Should the BMW X1 use 92 or 95 octane gasoline?
1 Answers
The BMW X1 should use 95 octane gasoline. Introduction: The 95 octane gasoline for the BMW X1 refers to the ratio of the actual gasoline's anti-knock performance compared to that of standard gasoline. The higher the octane number, the stronger the anti-knock performance. Composition: Standard gasoline is composed of isooctane and n-heptane. Isooctane has excellent anti-knock properties, with its octane rating set at 100; conversely, n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane rating set at 0. Selection Criteria: The primary criterion for selecting gasoline octane rating is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles.
