Why the Difference?
Argentina's Subsidized Fuel
Argentina has historically subsidized fuel prices for domestic consumption. This keeps prices artificially low compared to international markets.
Chile's Market Pricing
Chile's fuel prices more closely reflect international oil markets, with taxes comprising a significant portion of the pump price.
Border Impact
This price differential means:
- Argentine border towns see heavy Chilean fuel tourism
- Some Argentine stations near borders limit quantities
- Chile-side stations can run low when Argentines fill up

Cost Calculation Example
Scenario: 2-week Patagonia road trip, 2,500 km total Based on January 2026 prices and exchange rates
All Chile Fueling
- Consumption: 250 liters (10 L/100km)
- Price: 1,200 CLP/L average (95 octane)
- Total: 300,000 CLP ≈ $332 USD (at 903 CLP/USD)
Mixed Strategy (Argentina Priority)
- Argentina fueling: 175 liters (70%)
- Chile fueling: 75 liters (30%)
- Argentina cost: 175 × 1,700 ARS = 297,500 ARS ≈ $202 USD (official rate)
- Chile cost: 75 × 1,200 CLP = 90,000 CLP ≈ $100 USD
- Total: $302 USD
Savings: $30 (9% less with official rate)
Maximum Argentina Strategy (Blue Dollar)
If you plan routes to fuel almost entirely in Argentina and use blue dollar rate:
- Argentina fueling: 230 liters (92%) at 1,700 ARS/L
- Argentina cost: 391,000 ARS ≈ $274 USD (at 1,425 ARS blue rate)
- Chile fueling: 20 liters (8%) = 24,000 CLP ≈ $27 USD
- Total: ~$301 USD
Savings with blue rate: ~$31 USD (9% less)
Note: Savings vary with exchange rate fluctuations. The blue dollar advantage increases when the gap between official and blue rates widens.
Seasonal Price Variations
Summer (December-February)

- Chile prices relatively stable
- Remote stations may run low
Winter (May-September)
