My XC90 D5 handbook says max 5% blend only.
VW say no biodiesel unless you order a car specificly for biodeisel use.
Merc say OK for the CDI 220 and 270 but NO for the CDI 320
Elsbett the German biodiesl conversion company, who also build engines for using biodeisel, who have the most experience say SOV is only suitable for journeys of longer than 20 miles. You need to change your oil every 5000 miles.
I've seen a report on the New Scientist web site that says a German lab has found the biodeisel emissions to be highly carcenogenic. That's not a suprise really as all other burnt organic matter seems to be. i.e. cigarette smoke bonfire smoke and burnt toast.
