These were, firstly, the requirement that distributors sell several petroleum products, ensuring that the proportion of sales for each product reflected that of national consumption. This meant, for example, that a distributor would have been required to distribute both fuel oil and gas oil, and to do so in fixed proportions.
Un distributeur aurait ainsi eu, par exemple, l'obligation de distribuer à la fois du fuel oil et du gasoil et ceci dans des proportions fixes.
