Petrol and diesel prices in Brazil (BRL)
The petrol (gasoline) price in Brazil is 6.55 BRL per litre, and diesel costs 6.85 BRL per litre, as published on October 6, 2026. These are official retail pump prices, not model estimates.
At the official exchange rate of 5 BRL per US dollar, a litre of petrol in Brazil is worth about $1.311 and a litre of diesel about $1.371.
How fuel prices are set in Brazil
Most countries in ETCurrency's coverage — Brazil included — import refined petrol and diesel or the crude they are made from, and pay for it in US dollars. The retail price you see at the pump is therefore three things stacked together: the international product price, the exchange rate used to bring it into Brazilian Real, and domestic taxes, levies, distribution margins and (often) subsidies.
Because the dollar cost is converted at the official exchange rate rather than the parallel one, fuel in countries with a large parallel premium looks cheap in dollar terms when you convert at the street rate. That is why the same litre can be quoted at two very different USD equivalents above.
Petrol vs diesel vs kerosene
In Brazil, diesel is currently more expensive than petrol (6.85 vs 6.55 BRL per litre). Diesel is the fuel of transport, agriculture and generators, so governments frequently cap or subsidise it more heavily than petrol; petrol is taxed as a consumer good. Kerosene, where sold, is a household cooking and lighting fuel and is often the most heavily subsidised of all.
Only petrol and diesel are published for Brazil; kerosene and aviation fuel are not shown rather than estimated.
How to read this price
Fuel prices in Brazil change less often than exchange rates: regulated markets revise them monthly or quarterly, liberalised ones weekly. The date on this page is the date the price was published, so a figure that is a few weeks old is normal and is usually still the price at the pump.
Pump prices vary by region and station, and informal-market fuel is priced separately from official stations. Treat the figure here as the reference retail price for Brazil, and use the exchange-rate pages to understand what it means in dollars.
