Toyota Corolla's fuel tank capacity varies by configuration, with options of 43L and 50L. The manufacturer recommends using 92-octane gasoline. Below are the steps to operate the fuel tank cap of a Toyota Corolla: 1. Locate the fuel tank cap switch below the left side of the driver's seat. 2. To open the fuel tank cap, pull the switch. 3. You can then open the fuel tank cap for refueling. Extended steps for the Toyota Corolla refueling process: 1. To open, press the left side of the fuel tank cap. 2. Turn the fuel tank cap cover to the left to remove it. 3. The fuel tank cap has a designated placement for the cover; insert it accordingly. 4. Insert the fuel nozzle into the tank. 5. The first automatic shut-off of the nozzle indicates the tank is full. Continuing to refuel will fill the expansion chamber in the tank. 6. Do not remove the nozzle immediately; leave it at the fuel inlet for 5 seconds to allow all fuel to drain into the tank. 7. Replace the fuel tank cap cover, ensuring it is tightly secured. 8. Finally, close the fuel tank cap.

I've been driving my Corolla for several years, and the fuel tank is about 53 liters. I usually fill up when the fuel light comes on, and it takes about 48 liters to reach the pump's automatic shut-off. The manual says not to exceed 50 liters for safety. Last time I went on a long trip out of town, I tried to add a bit more and almost overflowed—the pump nozzle clicked off three times. The gas station attendant told me not to be greedy, as high pump pressure can cause backflow and may allow the charcoal canister to suck in fuel, affecting the exhaust. Now I stop as soon as the pump clicks off. Anyway, in the city, a full tank is enough for about 600 kilometers. Remember, overfilling can also increase fuel consumption—carrying an extra 5-6 pounds of fuel each time isn't worth it.

I checked the manual for the Corolla's fuel tank capacity, and it varies by model year. My 2021 model has a 50-liter tank, but in reality, when the low fuel light comes on, I can only fill up about 45-48 liters because space needs to be left at the top of the tank for gasoline vapor. Last week during maintenance, the mechanic reminded me that older National V emission standard models used a 53-liter tank, while the newer ones have slightly smaller tanks. Never overfill the tank—once I filled it until I could see the fuel level sloshing at the filler neck, and during summer, the gasoline smell was particularly strong. The repair shop said this could damage the charcoal canister, and replacing it could cost over a thousand yuan. You should stop filling as soon as the pump clicks off.

The fuel tank capacity of the Corolla depends on the specific model. Mainstream models typically range between 50-55 liters, while the older hybrid version is smaller at only 43 liters. Before refueling, I usually check the fuel gauge position on the dashboard. I never fill beyond 95% capacity, and generally, the fuel pump automatically stops at around 48 liters. One time, when the display showed only 30 km of remaining range, I refueled and ended up adding 52 liters, nearly exceeding the limit. The fuel attendant explained that the tank is designed with a safety margin, and overfilling can cause gasoline to seep into the evaporation system, potentially triggering a warning light. It's advisable not to overfill, as it can affect driving safety.

I've been driving a Corolla for four years, and while the fuel tank is labeled as 50 liters, it can actually hold up to 55 liters. However, a mechanic told me that the labeled capacity and the actual usable amount are two different things. During design, about 10% of space is reserved at the top to accommodate fuel vapors, so filling up until the pump clicks off is sufficient. Once, I insisted on filling it to the brim for a long trip, and gasoline overflowed from the vent tube onto the back seat, making cleanup particularly troublesome. Now, I wait until the fuel gauge shows a quarter left and fill up about 40 liters each time, which is enough. Overfilling the tank actually increases evaporative emissions, which is also harmful to the environment.
