Brazil: Fuels: Diesel and Gasoline

Brazil: Fuels: Diesel and Gasoline


As of 2013, S10 (10 ppm sulfur) diesel is available in major metropolitan areas and selected stations nationwide to fuel P7 trucks. As of 2014, S50 (50 ppm) gasoline is sold exclusively nationwide to fuel L6 light-duty vehicles. Brazil has also implemented ethanol and biodiesel standards that are described on the Brazil Biofuels Policy Page.

Brazilian fuel specifications are established by the National Agency of Petroleum, Natural Gas and Biofuels (ANP—Agência Nacional do Petróleo, Gás Natural e Biocombustíveis).


Since 2001, on-road diesel fuel quality has been differentiated by location, with key milestones as follows:

  • In December 2001, ANP Resolution 310/2001 defined the specifications for two types of on-road diesel fuel: Metropolitan and Countryside. Metropolitan diesel fuel was the only diesel fuel permitted for sale in select cities in Brazil (first to those cities with poor air quality then to cities with more than 200,000 inhabitants) and limited sulfur to 2,000 mg/kg (2,000 ppm). Countryside diesel fuel was intended for the other parts of the country and had a sulfur limit of 3,500 mg/kg (3,500 ppm).
  • In December 2005, ANP Resolution 12/2005 introduced a third type of diesel fuel, S500, which had a sulfur limit of 500 mg/kg (500 ppm). It replaced Metropolitan diesel fuel in select municipalities in Rio de Janeiro, São Paulo, Campinas, Baixada Santista, Sao Jose dos Campos, Belo Horizonte and Vale do Aço.
  • In July 2006, a new diesel fuel specification was introduced in ANP Resolution 15/2006, and replaced ANP Resolution 310/2001. The S500 diesel fuel was dropped but the sulfur limits of Metropolitan and Countryside diesel fuels were lowered to 500 and 2,000 mg/kg respectively. It also required the sulfur limits for Metropolitan and Countryside Diesel fuel to drop to 50 and 500 mg/kg to coincide with the introduction of exhaust emission standards equivalent to Euro IV in 2009. The goal of introducing S50 diesel in Metropolitan diesel was not achieved as planned for January 2009 due to technical problems at refineries and with the automotive industry.
  • In November 2008, CONAMA (National Council on the Environment) issued resolution 403/2008 which required ANP to develop a fuel standard to enable the introduction of diesel fuel with a 10 mg/kg maximum sulfur limit (S10) by 1 January 2012.
  • In December 2009, ANP Resolution 42/2009 replaced the Countryside and Metropolitan grades of diesel fuel defined in ANP Resolution 15/2006 with S50 (50 mg/kg sulfur), S500 (500 mg/kg sulfur) and S1800 (1800 mg/kg sulfur). It also required S50 to be sold exclusively in a number of metropolitan areas in the states of Pará, Ceará and Pernambuco; in bus fleets in the municipalities of Rio de Janeiro, São Paulo and Curtiba and in urban bus fleets in many cities in the states of Rio de Janeiro and São Paulo. Numerous other Brazilian cities were required to exclusively sell S500. S1800 could be used in other parts of the country but would be phased out by 1 January 2014 and replaced with S500.
  • In September 2010, ANP Resolution 33/2010 delayed the switch to S500 in some municipalities by up to 15 months.
  • In October 2011, a consultation was held to establish a new fuel standard that includes an S10 grade. The proposal would (1) require Type B (containing biodiesel) S50 in many municipalities that previously required S50, (2) replace S50 with S10 starting 1 January 2013 and (3) require numerous states and municipalities to switch from S1800 to S500.
  • On 1 January 2013, S50 diesel fuel was replaced by S10 diesel fuel in major metropolitan areas and in selected stations nationwide to fuel P-7 trucks.

Brazil achieved the total phaseout of leaded gasoline by 1991. Until the end of 2013, gasoline with up to 1000-ppm sulfur was sold in some areas of the country. As of January 1, 2014, S50 (50 ppm) gasoline is sold exclusively nationwide, to coincide with new emission standards for gasoline light-duty vehicles (L-6).

Alternatively, it is allowed to determine the cetane number calculated by the NBR 14,759 (ASTM D4737) for the diesel oils A and A S1800 S500, when the product contains no cetane improver additive, with a lower limit of 45. In case of non-compliance, the cetane number test should be performed. The producer and importer shall inform the Certificate of Quality where it is used cetane improver additive. Note that the cetane number does not reflect the quality of ignition of diesel containing biodiesel and / or cetane improver additive.

Brazil has a government-mandated ethanol blend in gasoline fuel, which ranges from 18 to 25 percent. There is also extensive use of higher ethanol blends, and very high market penetration of flex-fuel vehicles (as well as a legacy fleet of ethanol-only vehicles). In response to an ethanol shortage in early 2011, the government created new rules defining ethanol as a fuel (as opposed to an agriculture commodity), and thus authorized ANP to regulate and control its production and distribution.
