What Are the Benefits of Using High-Octane Gasoline?

[ParkerLynn]

Using high-octane gasoline does not offer any special benefits. If you switch from low-octane gasoline to high-octane gasoline, it may not only fail to provide advantages but could also cause harm. Using high-octane gasoline in an engine designed for low-octane fuel may lead to incomplete combustion, sluggish acceleration, and delayed ignition due to insufficient compression ratio. More details are as follows: 1. Higher gasoline octane ratings are not necessarily better. The octane rating refers to the fuel's anti-knock properties—the higher the octane, the better its resistance to knocking. 2. The key factor in gasoline usage is compatibility between the engine and the fuel. Manufacturers preset parameters such as compression ratio and ignition timing in the engine control unit. 3. The appropriate gasoline octane rating for a vehicle should strictly follow the manufacturer's recommendations. The owner's manual clearly specifies the correct octane rating. As long as the owner adheres to the manual's requirements when selecting gasoline, there will be no issues.
