Can Low-Grade Cars Use High-Octane Gasoline?

[Bilbo]

It is not recommended to use high-octane gasoline; just follow the official recommendations. The reasons are as follows: 1. More expensive gasoline is not necessarily better for your car. 2. The octane number represents the gasoline's anti-knock performance, not that higher is always better. Car owners should choose the appropriate octane gasoline based on the engine compression ratio specified in the vehicle's manual. 3. Blindly selecting gasoline with an excessively high octane number can alter the ignition timing, leading to carbon deposits in the cylinders and, over time, affecting the engine's lifespan. 4. If a high-compression engine uses low-octane gasoline, it can cause knocking, accelerate component aging, and increase the likelihood of malfunctions. 5. Every car's manual specifies the required gasoline octane. Forcing the use of high-octane gasoline in a car designed for low-octane will not improve efficiency or power but may damage the engine.
