Is it worth fueling up in Paraguay or Argentina?

What really changes at the pump in Foz, Ciudad del Este and Puerto Iguazú
Not always: pump prices swing with the exchange rate and fuel grade. Compare the day's price and add the bridge queue.
Direct answer: Not always. Fuel prices at the border swing with the exchange rate and fuel grade, and often filling up in Foz costs the same or less than at a pump in Ciudad del Este or Puerto Iguazú. Compare the day's price before crossing just to refuel.
What's confusing
- In Paraguay, the state company Petropar publishes a subsidized list price (Kape 88 is the cheapest), but that's not what you pay at private pumps (Copetrol, Puma, Shell), which usually charge more for the grade equivalent to Brazil's regular (93 octane). Ciudad del Este adds a transport surcharge.
- In Argentina, Puerto Iguazú fuel converted at the dollar rate is usually above Foz.
Before crossing just to refuel
- Check the day's comparison in border fuel prices.
- Add the cost of the bridge queue and your time.
- To take the car across you need the Green Card and, if rented, the company's authorization.
Check the live bridge queue first.
