Changan Oushang X7 has a fuel tank capacity of 55 liters, which is the officially announced data. The fuel grade for Changan Oushang X7 is 92, with a fuel consumption of 7 to 7.4L per 100 kilometers. A full tank can cover a distance of 743 to 786km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During the actual refueling process, the amount of fuel might exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit, and there is additional space from the safe limit to the tank opening. This space is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

I've been driving my Changan Oshan X7 for over a year now, and its 55-liter fuel tank is quite practical. Typically, filling up costs me around 300 yuan, allowing me to drive over 400 kilometers, which is enough for my daily commute throughout the week. Occasionally, when going out for trips, it can last half a day on long highway drives, saving me the hassle of frequent stops at gas stations. During routine maintenance, I always ask the mechanic to check if the fuel tank cap is properly sealed to prevent leaks or dust from entering, which could affect safety. With good driving habits and proper fuel consumption control, the fuel tank capacity is very reasonably designed.

Will the 2021 Sagitar use a wet dual-clutch transmission?

2021 Sagitar does not use a wet dual-clutch transmission, the 2021 Sagitar uses a dry dual-clutch transmission. The differences between dry and wet dual-clutch transmissions are as follows: 1. Different cooling methods: The dry dual-clutch uses air cooling for heat dissipation, while the wet dual-clutch is immersed in oil, resulting in higher cooling efficiency. 2. Different operation methods: The dry clutch is a manual transmission friction plate clutch with high mechanical transmission efficiency, more complex operation, and higher failure rate. The wet clutch is an automatic transmission oil-immersed friction plate clutch with lower mechanical transmission efficiency, easier operation, and lower failure rate. 3. Dual-clutch transmissions are not suitable for frequent starts, long-term low-speed driving, or stop-and-go traffic, as they are prone to overheating, leading to failures. Once the vehicle computer issues a warning, the transmission must be stopped immediately to cool down.
