Should the Tayron use 92 or 95 octane gasoline?

Tayron requires the use of 95 octane gasoline. Gasoline with different octane ratings has different levels of octane numbers. The higher the octane rating, the higher the octane number, and the better the anti-knock performance of the gasoline. The appropriate octane rating to use depends on the compression ratio of the car's engine. Below is relevant information about compression ratios: 1. For a compression ratio between 7.5 and 8.0, 90 octane gasoline should be used. 2. For a compression ratio between 8.0 and 8.5, 90 to 93 octane gasoline should be used. 3. For a compression ratio between 8.5 and 9.5, 93 to 95 octane gasoline should be used. 4. For a compression ratio between 9.5 and 10, 95 to 97 octane gasoline should be used.
I've researched the Tayron, and it must use 95-octane gasoline! It's clearly printed on both the manual and fuel tank cap. Although 92-octane is cheaper, using lower-grade fuel can cause engine knocking, and over time, it may damage cylinders and burn out sensors, which would be a huge loss. 95-octane fuel has a higher octane rating, which can withstand the high compression ratio of turbocharged engines, providing more stable power and better fuel efficiency. In our car owners' group, someone insisted on using 92-octane, and within half a year, the check engine light came on, costing over 2,000 yuan in repairs. Mixing in a pinch once or twice isn't a big deal, but long-term use is definitely not advisable.
I've been driving the Tayron for three years and have a lot to say about refueling. The manufacturer clearly requires gasoline with an octane rating of 95 or above—never opt for 92 to save a few cents. Although 92 is slightly cheaper per liter, 95 burns more completely, resulting in slightly better fuel efficiency in practice. Turbocharged engines have high compression ratios; using lower-octane fuel can lead to reduced power and increased fuel consumption at best, and engine knocking or piston damage at worst. I remember once during a road trip when I couldn't find 95 and reluctantly used 92—the engine immediately sounded like a tractor, and I had to clean the fuel system on the way back. Always refuel at Sinopec or PetroChina's directly operated stations, as some smaller gas stations' 95-quality fuel is worse than standard 92.
