Depending on the year the car it's rated for a max of 5%-7% bio diesel content. Believe one of the main issues is engine oil dilution. Of course this can be counter acted with more frequent oil changes But with sensitive High Pressure Fuel Pumps (HPFP) and very expensive injectors, need to be brave to venture into B100. I'm sure your warrenty would be voided if any engine related failure occured while running 100% bio.
