Is There a Difference Between Refueling in the Morning and at Noon?

[RemingtonFitz]

There is no difference between refueling in the morning and at noon. Below are some precautions regarding the use of automotive fuel: Difference between 95 and 92 octane fuel: 95 octane gasoline consists of 5% n-heptane and 95% isooctane, while 92 octane gasoline consists of 8% n-heptane and 92% isooctane. The higher the octane number of the gasoline, the stronger its anti-knock properties, but the price will also be higher. 95 octane gasoline has a higher octane number than 92 octane gasoline, so in terms of stability, 95 octane gasoline burns more easily than 92 octane gasoline and delivers more power. 95 and 92 octane fuels should not be mixed for long-term use: Occasionally, in special circumstances, mixing the two fuels when refueling generally won't cause major issues, but long-term use is not recommended as it can lead to knocking, insufficient power, and other problems. Similarly, using 92 octane gasoline occasionally in a vehicle designed for 95 octane won't cause major issues, but long-term use will increase the frequency of knocking and accelerate engine wear.
