Benefits of High Octane Number?
2 Answers
High octane number can prevent knocking phenomena inside the engine and also allows the ignition timing to be advanced further, thereby improving the engine's power output. Relevant information about gasoline is as follows: Gasoline Grades: The gasoline grade 92 refers to a composition of 92% isooctane and 8% n-heptane; grade 95 refers to 95% isooctane and 5% n-heptane; grade 98 refers to 98% isooctane and 2% n-heptane. Gasoline Composition: Gasoline is produced by refining and blending various gasoline components such as straight-run gasoline fractions, catalytic cracking gasoline fractions, and catalytic reforming gasoline fractions obtained from petroleum refining, along with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.
As an enthusiast who frequently drives modified cars, I consider high-octane gasoline to be a secret weapon. It prevents engine knocking, especially during rapid acceleration or uphill climbs, eliminating that annoying piston slap sound while delivering smoother power output—significantly enhancing the overall driving experience. High-octane fuel allows engines to tolerate higher compression ratios, with RPMs soaring faster, making throttle response feel more direct on the racetrack, as if the car comes alive. Regular gasoline might hold back performance vehicles, but high-octane versions solve this issue while protecting pistons and spark plugs. In the long run, it reduces the risk of component damage caused by knocking. Admittedly, it may not necessarily improve fuel efficiency, but for the sake of pure driving pleasure, I always opt for premium-grade fuel. Whether in city or highway driving, it keeps my ride in peak condition, preventing unexpected breakdowns.
