What is the fuel consumption of the Mocha? And what type of gasoline should be used?

The fuel consumption of the Mocha 2.0T two-wheel-drive version is 7L per 100 kilometers, while the 2.0T four-wheel-drive version consumes 7.5L per 100 kilometers. It is recommended to use 92-octane gasoline, as specified in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the vehicle's user manual, you can also find it on the fuel tank cap, which will also indicate the recommended grade. Generally, the gasoline 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 if the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of new technologies, the gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline grade, the higher the octane number 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 the Mocha occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-octane gasoline, using higher-octane gasoline will not cause damage, but the increase in octane number will change 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. For vehicles recommended to use higher-octane gasoline, using lower-octane gasoline can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug ignites, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is imperceptible, it only increases noise without significant damage to the engine. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring. It is recommended to use 92-octane gasoline, as specified in the vehicle's official user manual.
I've been driving the Mocha for a while now, and the city fuel consumption really depends on how you drive it. With usual traffic jams and frequent traffic lights, it generally hovers around 10L/100km, and can spike up to 12L/100km with the AC on in summer. Given the car's size, a 2.0T engine paired with nearly 2 tons of weight, it's normal to burn more fuel in stop-and-go traffic. I always fill up with 95 octane gasoline, as clearly recommended on the fuel cap. 95 octane offers better anti-knock performance and provides superior engine protection, especially during hot summer months to prevent knocking. It's more fuel-efficient on highways, averaging around 7-8L/100km, but it's certainly not the most economical option for city commuting.
The fuel consumption of the Mocha in urban areas really tests your driving technique. Based on my daily commute records, if the average speed is below 20 km/h, 11-13 liters per 100 km is within the normal range, and it can be even higher in severe traffic jams. This car is equipped with a turbocharged engine, which is known for higher fuel consumption at low RPMs. The fuel grade must be at least 95 octane; using 92 octane fuel for a long time may cause knocking and damage the engine. I specifically checked the manual, which clearly states a minimum requirement of 95 octane. Actually, using 95 octane only costs a few cents more per kilometer, but the engine runs more smoothly and powerfully, and cold starts are much smoother.
