fuel cost sao paulo to rio de janeiro
The road distance between São Paulo and Rio de Janeiro on the Presidente Dutra highway (BR-116) is roughly 430 km. Adjust your car's consumption and the local fuel price for a precise estimate.
Higher mileage per liter lowers the total fuel spend.
With round trip on, the distance doubles before the calculation.
Typical motorcycle mileage cuts the spend to less than a third of a regular car's.
It is a popular Brazilian rule of thumb that compares only the pump price of the two fuels: divide the ethanol price by the gasoline price, and if the result is below 0.70 (70%), ethanol tends to be the cheaper choice. The rule exists because ethanol holds roughly 30% less energy per liter than gasoline, so a flex-fuel car covers fewer kilometers on a liter of ethanol than on a liter of gasoline.
It is a common approximation for the Dutra route, the real figure shifts slightly (typically between 430 and 433 km) depending on the exact starting and ending neighborhoods in each city. Adjust the distance field if you know your exact route.
No, the calculator covers fuel cost only. The Dutra highway has toll plazas along the route, which need to be added separately for the trip's full cost.
Because fuel prices shift from station to station and from week to week, a fixed figure on the page would go stale fast. Type the price you see at the pump on the day of the trip for a result that reflects reality, not an old average.
