Reasons why the fuel gauge doesn't rise after refueling: There may be an issue with the fuel level sensor in the fuel tank. You can clean the sliding resistor of the fuel level sensor and observe if it becomes functional. If it still doesn't work, it's recommended to replace the fuel level sensor. If the fuel float isn't damaged, this situation likely indicates a problem with the instrument display, in which case the only solution is to replace the instrument. The octane ratings of gasoline (90, 93, 97 unleaded) refer to their respective percentages of isooctane (90%, 93%, 97%), which has strong anti-knock properties, meaning they contain 10%, 7%, and 3% of n-heptane, which has weaker anti-knock properties. The octane number is an indicator of gasoline's anti-knock capability in engines.
