Those who drive have already gone through this doubt: at the time of supplying, between gasoline 95, 98, simple or additive, what is the best option anyway? The price difference between them can reach 20 cents per liter, but does the most expensive compensate? Discover the ideal gasoline for your vehicle.
The answer is not only in price or personal preference, but in the manufacturer’s recommendation and the technical characteristics of the engine itself. An inappropriate choice may not cause immediate damage, but may influence performance and efficiency over time.
Octans: What do you mean?
According to Galp, the main difference between gasoline 95 and 98 is in the number of octans. Octans measure gasoline resistance to engine compression.
The higher the number, the lower this resistance, which allows the more effective operation in engines prepared for it.
95 or 98? Depends on the type of vehicle
According to the same source, most cars can use gasoline 95, especially urban vehicles, with low to medium displacement engines.
Higher -performing cars, such as sports or more powerful turbo engine, benefit from the use of 98 gasoline, which can allow better response and efficiency.

Performance or savings?
Writes the newspaper that, although gasoline 98 can ensure a higher yield, its real advantage depends on the type of driving, the state of the engine and the conditions under which the car is used.
For those who lead essentially in town and in short routes, the difference may be little notorious.
Simple or additive gasoline
In addition to octanes, there is another variable: the presence of additives. According to Galp, additives help protect the engine by avoiding waste accumulation and corrosion.
Additive gasoline is more expensive, but theoretically it can prolong engine life and optimize its performance.
Contradictory studies
It adds the publication that, despite these theoretical advantages, a study by Deco Proteste in 2012 concluded that there were no significant differences in the state of the engines or in the consumption between simple and additive gasoline, at least in the short term.
Practical Recommendations
It refers to the same source that the best choice remains that recommended in the car manual. It is this document that indicates the ideal fuel for the car engine, and ignoring this indication can represent efficiency losses.
Cost vs yield
Explains, even when gasoline 98 is technically adequate, the yield difference obtained does not always compensate for the additional cost.
The decision must take into account the driving style and driver’s objectives: immediate savings or long term maintenance.
A possible balance
For many conductors, a commitment solution may be to use gasoline 95 regularly and resort to 98 (additive or not) occasionally, as a form of cleaning and preventive maintenance.
