Should the Trumpchi M8 Use 92 or 95 Gasoline?

The Trumpchi GS8 requires 92-octane or higher quality unleaded gasoline, and using 95-octane gasoline is even better. Using fuel with an octane rating that is too low or does not meet the required standards may damage the engine or fail to meet performance requirements. Do not mix diesel into gasoline, as this can damage the fuel system and engine, and may cause the vehicle to catch fire. Below is relevant information about engine oil: Functions of Engine Oil: Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is often referred to as the "lifeblood" of a car. Choosing the right engine oil and changing it regularly helps maintain the engine in good condition and extends its lifespan. Choosing Engine Oil: When selecting engine oil, the most expensive option is not necessarily the best. Instead, the right choice should be based on the characteristics of the car's engine and the driver's habits. Engine oil can also be categorized based on winter and summer use. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there is no need to select an oil with an excellent low-temperature viscosity grade.
My experience is that the Trumpchi M8 can indeed use 92-octane gasoline, but the official manual clearly recommends 95-octane as more suitable. This vehicle is equipped with a 2.0T turbocharged engine with a relatively high compression ratio. 95-octane gasoline has better anti-knock properties, allowing the engine to fully deliver its power performance. I once used 92-octane for six months and found that fuel consumption increased by half a liter, and the engine sound became muffled. After switching back to 95, the acceleration immediately felt smoother. Doing the math reveals: although 95-octane costs a few cents more per liter, it saves an average of 0.5L per 100 kilometers, making the actual cost per kilometer about the same. It's fine to occasionally use 92-octane for city commuting, but definitely use 95 for highway driving or when using air conditioning in summer.
From the perspective of engine maintenance, I recommend sticking with 95 octane fuel. Turbocharged vehicles are particularly sensitive to fuel grades. The 4B20J1 engine in the M8 has high cylinder pressure, and using 92 octane gasoline can easily cause slight knocking. Long-term use may lead to increased carbon deposits in the combustion chamber. I have a friend who owns an auto repair shop and has seen many vehicles suffer from clogged fuel injectors due to prolonged use of low-grade fuel. Although the engine has a knock sensor that can temporarily adjust the ignition timing, it's like how a person will get stomachaches from consistently eating unsuitable food. Additionally, pay attention to fuel quality differences between seasons. In summer, 92 octane at gas stations is prone to vapor lock, while 95 octane is more stable. In fact, using 92 octane at major stations like Shell might offer better quality than 95 octane at smaller stations, but it's best to develop a habit of consistently using 95 octane.
