The placement of fuel tanks in vehicles varies across manufacturers and markets. In the past, fuel tanks were often placed in the centre of the car, but safety concerns led to the adoption of right or left-sided fuel tanks. The placement of the fuel tank is indicated by an arrow on the dashboard fuel gauge in most modern cars. For older vehicles without this feature, one can determine the side of the fuel tank by observing the position of the muffler/exhaust pipe, which is usually on the opposite side. Alternatively, one can drive alongside a reflective surface to view the entire side of the car and locate the fuel door.

The fuel cap release lever is typically found under the driver's seat
The fuel cap release lever is typically found within an arm's reach of the driver's seat, allowing the driver to open the fuel door without exiting the vehicle. This is usually located on the floor to the right side of the driver's seat, near the door, and marked by a fuel pump logo. In some cases, it may also be located near the seat adjustments or on the side of the seat itself. Alternatively, it can be found on the right side of the footwell or under the dashboard.
The placement of the lever is designed to prevent unintentional operation for safety reasons. Pulling the lever operates a pull-to-release mechanism, which releases and unlocks the fuel door. Once the outer fuel cap is released, it will spring outwards from the car body, making it visible in one of the side mirrors.
It is important to note that not all vehicles have a fuel cap release lever. Some vehicles may have a powered opener or an integrated electric release button, which can be located on the dashboard or door panel. Familiarizing yourself with the mechanism in your vehicle is essential, especially if you drive multiple cars or a new model, to ensure a hassle-free refuelling process.
Additionally, it is worth mentioning that the location of the fuel tank cap may vary depending on the make and model of the vehicle. While most cars have the fuel tank on the left side, some German automakers tend to place the filler on the right, and American cars can vary within their model lines.

Side mirrors can be used to spot the fuel tank
Firstly, you need to locate the fuel cap release lever, which is usually under the driver's seat. Pull this, and then look in your side mirrors. When you release the outer fuel cap, it will spring outwards from the car body, making it visible in one of the side mirrors. This method is recommended only when the vehicle is stationary, such as after you have pulled into the gas station.
It is worth noting that not all vehicles have a fuel cap release lever. If you are driving a vehicle without one, there are other ways to locate the fuel tank without getting out of the car. One method is to drive up next to a reflective surface, such as a window or another vehicle, and angle yourself so that you can see the reflection of your car. If you can see the fuel door in the reflection, you will know which side it is on.
Alternatively, you can look at your dashboard fuel gauge. In many modern vehicles, there is a picture of a gas pump with an arrow pointing to the side of the car where the fuel tank is located. This was invented by Ford employee Jim Moylan and first appeared in select Ford models in 1989. However, this method is not foolproof, as not all cars have this indicator arrow. In some older cars, the fuel pump icon is on the side of the fuel gauge that the fuel door is on.
In some countries, the fuel cap will be on the right side of the car if you drive on the right side of the road, and vice versa. For example, in the United States, where you drive on the right, the fuel cap is usually on the left side of the car, while in Japan, where you drive on the left, it is usually on the right. Additionally, it has been noted that for about 90% of cars, the exhaust pipe is on the opposite side of the car to the fuel tank. So, on a cold day, you might be able to figure out which side the fuel tank is on by checking where the exhaust pipe is using your rearview mirror.

The arrow on the dashboard fuel gauge points to the side of the car with the fuel tank
It can be frustrating trying to locate the fuel tank on your vehicle, especially if you are driving a rental car or one that you are unfamiliar with. In the past, people would have to stick their head out of the window at the gas station to check which side the tank was on. However, since 1988, most modern cars have been fitted with an arrow on the dashboard fuel gauge to indicate which side of the car the fuel tank is on. This idea was conceived by Ford interior trim designer Jim Moylan, who, on a rainy day in 1986, struggled to locate the filler on a company car.
The arrow on the fuel gauge points to the side of the car with the fuel tank. If your vehicle does not have an arrow, the gauge's fuel bowser icon will have the fuel hose coming out of it on the same side as your gas tank. This is the case for about 90% of cars, although there are some exceptions. For example, German automakers tend to place the filler on the right, while American cars are less consistent.
If your car does not have an arrow or icon, there are other ways to determine which side the fuel tank is on. One method is to pull the fuel cap release lever under the driver's seat and then look in your side mirrors. When you release the outer fuel cap, it should spring outwards and become visible in one of the side mirrors. Alternatively, you can drive up next to a reflective surface, such as plate glass windows, and angle your car so that you can see the reflection of one side. If you can't see the gas door in the reflection, it's probably on the other side.

