The fuel tank capacity of the Vela is 45 liters. The FAW Vela is based on the North American version of the ECHO. Standard fuel tank capacity for cars: Typically, small cars have a fuel tank capacity of 35-45 liters, while mid-size cars have a capacity of around 55-75 liters. A full tank usually allows for a driving range of approximately 500 kilometers. The size of the fuel tank is designed according to the vehicle's displacement and fuel consumption—larger engines with higher fuel consumption have bigger tanks, and vice versa. Generally, a full tank is designed to last for 400-600 kilometers. Lighter vehicles with smaller displacements tend to have smaller fuel tanks, whereas heavier vehicles with larger displacements naturally have larger tanks. However, most vehicles with a full tank can travel between 400-600 kilometers, with the exception of some off-road vehicles. How to check the fuel tank capacity: Nowadays, the fuel tank capacity is primarily checked by reading the fuel gauge inside the car. If there are no issues, the fuel gauge will accurately display the remaining fuel. The fuel gauge typically has 5-6 segments, each representing a portion of the remaining fuel in the tank. It is advisable to refuel when the gauge shows only two segments left to avoid running out of fuel while driving.

Back in the day, our Vela cars mostly had 45-liter fuel tanks. Although official specs stated this, you'd actually find the pump would click off at around 42 liters when refueling. This is because fuel tank designs leave space for gasoline vaporization. My 2004 1.5L manual transmission model could run nearly 600 km on a full tank. During long trips, I'd make sure to refuel when the gauge reached the last half-bar, since older cars' fuel pumps were prone to burning out. Oh, and don't overfill the tank - gasoline expansion in summer can cause overflow through the charcoal canister.

As a master mechanic with ten years of experience working on hundreds of Vela models, I can confirm the fuel tank capacity is indeed 45 liters. However, it's important to note the difference between actual capacity and nominal capacity. Every time on the lift in the repair shop, you can see Vela's saddle-shaped metal fuel tank, which has a heat shield installed near the exhaust pipe side. Older car tanks are prone to rust, especially in northern regions where de-icing agents are used. If you notice a sudden decrease in refueling volume, check whether the tank has collapsed - a clogged charcoal canister can cause negative pressure deformation in the fuel tank.

My red Weile was purchased in 2006, and I remember clearly that it has a 45-liter fuel tank. Initially, I always waited until the fuel gauge warning light came on before refueling, but later a mechanic told me this could damage the fuel pump. Now I've developed the habit of refueling when there's a quarter tank left, adding just over 30 liters each time. Once, during a family road trip, it consumed only 5.8 liters per 100 kilometers on the highway, and with a full tank, it ran over 700 kilometers. When we arrived at the hotel, there was still half a bar left on the fuel gauge.
