That's interesting, thanks for the links. Since they're using the same Bosch high-pressure pumps and injectors as everyone else I don't see any real reason for the restriction, except perhaps some conservatism in the specs. There's nothing about B20 that would bother any part of the engine or emissions systems once the fuel components are up to date. I suppose they may simply be running out old spec stock. Anyway, to your point, it is disappointing. Along with the whole defeat device thing.
