Rio's forecourts (BR, Ipiranga, Shell and independents) thread the Linha Vermelha/Amarela, Avenida Brasil and the Zona Sul tunnels. Flex drivers weigh etanol against gasolina per fill, and GNV (CNG) is huge here; Rio has Brazil's largest natural-gas vehicle fleet. EV charging is growing at malls and along the orla.
Local tips
- GNV is a Rio speciality; thousands of taxis run on it; dedicated stations line the main arteries.
- Use the 70% rule for ethanol vs petrol each time you fill.
- Fill before the Niterói bridge or long tunnel crossings at rush hour; queues are real.
