
gallon and potential issues with impact on engine warranties,
low-temperature gelling, solvency/cleaning effect if regular
diesel was previously used, and microbial contamination.
B100 use could also increase nitrogen oxides emissions, although
it greatly reduces other toxic emissions. All these issues
can be handled, but currently B100 use might be best for professional
fleets with maintenance departments prepared to deal with
this fuel.
