Should the BYD S7 use 92 or 95 gasoline?

[DiParker]

BYD S7 uses 92 gasoline. Here is some information about gasoline: Anti-knock property: The evaluation index of gasoline anti-knock property is the octane number, which is the gasoline grade. It is the ratio of the actual gasoline anti-knock property to that of standard gasoline. Standard gasoline is composed of isooctane and n-heptane. Isooctane has good anti-knock properties, and its octane number is defined as 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, so its octane number is defined as 0. Principle: The main basis for selecting gasoline grade is the engine's compression ratio. Parameters such as compression ratio and ignition advance angle have already been set in the engine computer. As long as the owner strictly follows the requirements in the user manual to choose gasoline, there will be absolutely no problem.
