RON stands for "Research Octane Number", which is an index that measures the resistance of gasoline to backfire in an internal combustion engine. Therefore, the higher the RON, the more difficult it is for the gasoline to burn back and the more stable the engine can be.

However, the efficiency of using higher RON gasoline depends on the vehicle's engine. If the engine is designed to use gasoline with a lower RON rating, then using high RON gasoline may not result in greater efficiency, and may even damage the engine.
In addition to the RON index, there are several other indexes of gasoline such as the Motor Octane Number (MON) and the Anti-Knock Index (AKI). MON measures gasoline's resistance to backfire under high-speed operating conditions, while AKI is an average of RON and MON
In summary, when evaluating gasoline, the RON index is one of the important factors that should be considered, but it is necessary to consider the engine of the vehicle and other indicators of gasoline to make the right decision. Choose the right fuel for your car
