Why Gas Cap Sides Can Be Different

You may notice that throughout your life, you’ve had cars with gas caps on the left side and on the right side. Why is this? Well, the location of the gas cap really depends on where the car comes from, namely which manufacturer produces the vehicle.

For instance, Japanese cars like Toyota and Mitsubishi typically place their gas caps on the left side of the vehicle. Japan a left-hand traffic country, so having the gas cap on the left side of the vehicle comes naturally to their culture. In countries with right side driving traffic, having the gas cap on the left side can be beneficial as well. Many car owners prefer the gas cap on the driver’s side.

Additionally, automakers will place gas caps on either side of the vehicle depending on how the vehicle is designed internally. Sometimes certain parts are larger or smaller, and the fuel tank fits better on the left side rather than the right side, or vice versa. In another example, domestic automakers like Chevy and Ford like to place their gas caps on the right side of the car.

Lastly, there are local, state, and federal legal requirements denoting the specifications of fuel tank location in a vehicle. Automakers must follow these regulations to ensure that the location of the fuel tank cannot cause foreseeable ignitions. This is why gas caps are never located in the back of the vehicle. In the case of the collision, it could cause the entire car to ignite into flames.
