Can 92 Octane Gasoline Be Replaced with 95?
1 Answers
92 octane gasoline cannot be mixed with 95 octane if the former is not fully used up. Gasoline is a mixture, and the octane rating we usually refer to indicates the anti-knock index (i.e., octane number) of the gasoline. 92 octane and 95 octane gasoline should not be mixed. The differences between 92 octane and 95 octane gasoline are as follows: 1. Different contents of n-heptane and isooctane: The two most basic components of gasoline are n-heptane and isooctane. Isooctane has strong anti-knock properties and acts as a stabilizer for gasoline, while n-heptane is highly flammable and acts as an accelerant. These two components interact, and the higher the isooctane content, the stronger the anti-knock performance of the gasoline. 92 octane gasoline has an octane number of 92 and is suitable for mid-range cars (with relatively low compression ratios), while 95 octane gasoline has an octane number of 95 and 3 heptane. 2. The higher the octane rating, the stronger the anti-knock performance: The octane rating of gasoline is an indicator of its anti-knock properties and is essentially unrelated to cleanliness, power, or calorific value. As for particle size, there is no indication whether salt particles are yellow or white. The higher the octane rating of the gasoline, the stronger its ability to resist engine knocking. The biggest difference between 92 and 95 octane gasoline is that 95 octane has better anti-knock performance than 92 octane.
