The British supermarket chain Morrison's sells B30 - petroleum diesel with 30 percent biodiesel blended into it - at 113 pump stations in their supermarkets in the United Kingdom. However, switching to B30 might not be advisable for some motorists, and there are still worries that the biofuel could void the car's warranty. Currently, only PSA engines, sold under the Citroën and Peugeot marques, explicitly allow drivers to fill up with B30 without voiding the warranty. 15 other brands - Audi
