Can Gasoline with the Same Octane Number but Different Brands Be Mixed?

[DelLondyn]

Gasoline can be mixed, and here are the relevant details: Gasoline can be mixed: For gasoline from different companies, the state has strictly standardized the main components of additives in gasoline. Even if mixed, it will not cause harm. In emergency situations, gasoline from Sinopec and PetroChina can be mixed occasionally. However, from a long-term perspective, it is not recommended to mix gasoline from different oil companies. Gasoline composition: Gasoline mainly consists of C5-C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into different grades such as 89, 92, and 95 based on the octane number. Gasoline is produced by refining various gasoline components obtained from petroleum refining, such as straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components, and then blending them with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.
