Cheap crude oil prices after the Second World War meant that the blending of ethanol into regular gasoline was not commercially viable. However, in November 1975 in response to the first crude oil crisis, the Brazilian government created the National Alcohol Program, “Proalcool”. This programme enacted the obligatory blending of anhydrous ethanol with gasoline (hereafter referred as gasohol) for fuels used by ordinary cars, which enabled the sugarcane based ethanol industry to increase its producing capacities.
