It is a real revolution which is underway. Since Monday, April 3, the Federal Ministry of Finance has authorized the sale of tax-exempt rapeseed oil (directly from the producer) and the effective use of this oil as fuel in any vehicle: agricultural vehicles, trucks, buses, etc. simple cars ...
From today, nothing prevents you from going to fill up with rapeseed oil at a farmer equipped with a baler and to drive with this biofuel, much cheaper (as an indication, it is about 70 cents a liter, against 1,1 euros for a liter of diesel). Nothing prevents you from refueling, but you should know that very few diesel vehicles today are able to run on rapeseed without technical modification.
