The Regal does not have a separate fuel tank cap switch inside the car. If the car is unlocked, you can press the fuel tank cap from the outside to open it. If the car is locked, the fuel tank cap will also be locked and cannot be opened. Below is some information about the Buick Regal: 1. The new Buick Regal is equipped with two types of engines: a 1.5-liter turbocharged engine and a 2.0-liter turbocharged engine. 2. The 1.5-liter turbocharged engine delivers 170 horsepower and a maximum torque of 252 Nm, with a maximum power output at 5,600 rpm and maximum torque available between 2,000 and 4,000 rpm. 3. The 2.0-liter turbocharged engine produces 261 horsepower and a maximum torque of 350 Nm, with a maximum power output at 5,400 rpm and maximum torque available between 2,000 and 5,000 rpm.

I remember being confused the first time I opened my friend's Regal fuel tank cap, but later I figured out the trick. The Regal's fuel tank cap release is located on the floor to the left of the driver's seat—there's a small lever with a gas station symbol. After turning off the engine, give it a firm pull, and you'll hear the fuel tank cap pop open. However, note that newer Regal models come with a locking fuel cap, so if the car is locked, pulling the lever won't work. My personal habit is to unlock the car first before pulling the lever for safety. When refueling, remember to hang the plastic strap of the fuel cap on the outer cover's hook to avoid scratching the paint. Using the mechanical key to open the fuel cap is the last resort—just insert the ignition key into the fuel cap keyhole and turn it counterclockwise twice. Always turn off the engine before refueling—I've seen newbies trying to fuel up with the engine running, which is terrifying.

Veteran drivers share three good habits for opening the fuel tank cap of a Regal. First, always ensure the vehicle is turned off. After unlocking the car, use your left foot to locate the fuel cap release switch at the lower left—it's the plastic ring with a fuel pump icon near the pedal. Once you hear a click, go to the rear and press the right side of the fuel cap to pop it open. Many new Regal owners don’t know there’s a backup if the electronic switch fails: open the trunk and find the emergency pull cord behind the left rear trim panel. I’ve taught this trick to several stranded young drivers at gas stations. Also, avoid hanging the fuel cap on the pump nozzle—the rubber seal can easily get scratched.

Just helped a colleague solve a fuel tank cap issue on the Regal yesterday and noticed many overlook the details. The key sequence to open the fuel tank cap is: turn off the engine → unlock the doors → locate the fuel tank cap handle at the lower left of the driver's seat. Note the model variations: pre-2017 models have a direct physical switch—pull once to open; post-2017 models with electronic locks require the entire vehicle to be unlocked. Once on a rainy night, I encountered a frantic owner who yanked the switch so hard the plastic handle snapped. Actually, there's a mechanical switch hidden behind the left trunk liner—lift the mat to find an orange pull ring. When refueling, remember to hang the fuel tank cap on the dedicated hook to avoid scratches.

There are two ways to open the fuel tank cap of a Regal. The conventional method is to get into the driver's seat, move your left foot toward the door, find the pull ring marked with a fuel pump icon, and give it a firm tug when unlocked to open it. The unconventional method is to open the trunk and locate the emergency release handle on the left side of the inner panel (newer models have an orange pull cord, while older ones have a hidden switch). Once, at a repair shop, I saw a bizarre case where a modified seat blocked the fuel tank release, preventing the cap from opening. When refueling, ensure the fuel tank cap is fully flipped onto the side latch to prevent it from swinging. Always confirm the engine is off—new drivers often forget this. If the fuel tank cap gets stuck, call customer service; forcing it open can cause deformation.

Quick Guide to Unlocking the Regal Fuel Door in 3 Steps: After parking and turning off the engine, reach under the steering wheel to locate the plastic handle with a wavy line symbol near your left foot. For newer models, simply pull firmly when the vehicle is unlocked; older versions have no unlock restriction. Once during a road trip, I encountered an electronic lock failure and later discovered a practical mechanical pull cord hidden behind the left-side trunk liner. Remember to press the central opening point on the fuel door – some mistakenly press the anti-theft lock instead, causing it to stay shut. While refueling, you can secure the fuel door in the side-mounted dedicated slot to prevent paint contact. Crucial reminder: Always turn off the engine before refueling; a friend once ignored this and triggered dashboard warning lights.
