Does mixing 92 and 95 octane gasoline have any impact on cars?
1 Answers
Mixing 92 and 95 octane gasoline occasionally has no impact, but try to avoid long-term mixing as their fundamental difference lies in the octane value, which represents anti-knock performance. The following are the hazards of mixing gasoline: If 92 and 95 octane gasoline are mixed for a long time, the high anti-knock function of 95 octane gasoline will not be fully utilized, and delayed combustion may occur. The ultimate consequence of this phenomenon is incomplete combustion, leading to increased carbon deposits in the engine. This has adverse effects on the normal operation and durability of the car engine, as it may cause the pressure in the engine cylinders to fail to meet the combustion requirements of the air-fuel mixture, leading to knocking. The engine may exhibit symptoms such as weak power output, increased fuel consumption, and other adverse effects. It may also shorten the lifespan of the car's ignition system, fuel injectors, and spark plugs, and increase exhaust pollution. The reason why different fuel grades are recommended for cars is that different vehicle engines have different compression ratios. Higher octane gasoline is not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio.
