Can BMW Use 92 Octane Gasoline?

[LaIker]

BMW can use 92 octane gasoline. Refueling quantity considerations: Gasoline is charged by volume rather than weight, and it expands with heat and contracts with cold. When refueling in the morning or evening when temperatures are relatively low, the same volume of gasoline can have greater mass, resulting in significant savings. With a 15-degree temperature difference between day and night, the volume difference amounts to 0.62L. Even without considering the extra fuel, the risk of danger is lower at cooler temperatures. Avoid filling the tank completely: For regular city driving, there's no need to fill the fuel tank completely. Since city driving involves frequent stops and starts, a full tank increases engine load. It's best not to exceed 2/3 of the tank capacity. Overfilling may cause gasoline to overflow, which could flow through the pipelines into the intake manifold and flood the spark plugs. This may cause the engine to stall when accelerating, and in severe cases, prevent normal engine starting. Gasoline may even leak from the carbon canister, creating extreme danger if exposed to open flames.
