What type of gasoline should be used for the GAC Trumpchi GA6?
2 Answers
For normal use, the GAC Trumpchi GA6 can be fueled with 93-octane gasoline, although using 97-octane gasoline would be better. Gasoline octane ratings: Currently, gasoline available in the market comes in octane ratings such as 90, 93, 95, and 97. These numbers represent the octane rating of the gasoline, indicating its anti-knock properties, and are unrelated to the cleanliness of the gasoline. The notion that "higher-octane gasoline is cleaner" is entirely misleading. It is more scientific and economical to fuel your car according to the engine's compression ratio or the requirements specified in the vehicle's manual, as this allows the engine to perform at its best efficiency. Choosing the right octane rating: During the design phase of a car engine, the required fuel octane rating is determined based on the compression ratio. The compression ratio is a crucial structural parameter of an engine, representing the ratio of the volume of gas when the piston is at the bottom dead center (start of compression) to the volume when the piston is at the top dead center (end of compression). From the perspectives of power and fuel economy, a higher compression ratio is generally better. A higher compression ratio improves power output, thermal efficiency, and consequently enhances vehicle acceleration, top speed, and other performance metrics.
As a frequent driver of the GA6, I can tell you that using regular 92-octane unleaded gasoline is perfectly fine and offers the best value for money. The engine is designed for it. Don’t fall for the myth that 95-octane or higher is better—it’s not worth the extra cost, and the performance difference is negligible. Just make sure to fill up at reputable gas stations to avoid low-quality fuel with impurities that can clog the fuel injectors. If you occasionally want to push the car, a tank of 95-octane might make acceleration feel slightly smoother, but it’s unnecessary for daily commuting. Always check the label on the fuel cap—if it recommends 92-octane, stick to it. Don’t overcomplicate things. Regularly replacing the fuel filter keeps the system clean and saves you repair costs. From my experience, consistently using 92-octane gas extends the engine’s lifespan by several years and reduces trips to the mechanic.
