In connection with the introduction of Euro 5 in 2009, the sulphur content of diesel fuel for trucks and buses in the EU will be limited to a maximum of 10 ppm (parts per million). The availability of lowsulphur fuel is gradually increasing within the EU, with the implementation of Euro 4 making it possible to fill up with lowsulphur diesel at most filling stations in the EU countries.

The Volvo Group’s diesel engines with SCR technology are not vulnerable to temporary variations in the fuel’s sulphur content, but to ensure longterm low emissions and proper functioning, lowsulphur fuel should preferably always be used.
