What to Do If 98 Octane Gas is Mixed with 92 Octane?
1 Answers
If the vehicle's specified gasoline octane rating is 92, mixing in 98 octane fuel will not cause any issues, but long-term mixed usage should be avoided. If the vehicle's specified octane rating is 98, mixing in 92 octane fuel will increase the frequency of engine knocking and accelerate engine wear. The differences between the two: There is essentially no difference in power performance between 95 octane and 98 octane gasoline. Meaning of gasoline octane ratings: Gasoline octane ratings represent the fuel's octane number. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 98 octane consists of 98% isooctane and 2% n-heptane. The proportion of isooctane determines the anti-knock performance of different octane fuels - higher isooctane content results in better anti-knock properties.
