Haval H2s has a fuel tank capacity of 45L, and the recommended gasoline specification for this model is 92 octane or higher unleaded gasoline. Powertrain: The Haval H2s is equipped with a GW4B15 turbocharged DOHC engine, paired with a 7-speed dual-clutch transmission. It delivers a maximum power of 110kW, a maximum torque of 210N·m, with the maximum power achieved at 5600rpm and the maximum torque available between 2200-4500rpm. Body dimensions: The Great Wall Haval H2s measures 4146mm in length, 1772mm in width, and 1638mm in height, with a wheelbase of 2550mm. The luggage compartment volume ranges from 260L to 960L, and the curb weight is 1391kg.

When I used to drive the Haval H2s, I specifically checked the manual, and the fuel tank has a capacity of 50 liters. When refueling, be careful not to wait until the red light comes on before going to the gas station, as that's not good for the fuel pump. In city driving, it can typically cover around 400 kilometers, and even more on the highway. It's recommended to use 95-octane gasoline for refueling, as this engine has a high compression ratio, and using higher-quality fuel reduces carbon buildup. Also, a reminder for new car owners: develop the habit of not filling the tank too full—stop when the pump clicks off, leaving some room for expansion is better for the fuel tank's health.

The Haval H2s has a standard 50-liter fuel tank design, which is considered above average among compact SUVs. Based on my observation of actual refueling situations, when the dashboard warning light comes on, you can typically fill about 45 liters as there are still several liters of reserve fuel at the bottom of the tank. It's recommended to add around 300 yuan worth of 95-octane gasoline each time, which is sufficient for a week's commute. When refueling, pay attention to any promotional discounts at the gas station, as using a card can often save you 20-30 yuan. Fuel quality is particularly crucial for turbocharged engines, so avoid the temptation of cheaper fuel from small, unreliable stations.

As someone who frequently drives long distances, I've tested the fuel tank capacity of the Haval H2s to be exactly 50 liters. This volume allows for approximately 550 kilometers of driving on national highways. Fuel consumption increases when using air conditioning in summer or during traffic jams, so it's advisable to always keep fuel additives in the trunk. Regarding refueling techniques, it's best to refuel when the fuel level drops to one-quarter remaining, as prolonged low fuel levels can accelerate fuel pump aging. If the fuel pump nozzle automatically stops, don't force it to add more—those extra liters only add unnecessary weight to the vehicle.

The Haval H2s has a fuel tank design capacity of 50 liters, but the first refuel for a new car can only take about 47 liters due to air in the fuel line. I've compared it with the Vezel in the same class, which only has a 40-liter tank, making this quite practical. It's recommended to refuel in the morning when temperatures are lower and gasoline density is higher for better value. When the fuel gauge needle reaches the midpoint, start planning your refueling stops, especially for highway driving. Keeping the tank more than half full in the long term can reduce condensation and prevent engine knocking.

I remember once driving a Haval H2s on a road trip, and the fuel tank took exactly 50 liters when filled up. The fuel tank is located near the right rear wheel, and it's recommended to fully insert the fuel nozzle when refueling. Fueling frequency really depends on driving habits: aggressive driving can consume up to 20% more fuel than gentle driving. For daily city commuting, 50 liters is generally enough for about two weeks. Special attention should be paid when refueling in summer, as high temperatures cause gasoline to expand. Avoid overfilling the tank, or gasoline may overflow through the vent hole, wasting money.
