The continuous increase in fuel prices in Argentina has many drivers wondering if they really need to fill up with Premium gasoline or if they can safely opt for Super without risking their vehicle's engine. According to a report by Infobae dated July 2, 2026, the good news is that most common cars can run perfectly on the cheaper fuel.
In Argentina, gas stations primarily offer two types of gasoline, classified by their octane rating (the fuel's ability to resist premature detonation in the engine): Super Gasoline (95 octanes) and Premium Gasoline (98 octanes). For a foreigner, it is important to note that Argentine Super is equivalent to standard regular/premium gas in many countries, while Premium is a high-octane fuel meant for high-performance or specific engines.
*Prices in Argentine Pesos (ARS).
For a standard vehicle with a 48 to 50-liter tank, filling up with Super gasoline in the Autonomous City of Buenos Aires (CABA) costs around $98,000 ARS, while filling it with Premium goes up to $108,000 ARS. In the Buenos Aires Province (PBA), prices are historically higher, often exceeding $120,000 ARS for high-octane fuel.
Specialists indicate that everyday passenger cars do not require Premium. Popular models in Argentina like the Fiat Cronos, Peugeot 208, Chevrolet Onix, Renault Kwid, Toyota Yaris, or VW Polo—whether naturally aspirated or with a conventional turbo—can use Super gasoline without compromising the engine's lifespan, as 95-octane fuel meets the manufacturers' requirements.
Fuel quality standards in Argentina have improved significantly over the last two decades, keeping pace with the technical evolution of modern engines. The key recommendation is to fill up at trusted service stations, as quality can vary depending on the maintenance of the underground facilities.
To keep the injection system clean, experts suggest regularly using Super and alternating with a tank of Premium every two or three fill-ups. Regarding aftermarket additives (bought separately), it is not recommended to add them to Super gasoline to simulate Premium qualities. They can stir up residual dirt from the bottom of the tank and send it to the injection system, causing damage that might not be covered by the vehicle's warranty.
The rules change for modern turbodiesel pickup trucks. Due to the demand for lower sulfur content and the high compression of these engines, automakers recommend filling up with Premium Diesel almost mandatorily. Regular diesel is only suitable for older, non-turbocharged diesel engines.
In summary: if your car runs on gasoline and is for daily use, Super is your best ally for your wallet. Fill up with peace of mind and enjoy the road!
