What type of fuel should the Trumpchi M6 use?
3 Answers
The Trumpchi M6 should use 92-octane gasoline, as recommended in the vehicle's official user manual. In addition to checking the appropriate fuel grade in the user manual, you can also find it indicated on the fuel tank cap. Generally, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, those between 10.0-11.5 should use 95-octane gasoline, and those with higher compression ratios should use 98-octane gasoline. However, with the use of new technologies, the compression ratio alone cannot determine the required fuel grade, as high-compression engines can also be tuned to use lower-octane fuel. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the fuel grade, the higher the octane rating and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong fuel grade for the Trumpchi M6, simply switch back to the correct grade after the current tank is used up. However, prolonged use of the wrong fuel grade can have the following effects: Using a higher-octane fuel in a vehicle designed for a lower grade will not cause damage, but the increased octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower-octane fuel in a vehicle designed for a higher grade can cause engine knocking. The significantly lower octane rating lowers the fuel's ignition point, causing premature ignition during the compression stroke. If the fuel ignites before the spark plug fires, resistance occurs during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to engine seizure.
I've been driving the Trumpchi M6 for three years, and using 92-octane gasoline has been completely fine. The recommended octane rating on the inside of the fuel cap clearly states 92 or above, so there's no need to waste money on 95-octane. The main difference between 92 and 95 is the anti-knock performance, and our car's engine has a relatively low compression ratio, so 92-octane is perfectly sufficient. What you really need to worry about is filling up with low-quality fuel from small gas stations—that's what really harms the car. Once, I tried to save money by using a no-name 92-octane, and I immediately noticed the power became sluggish. After that, I went back to Sinopec, and everything returned to normal. Remember, using 92-octane from reputable gas stations is the most cost-effective choice, and the money you save can be used for extra maintenance, which is even more worthwhile.
When it comes to MPVs, practicality and economy are key, and refueling the Trumpchi M6 is straightforward. The manual specifies using 92-octane gasoline or higher, and in practice, 92-octane works perfectly fine. While 95-octane is significantly more expensive, it doesn't enhance performance or fuel efficiency for regular family cars. The real focus should be on regularly replacing the fuel filter, especially in areas with poor fuel quality. Don't fall for gas station upsells like fuel additives—sticking with reputable 92-octane brands is far more practical. With a 55-liter fuel tank, filling up with 92-octane instead of 95 can save over 30 yuan at current prices, enough for a good set of wiper blades in a year.
