Before mentioning the advantages and disadvantages of each of them, we believe it is essential and vitally important to explain the main difference between these types of gasoline. The key difference between the two lies in their octane ratings. The higher the octane rating, the less wear is produced in the motorcycle engine and the smoother the combustion starts.

In order to know which one to use, we must take into account whether it is a low or high compression engine, since it is in this specific characteristic where the octane rating interferes. And, although on many occasions 95 or 98 gasoline can be used indistinctly, the truth is that there is always one more suitable than the other depending on the type of motorcycle. For example, it is not advisable to use 95 in high-performance engines.

Advantages and Disadvantages of 98 Gasoline for Motorcycles

The following are some of the advantages:


  • It is more efficient at combustion.
  • It is cleaner.
  • It has a greater anti-knock power than 95 since it is developed for high-performance engines that work with a high compression ratio and reach a higher number of revolutions.
  • It is compulsory (in general) for competition motorcycles, and it is recommended for almost all models of sport motorcycles.
  • It contains less sulfur in its mixture, which translates into less punishment for the catalytic converter, and as it works better or is less damaged, fuel consumption is reduced.


  • It is more expensive than 95-cent gasoline.
  • You do not notice more performance unless you have a racing or large-displacement motorcycle.

Advantages and Disadvantages of 95 Gasoline for Motorcycles

Gasoline 95, like 98, also has a number of advantages and disadvantages that must be taken into account.


  • The 95 gasoline allows for great performance in engines that are not of high benefit.
  • Its composition avoids excessive emissions of polluting particles and achieves more controlled consumption.
  • It has lower anti-knock power and is generally suitable for other engines.


  • It has a greater possibility of self-ignition.
  • As it has less octane, it can make the engine dirtier.
