To open the fuel tank cap of a Honda Civic: 1. Turn off the engine, and ensure the driver's door is unlocked; 2. Press the fuel filler door located above the left-side tire until you hear a click; 3. Slowly unscrew the fuel filler cap. If a hissing sound is heard, wait until it stops before gently turning the knob to fully open the cap. Taking the 2021 Honda Civic as an example, it is a compact car with dimensions of 4517mm in length, 1799mm in width, 1434mm in height, a wheelbase of 2700mm, and a fuel tank capacity of 47 liters.

As someone who often helps neighbors with car repairs, opening the fuel tank cap on a Honda Civic is quite straightforward. Sit in the driver's seat, lean forward, and locate the small metal or plastic lever near the floor where the driver's left foot rests. It's usually at the edge of the floor mat or under a small panel. Give it a firm pull, and you'll hear a 'click' as the fuel tank cap pops open at the rear. Then, step out of the car and walk to the fuel tank at the back. You'll notice a raised section on the cap—press it gently and turn it counterclockwise to fully open. Avoid using excessive force during the process to prevent the lever from bending or the cap from getting stuck. If it doesn't respond the first time, the lever might be rusty or blocked by the floor mat. It's recommended to spray a bit of WD-40 on the lever's connection point monthly for lubrication. Also, always tighten the cap clockwise after refueling to prevent dust from entering, which can affect engine performance. This little trick can save a lot of hassle, especially on rainy days when sealing is crucial.

I just bought a car not long ago and figured out how to operate it on my own. I find the fuel tank cap design of the Honda Civic quite thoughtful. After getting into the car and sitting in the driver's seat, you can look down and see a small lever near your feet, located between the door and the seat. Pulling it will make a sound indicating the fuel tank cap has popped open. Then, get out of the car and walk to the rear, press the button or small protrusion on the fuel tank cap with your finger, and twist it to open for refueling. The steps are simple and intuitive, making it suitable for beginners. However, if the lever doesn't move at first, don't panic—check if the car is fully unlocked. Sometimes, the cap won't open if the key isn't in the start position. Once you get the hang of it, refueling takes just a few seconds. Remember to ensure the cap is tightly closed after each use to avoid fuel consumption issues. You can also wipe the lever with a clean cloth regularly to prevent it from getting stuck.

Refueling the Honda Civic is convenient. Sit in the driver's seat and locate a small lever on the left side near your feet. Gently pull it to pop open the fuel filler door. Then, go to the rear of the car, press the cap, and turn it counterclockwise to open. Avoid rushing; keep movements smooth. After refueling, close the cap by turning it clockwise. If the lever feels stiff, dust buildup might be the cause—use a brush to clean it. Ensure the lever area is free from obstructions.

Can Different Grades of Gasoline Be Mixed?

Gasoline can be mixed, and here are the relevant details: Mixing gasoline is possible: For gasoline from different companies, the state has strictly standardized the main components of additives in gasoline. Even if mixed, it will not cause harm. In emergency situations, gasoline from Sinopec and PetroChina can be mixed occasionally, but from a long-term perspective, it is not recommended to mix gasoline from different oil companies. Gasoline composition: Gasoline mainly consists of C5-C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 89, 92, and 95 based on the octane number. Gasoline is produced by refining different gasoline components obtained from petroleum refining, including straight-run gasoline components, catalytic cracking gasoline components, and catalytic reforming gasoline components, which are then blended with high-octane components. It is primarily used as fuel for spark-ignition internal combustion engines in automobiles.
