All engines not using common rail injection can be fuelled with B100 without modification, and performance will be the same as if using normal diesel.
All commonrail engines are approved for use with B20 and it is possible that greater concentrations can be used in the future.
Announced the use of B20 across its range of 400d and 1100D engines. The company said it has been working with a number of OEM customers to trial higher precentage blends and initial results point to trouble-free operation.
I wonder why commonrail is approved for b20 and not b100? I am guessing that once winter comes around and b100 gels up, they don't want to get stuck with warranty claims and negative media
