The inventor of the diesel engine, Rudolf Diesel, used peanut oil-based biodiesel to power the first diesel engine more than a hundred years ago. Biodiesel has good lubricating properties, which keeps the engine running smoothly. In addition, biodiesel is extremely low in sulfur. This is good for the environment, because fossil diesel must first be desulphurised before it can be used as fuel.
The diesel that you fill up at the pump in Europe does not present any problems for your car engine. In Europe, almost all vehicles produced after the year 2000 are suitable for B7. Cars that are not suitable for B7 are older cars or vintage cars. An overview of the diesel cars in Europe that are suitable for B7 can be found on the website of the European Automobile Manufacturers Association. Also website of the Bicycle and Automobile Industry Association (RAI) contains information about biodiesel.
Many passenger cars can already handle B30 mixtures. Trucks with modern engines can already run on higher blend biodiesel. These higher mixtures are not sold at the pump, but usually to companies that have their own pump for their fleet of trucks or vans, for example.
