It is better to use 92 octane gasoline for the Changan CS75. The following is a related introduction about the Changan CS75plus: Introduction: The Changan CS75 is a compact SUV under the Changan brand. Both the high and low beam lights use LED cold light sources, which have the characteristics of high brightness, strong penetration, fast response, low energy consumption, anti-fatigue, and long service life. Configuration: Superior airbag technology for comprehensive safety protection: oversized side air curtain size, featuring 100% window coverage and anti-rollover design; rapid deployment within 0.03 seconds, millisecond-level response for timely protection; 6 airbags to build a comprehensive safety barrier; equipped with Bosch's latest generation airbag controller and 4 airbag sensors, significantly improving safety performance.
The fuel tank cap of the Changan CS75 indicates that it can use 92-octane or higher gasoline, so I usually fill up with 92-octane, which is completely sufficient and saves money. The engine tuning of this car is quite robust. Unless you frequently drive at high RPMs or travel in high-altitude areas, there's really no need to use 95-octane. However, I once tried two tanks of 95-octane during a long trip and noticed that the engine sound was indeed smoother when overtaking on the highway. But calculating the cost, it’s 5 cents more per kilometer, making it not worth it for long-term use. Just remember not to mix different octane ratings, and it’s safer to refuel when the tank is nearly empty.
