What are the benefits of using high-octane gasoline?

Using high-octane gasoline can increase power for high-compression ratio engines. Here is an introduction to the advantages and disadvantages of using high-octane gasoline in cars: 1. Disadvantages of using high-octane gasoline in low-compression ratio engines: Since the cylinder pressure does not reach a certain value, the high-octane gasoline is not sufficiently compressed to reach the flammable point, resulting in incomplete combustion. This means the engine's power cannot be fully utilized, leading to wasted fuel and the potential for engine carbon deposits, which may not be worth the trade-off. 2. Advantages of using high-octane gasoline in high-compression ratio engines: In addition to using the appropriate gasoline for the vehicle, high-compression ratio engines can also use relatively higher-grade gasoline. Due to the higher octane rating, the high-compression ratio engine can burn the fuel more completely, which helps provide more power to the car.
I drive a regular family car and usually fill it with 92-octane gasoline, but when I use higher-octane fuels like 95 or 98, the difference is noticeable. The most obvious change is that the engine starts faster, especially during cold starts or in winter—the initial 'hum' is much smoother. On summer highway drives, the engine runs quieter with the AC on, and climbing hills feels easier. I've heard it helps prevent knocking—that feeling when the engine doesn't stutter—and long-term use keeps the engine in better shape. A friend who works at an auto plant mentioned that high-octane fuel has a higher octane rating, making it more resistant to high temperatures and reducing wear risks. However, I've also noticed that if the car is older or not designed for high compression, it might be a waste of money, so checking the manual is key. Overall, the short-term benefits are great, saving some maintenance hassle.
As someone with a bit of interest in cars, I particularly enjoy trying out different things, like using higher-octane gasoline. After filling up with it, the car responds more agilely when I step on the accelerator, and the sense of push-back feels a bit stronger. This is mainly because higher-octane fuel prevents pre-ignition issues, allowing the engine to accelerate without hesitation. It makes overtaking on the highway much safer, without worrying about sudden stalling. Although some say it's not cheap, for my slightly newer model, it's worth it! It also helps the fuel burn cleaner, reducing exhaust fumes, making long drives more comfortable. I recommend young drivers use this more often—enhancing driving pleasure while protecting the car—but to avoid unnecessary modifications.
I always want to save money, so I'm torn about the affordability of higher-octane gasoline. Honestly, if your car's manual requires high-octane fuel, using cheaper gas can easily cause engine problems, such as knocking, leading to higher repair costs. But if the car doesn't need it, it's just a waste. I've tried it a few times and noticed a slight drop in fuel consumption, getting an extra few dozen kilometers per tank, which counts as a small saving. In the long run, it might reduce carbon buildup and avoid major repairs. However, if you're on a tight budget, it's better to switch to a gas station with good fuel quality to ensure the purity of regular gasoline. The key is to weigh the options based on your car's condition and not blindly follow trends.
