In high performance or high compression ratio engines, using 98 gasoline can help achieve better performance and efficiency because it provides superior knock resistance. However, the performance difference may be negligible in many common car engines.
In general, 98 gasoline is more expensive than 95 gasoline due to its higher octane rating and further refining.
The reason many modern cars call for 95 gasoline rather than 98 gasoline has mainly to do with their compression ratio and engine design. Modern engines are generally designed to run efficiently on 95 gasoline, which is widely available.
They are optimized for a specific air-fuel mixture, and the use of 98 gasoline may not provide significant performance or efficiency benefits in these engines.
Ultimately, it is essential to follow your vehicle manufacturer’s recommendations regarding the type of gasoline to use. Cars are designed to perform optimally on a specific fuel, and using lower or higher quality fuels than recommended can cause problems with engine performance and durability.
