8-9 liters per kilometer. Features of Oushang X7 model: The Changan Oushang X7 is a compact SUV developed by Changan Oushang Auto, positioned as a premium urban SUV. The new car is based on Changan's global R&D center's new modular MPA-2 platform, which has the capability to develop products with three energy forms: EV, hybrid, and traditional fuel vehicles. Basic information about Changan Oushang: The Oushang X7 is equipped with a 1.5TGDI engine, delivering a maximum power of 178 horsepower (131kW) at 5500rpm and a maximum torque of 265N.m at 1450-4500rpm. It is paired with a wet 7DCT automatic transmission, which was independently developed by Changan and its UK R&D center.

I drive a Oshan X5 for daily city commuting, and it consumes the most fuel in traffic jams, reaching around 9.5 liters per 100 km. On the highway, it drops to about 6.8 liters. In summer, using the air conditioning adds another liter. Honestly, the actual fuel consumption is quite different from the official data—the manufacturer claims 6.2 liters, but I’ve never achieved that. When fully loaded or driving uphill, the fuel consumption spikes. However, compared to my friend’s Haval H6, which often hits 10 liters, the Oshan is relatively fuel-efficient. Tire pressure is also crucial—once when my tire pressure was low, fuel consumption jumped by 0.8 liters, so now I check it monthly.

The fuel consumption of Oushang varies depending on the model. For example, the Oushang X7 with an automatic transmission and a 1.5T engine has a combined fuel consumption of about 8-10 liters, and it's particularly fuel-intensive in stop-and-go city traffic. After driving my Oushang Z6 for two years, I've noticed that maintenance significantly affects fuel consumption. Last time I forgot to replace the air filter, and it burned an extra liter per 100 kilometers. I recommend regularly cleaning engine carbon deposits and replacing spark plugs. Fuel consumption is also related to driving habits. I tend to accelerate aggressively, which results in 10% higher fuel consumption compared to my neighbor's same model. On a long-distance test, maintaining a steady speed of 80 km/h on the highway, the lowest I achieved was 7.1 liters.

Test drove three Oshan models when choosing a car. The X5 manual transmission had the lowest fuel consumption: 7.5L in the city and 6L on highways. The heavier X7 automatic averaged around 9L combined. The hybrid Z6 was the most fuel-efficient, just over 5L. After a year of driving, I noticed aerodynamics significantly impact efficiency – adding roof racks increased consumption by 0.7L. Oil viscosity matters too; using the wrong grade raised fuel use by 3%. Now I strictly use manufacturer-recommended 5W-30. Weather is another factor – cold winter starts consume more fuel, with short commutes using about 15% more than spring/fall.

From an economic perspective, my Oshan X5 runs 15,000 kilometers a year. With 92-octane gasoline priced at 8 yuan per liter and a fuel consumption of 8 liters, the annual fuel cost amounts to 9,600 yuan. A sedan in the same price range would only cost 6,500 yuan. However, the cargo capacity of an SUV offsets the higher fuel consumption, as it saves me freight costs for deliveries. As the car ages, fuel consumption noticeably increases. A four-year-old car consumes 1.2 liters more fuel than a new one. It's advisable to regularly replace the oxygen sensor, as aging can lead to inaccurate fuel supply and increased consumption. Fueling techniques also save money—I avoid refueling during high-temperature periods when the fuel is denser, saving 0.3 liters per 100 kilometers in practice.

When I drove my Oshan to Tibet, I noticed significant changes in fuel consumption at high altitudes. Above 4,000 meters, the engine suffered from insufficient air intake, leading to a 12% increase in fuel consumption. A fully loaded vehicle consumed 15% more fuel than when empty. The break-in period is crucial—for the first 3,000 kilometers with my new car, I maintained a steady speed, and fuel consumption stabilized at 7.8 liters. Short trips are the most fuel-intensive, as the engine doesn’t warm up before reaching the destination, averaging up to 11 liters. Avoid filling the tank completely, and lighten the load by clearing the trunk to save fuel. Using fuel additives showed little effect for me—maintaining the engine properly is most important.
