Diesel vs gasoline in Paraguay: which engine to buy in 2026
60% of Paraguay's used market runs on gasoline, 40% on diesel. But the engine that fits you depends on use, not on averages. Here's the guide with real Petropar and Carzona data.
How the Carzona used fleet splits
Of more than 11,000 active listings with declared fuel type:
- Gasoline (nafta): 6,108 listings (52%).
- Diesel: 4,062 listings (35%).
- Flex: 796 (7%) — can run on gasoline or alcohol.
- Electric/Hybrid: approximately 800 listings combined.
But the average is misleading. By segment the gap is brutal: pickups are 86% diesel, hatchbacks 98% gasoline. The engine that fits you depends on what you're buying.
How much does a liter cost in Paraguay
Current Petropar prices (Paraguay's state oil company) per public records. Private brands typically sell ₲500 to ₲1,400 more per liter. Prices update frequently: confirm current ones at petropar.gov.py.
- Nafta Kape 88 (regular gasoline): ₲6,390.
- Nafta Oikoite 93 (super): ₲6,890.
- Nafta Aratiri 97 (premium): ₲8,240.
- Diesel Porã (regular): ₲7,450.
- Diesel Mbarete (premium): ₲9,250.
Key insight: in Paraguay, regular gasoline is CHEAPER per liter than regular diesel. This flips the equation that applies in other markets where diesel is typically cheaper.
Go gasoline if...
- You drive mostly in city with dense traffic.
- Your car will be a hatchback, compact sedan or city car.
- You'll drive less than 25,000 km a year.
- You want a cheaper-to-maintain, mechanically simpler engine.
Go diesel if...
- You'll drive a pickup, large SUV or van/minivan.
- You do highway driving regularly (more than 25,000 km/year).
- You need torque for hauling or work.
- You'll keep the car many years, diesel depreciates less on pickups.
Pros of gasoline
- Cheaper to buy: the same model in gasoline usually costs less than its diesel counterpart.
- Simpler maintenance: fewer components, fewer sensors, fewer things that can fail.
- Cheaper, more available parts in any Paraguayan city.
- Smoother engine, less noise, better city experience.
- Faster cold start, especially compared to older diesels.
- In Paraguay, regular gasoline is cheaper than regular diesel, reducing diesel's theoretical savings.
Cons of gasoline
- Less fuel-efficient: on highway, a diesel can go 30-35% farther per liter (US Department of Energy).
- Less torque for heavy loads or demanding climbs.
- Engine lifespan generally lower than diesel with equivalent care.
- Higher CO2 emissions per kilometer vs diesel.
Pros of diesel
- Better fuel economy on highway and at steady speeds.
- Much more torque, ideal for pickups, large SUVs, hauling and towing.
- More durable engine: diesel typically outlasts gasoline with equivalent care.
- Better depreciation: diesel pickups and SUVs hold value better than gasoline counterparts in Paraguay.
- Paraguayan diesel (low-sulfur) works well with most Japanese imported engines.
Cons of diesel
- More expensive maintenance: injectors, high-pressure pump, turbo. When they fail, they aren't cheap.
- More expensive to buy: same model in diesel usually costs 5-15% more than gasoline.
- Modern diesel brings DPF (particulate filter) and AdBlue: requires additional maintenance and specific fuel.
- Emits more NOx and fine particulates, worse for local air quality.
- In pure city use, diesel loses most of its fuel economy edge (better on highway).
- In Paraguay, regular diesel costs more per liter than regular gasoline, reducing real savings.
What the Paraguay market says by body type
Looking at our active listings:
- 01Hatchback: 98% gasoline (2,289 gasoline vs 39 diesel). Urban compacts are gasoline territory almost exclusively.
- 02Sedan: 83% gasoline (1,610 gasoline vs 329 diesel). Allion, Premio, Corolla come mostly in gasoline.
- 03Pickup: 86% diesel (763 diesel vs 125 gasoline). Hilux, Amarok and Ranger are diesel almost by default.
- 04SUV: 72% diesel (2,163 diesel vs 826 gasoline). Large SUVs prefer diesel; compact urban SUVs lean gasoline.
- 05Van/Minivan: 64% gasoline (531 gasoline vs 299 diesel). Japanese imports like Noah, Voxy, Sienta are gasoline.
Conclusion: segment dictates fuel. Large pickup = diesel; urban hatchback = gasoline. Almost without exceptions.
The fuel math: real example
Assume a car running 15,000 km a year with average consumption of 10 km/L gasoline and 14 km/L diesel (typical 40% improvement):
- Gasoline: 15,000 km / 10 km/L = 1,500 liters × ₲6,390 = ₲9,585,000 per year.
- Diesel: 15,000 km / 14 km/L = 1,071 liters × ₲7,450 = ₲7,981,000 per year.
- Annual diesel savings: ₲1,604,000 (approximately 17% less).
But watch out: diesel pays for those savings with higher upfront cost, more expensive maintenance and pricier repairs. The real advantage depends on km driven and how many years you keep the car.