In American markets, the fuel tank is usually on the right, and on the left for European markets
The placement of the fuel tank is dependent on the market the car is being sold in. In the United States, where drivers drive on the right side of the road, the fuel tank is usually placed on the right side of the car. This is because it is easier to turn into a gas station by taking a right and entering the pump on the right side. Placing the fuel tank on the right side of the car also means that the driver's door is on the left side, which is safer as the car door will be closer to the pavement or sidewalk, and the driver will not have to worry about oncoming traffic.
In contrast, in European markets, the fuel tank is usually placed on the left side of the car. This is because, in Europe, drivers drive on the left side of the road. Placing the fuel tank on the left means that the driver's door will be on the right side, which is the side closest to the road and oncoming traffic. This is safer as it means that the driver will not have to worry about opening their door into oncoming traffic when they are pulled over or parked on the side of the road.
There are some exceptions to these general rules. For example, some American cars have the fuel tank on the left side, and some European cars have the fuel tank on the right side. Additionally, the placement of the fuel tank may also depend on the design of the individual car, with manufacturers opting to place the fuel tank on one side or the other depending on the amount of room needed on each side.
It is important to note that the fuel tank itself is not usually visible from the inside of the vehicle. However, there are some ways to determine which side of the car the fuel tank is on without getting out of the car. Many cars have an arrow indicator that shows which side the fuel tank is on. Additionally, you can try looking in your side mirrors after releasing the outer fuel cap, as this will cause it to spring outwards and become visible in one of the mirrors. Alternatively, you can drive up next to a reflective surface, such as a plate glass window, and angle your car so that you can see the reflection of one side of your car. If you can't see the fuel door in the reflection, then it is probably on the other side.

The exhaust pipe is often on the opposite side of the car to the fuel tank
It is not always possible to see the fuel tank from inside a vehicle. However, there are some ways to determine which side of the car the fuel tank is on without getting out of the car. One method is to pull the fuel cap release lever under the driver's seat and then look in the side mirrors. When the outer fuel cap is released, it will spring outwards, making it visible in one of the side mirrors. Another method is to drive up next to a reflective surface, such as a window or another reflective surface, and angle the car so that you can see the reflection of one side of the car. If you cannot see the fuel tank door, it is likely on the other side.
In terms of the exhaust pipe's placement, it is often on the opposite side of the car to the fuel tank. This is true for about 90% of cars, according to one source. There are several reasons for this configuration. Firstly, it is important to keep the hot parts of the car, such as the engine and exhaust pipe, away from the flammable fuel tank. By placing the fuel tank on the opposite side of the car to the engine, there is a greater distance between these components, reducing the risk of fire or explosion in the event of a collision. Additionally, engines produce a lot of heat, and it is desirable to avoid heating up the fuel tank, as this can cause issues with performance and reliability. Residual heat from the exhaust passes across the fuel tank, but it is much less than if the tank were directly under the engine.
Another reason for the opposite placement of the exhaust pipe and fuel tank is weight distribution, particularly in performance cars. The engine is typically the heaviest component of the car, and placing the fuel tank, which can weigh around 100 lbs when full, on the opposite side helps to balance the weight distribution and improve handling. Furthermore, in countries where drivers sit on the left side of the car, such as the UK and Japan, the exhaust usually exits on the right side of the vehicle, away from the pavement. This configuration may be related to packaging considerations, as right-hand drive versions of cars often have smaller market shares and may not be as well packaged as left-hand drive models.

Frequently asked questions
You can try driving up next to a structure with plate glass windows or another reflective surface. If you angle it right, you should be able to see all of one side of your car reflected and check to see if you can find the gas door.
Yes, pull the fuel cap release lever under the driver's seat and then look in your side mirrors. When you release the outer fuel cap, it will spring outwards, making it visible in one of the side mirrors.
No, not all vehicles have a fuel cap release lever.
Yes, the majority of new cars from the past couple of decades explicitly tell you which side the fuel tank is on. Look at the dashboard fuel gauge and you'll see a picture of a gas pump with an arrow.
Manufacturers choose to put the gas tanks on different sides. One argument is that if every car had the gas tank on the same side, then gas stations would fill up on that side. Cars can simply turn around when the first pumps fill up, but this would cause congestion.
