Do I Need to Empty the Tank When Switching from 92 to 95? Although 92 and 95 octane gasoline use the same base oil, the proportion of anti-knock agents differs. Mixing them can cause engine knocking, insufficient power, carbon deposits, and other issues. Here are the detailed explanations: Explanation 1: With equal amounts of 92 and 95 octane gasoline, the mass of sediment produced by the two grades does not show a significant difference. This indicates that high-octane gasoline does not produce less carbon deposits than low-octane gasoline. Explanation 2: Manufacturers determine the fuel grade through testing and practical trials based on China's fuel quality and road conditions.
