Will the power of the Sylphy improve with 95-octane gasoline?

The power of the Sylphy will improve with 95-octane gasoline. After using 95-octane gasoline, the engine will run more smoothly, and the throttle response will also become faster. 95-octane gasoline consists of 95% isooctane and 3% n-heptane. It is recommended to refuel at reputable gas stations to ensure high-quality fuel, which helps the engine perform better. The Sylphy has a body length of 4641mm, width of 1815mm, height of 1450mm, and a wheelbase of 2712mm. The Sylphy is a compact sedan produced by Dongfeng Nissan, equipped with a 1.6L naturally aspirated engine. Transmission options include a 5-speed manual or a CVT continuously variable transmission.
I've filled my Sylphy with 95-octane gasoline a few times, and honestly, I didn't notice any significant improvement in power. The Sylphy's engine is actually designed for 92-octane fuel, with a compression ratio of only about 10:1. While 95-octane fuel has better anti-knock properties, it doesn't make much practical difference. The only slight benefits I noticed were a somewhat quieter engine sound and smoother throttle response during long highway drives, but the actual acceleration force remained pretty much the same. When you do the math, it becomes even clearer: 95-octane costs about 0.5-0.6 yuan more per liter, which means over 30 yuan extra per full tank. The fuel savings over 100 kilometers aren't enough to offset the price difference. If you really want better performance, cleaning the throttle body during maintenance would be a more effective approach.
