In 2018, the 57.5% of enrolments corresponded to passenger cars and suvs powered by gasoline engines, compared to 35.8% that equipped diesel engines. This means that the gasoline has returned to dethrone diesel , which for years was the preferred option by the Spanish. And if the cars raise a lot of questions, one that's sure to almost never repaired in knowing the difference between gasoline 95 and 98. What kind of octane is best for my car? Why one is more expensive than the other? From the RACE we offer all the answers .

After the ban in 2001 of gasoline, super leaded, and the disappearance in 2008 of the super 97, which replaced the lead additives of potassium (specially designed for vehicles without catalyst), the gas stations only offer two alternatives for drivers who drive a petrol car: petrol 98 or 95.

The difference between them is in the octane or in your octane rating . What is meant by the octane number? Indicates the resistance to detonation of the fuel when it is compressed within the cylinder of an engine. In this way, the higher the octane, the higher compression ratio of the engine. Another difference is that the gasoline 98 contains a lower content of sulphur than the 95, which helps to lengthen the life of the catalyst, to reduce the consumption and improve the performance.

The advantage of this higher compression of the mixture is that it makes better use of the power energy of the gasoline and, in consequence, leads to better performance of the engine. For this reason, the gas 98 is often used in sports cars of high performance.

In contrast, gasoline 95 is designed for the rest of the vehicles, which are not high-performance, and its composition limits the emissions of particulate pollutants and helps to reduce the consumption and to keep the engine clean.

is There a difference in price?

This higher octane rating also means that the price of the gasoline 98 is more expensive . Currently in Madrid liter of petrol 98 costs 0,138 cents more than gasoline 95, while in Barcelona the difference is in the 0,11 cents. This difference means that filling a tank of 50 liters will cost between 6.9 and 5.5 euros more if you opt for the higher octane.

What I will do best for my car?

A gasoline car could use interchangeably the two types of octanajes , but each type of fuel is designed for engines with concrete, so that its indiscriminate use could have adverse consequences either to the engine or to your pocket. But nothing compared to putting petrol in a diesel or vice versa.

If the engine is designed to operate with gasoline 95 octane, but will echo petrol 98: possibly you won't notice any performance difference and the only thing you get is to pay more to fill the tank. On the other hand, if the engine is designed to operate with gasoline 98 octane but will echo petrol 95: you will notice a reduction in performance and even an increase in consumption.

so what is a better gasoline than another? No. is Depends on the use of the vehicle and to which it is addressed. If you have doubts about whether to buy a car diesel or petrol, click on the link.
