92 or 95?

[Adam]

Whether to use 92 or 95 gasoline for a car should be determined based on the vehicle model. Here are the specific details: There will be a sticker on the inside of the fuel tank cap indicating whether the model requires 92 or 95: If it says "recommended to use 92 or higher gasoline," then both 92 and 95 can be used. However, it is important to stick to one type consistently and not switch between 92 and 95 over time. If it says "recommended to use 95 or higher gasoline," then 92 should not be used, as using gasoline with a lower octane rating may cause engine knocking and, over time, lead to increased carbon deposits in the engine. The difference between 92 and 95 gasoline: The gasoline octane rating represents the octane number of the gasoline. The higher the octane rating, the higher the octane number, indicating better anti-knock performance of the gasoline.

Having driven for over twenty years, let me talk from an economic perspective. Gas prices are skyrocketing now, and 92-octane fuel is significantly cheaper, saving you one to two yuan per liter. For regular family cars, it's more than sufficient, and over time, you can easily save hundreds or even thousands a year. My old car's manual says it can use 92, and I've been using it for over a decade—the engine still runs smoothly, and fuel consumption isn't noticeably higher than with 95. The key is that nothing goes wrong. However, for new cars or turbocharged models, it's best to follow the manufacturer's recommendation and use 95. Otherwise, if knocking occurs and affects performance, the losses could be greater. Saving money is one thing, but it must be done under the condition that the car supports it. Blindly using 92 recklessly would be disastrous.

From the perspective of driving pleasure, I insist on using 95-octane fuel because its higher octane rating reduces engine knocking, resulting in smoother power delivery and quicker response. Especially during high-speed overtaking or climbing hills, the engine sounds quieter yet more powerful, unlike with 92-octane fuel which sometimes causes vibrations and noise that affect the experience. My car is a sports model, and after switching to 95, I noticed a slight decrease in fuel consumption and improved efficiency, which also helps protect the pistons and cylinders in the long run. Don’t compromise driving quality for small savings. If the car doesn’t specifically require 95, it might not matter, but I still recommend using premium fuel for better performance.

Simply put, whether to use 92 or 95 octane fuel depends entirely on your vehicle's manual or fuel cap instructions. These clearly specify the requirement - for example, my SUV requires 95 octane, and I never deviate from this standard practice to avoid risks like engine knocking damage or increased fuel consumption. Following manufacturer guidelines is the wisest and most hassle-free approach.
