Benefits of High Octane Number?
3 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.
I'm quite frugal in my daily driving, and higher octane fuel gives me peace of mind. Although it's slightly more expensive, it effectively prevents engine knocking, reduces component wear, and avoids the cost of major repairs. As the old saying goes, knocking is like a minor illness turning into a major problem, and higher octane reduces this risk, especially for high-compression ratio vehicles. After using it, the engine runs more smoothly, cold starts become easier, and overall maintenance costs decrease. For office workers, it may not improve fuel efficiency, but it protects engine durability. If the car breaks down on the road, repair costs can be much higher than fuel expenses. Based on my experience with several cars I've driven, high-octane fuel is a smart investment.
