Changan Oshan X7 has a fuel tank capacity of 55 liters, which is the officially announced data. The fuel grade for Changan Oshan 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 in the tank at all times. The fuel level is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge on the dashboard typically has 5 to 6 segments. It is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is reserved to allow for fuel expansion when the temperature rises, preventing overflow from the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated fuel tank capacity.

I've been driving the Changan Oshan X7 for a while now, and its 55-liter fuel tank capacity is quite practical, reducing range anxiety on long trips. I can make round trips from Xi'an to Chengdu without refueling, covering over 500 kilometers on a full tank, depending on road conditions and driving habits. For daily city commuting, filling up once a week is sufficient, with fuel consumption around 8L/100km, which is quite economical. The fuel cap is sturdy and well-sealed, minimizing the risk of leaks, but it's still advisable to regularly inspect the fuel filler neck and keep it clean. If the car is parked for extended periods, avoid leaving the tank empty for too long to prevent sediment buildup. Overall, the 55-liter capacity is ideal for a family SUV, offering both cost savings and peace of mind.

As someone who pays attention to vehicle details, the 55-liter fuel tank size of the Changan Oshan X7 is just right for daily use and long-distance trips. Having driven similar models, this capacity indicates strong endurance, with a full tank capable of covering over 500 kilometers. Combined with an average fuel consumption of 7-9L, it's even more fuel-efficient on highways. When refueling, avoid filling it to the brim—leave some space for fuel expansion to protect the tank. Additionally, the fuel tank is positioned low in the chassis design to prevent collision damage. During maintenance, check that the fuel pump is functioning properly to ensure an uninterrupted fuel supply. Overall, it's safe and reliable, making it suitable for ordinary drivers who prioritize stability.

Where is the windshield washer fluid filling location?

Automotive windshield washer fluid should be added through the windshield washer fluid reservoir filler port, which is located in the engine compartment of the vehicle. Here is a detailed introduction to the functions of windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal effects. 2. Antifreeze performance: It can significantly lower the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. 3. Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with unobstructed visibility. 4. Anti-static performance: After cleaning with windshield washer fluid, substances adsorbed on the glass surface can eliminate surface charges, providing anti-static properties.
