Americans' fuel usage decreased during the COVID-19 pandemic
Before the pandemic, some Americans filled their cars with fuel weekly, while others did so every two weeks or once a month. This varied depending on factors such as the capacity of their fuel tank, the distance they drove, and their calculation of miles per gallon.
However, the pandemic significantly impacted Americans' fuel usage. According to the Energy Department, Americans consumed 93 quadrillion British thermal units of energy in 2020, a 7% decrease from 2019. This was the largest annual decrease in energy consumption since record-keeping began in 1949. The transportation sector was hit hard, with demand for gasoline, diesel, and jet fuel dropping by 13%, 7%, and 38% respectively. This decrease in fuel consumption can be attributed to the economic lockdowns and travel restrictions implemented to curb the spread of COVID-19. With millions of Americans staying at home, there was simply less need to put gas in their cars. Commuting to work, transportation to social functions, school drop-offs, and other non-essential driving activities were all but eliminated, leading to a drastic reduction in fuel usage.
The impact of the pandemic on fuel usage was also evident in changes to consumer spending. In the second quarter of 2020, consumer spending was down 9.8% compared to the same period in 2019. While consumer expenditures began to recover in 2021, the pandemic continued to affect certain sectors. The commercial sector saw a 7% decrease in energy use as offices and businesses shifted to remote work or temporarily closed. The industrial sector also experienced a 5% decrease in energy use as factories closed during the pandemic.
Even with the relaxation of lockdown measures, many Americans believed their driving habits would not return to pre-pandemic levels, at least in the near future. This sentiment, coupled with the significant decreases in energy consumption and consumer spending, highlights the profound impact the COVID-19 pandemic had on Americans' fuel usage.

Some Americans fill up their cars weekly
Weekly fill-ups can be influenced by the size of the fuel tank and the mileage driven. Some cars have larger fuel tanks that can accommodate more fuel, allowing for less frequent fill-ups. However, for those who drive longer distances or have lower fuel efficiency, weekly fill-ups may be necessary to ensure they have sufficient fuel for their daily commute or errands.
Additionally, individual driving habits play a role in how often Americans fill up their cars. Some individuals may prefer to fill up their tanks completely whenever the fuel light comes on, which could be once a week or once every two weeks, depending on their usage. Others may opt for more frequent, partial fill-ups to calculate their approximate miles per gallon or manage their fuel costs.
The cost of fuel and income levels can also impact how often Americans fill their tanks. In the late 1990s, an hour of work could buy up to 14 gallons of gas, but today, an hour of work may only yield 6 gallons. As fuel prices fluctuate and income levels change, Americans may adjust their filling habits, opting for more or less frequent fill-ups to manage their budgets.
Overall, while some Americans fill up their cars weekly, there is no one-size-fits-all answer to how often Americans fill their tanks. Factors such as fuel efficiency, driving distance, individual habits, fuel costs, and income levels all play a role in determining the frequency of refuelling for American drivers.

Others wait until the fuel light comes on
Many Americans choose to wait until the fuel light comes on before filling their cars with fuel. This strategy allows them to get the most out of their tank and can help calculate the approximate miles per gallon (MPG) their vehicle can achieve. For some, this means filling up their cars once a week, while for others who drive less frequently, it may be once every two weeks or even once a month.
Those who opt to wait for the fuel light typically aim for a full fill-up. This ensures they can maximise the distance they can cover before needing to refuel again. The frequency of filling up depends on various factors, including the size of the fuel tank, the car's fuel efficiency, and the distance driven daily. For instance, a car with a larger fuel tank may only require refuelling once every two weeks, even when driven regularly.
Some drivers shared that they used to wait for the low fuel light but have since adjusted their habits. They now opt to fill up their tanks when they reach the halfway mark. This approach can provide a balance between maximising fuel efficiency and maintaining a comfortable buffer before the tank is completely empty.
Waiting for the fuel light might not be the best strategy for all drivers. It can be risky, especially for those who frequently drive long distances or in areas without easily accessible gas stations. Running out of fuel mid-journey could leave them stranded, potentially requiring a costly tow or roadside assistance. Therefore, it is essential for drivers to understand their vehicle's fuel efficiency and the distance they can typically cover before the light comes on.
In conclusion, while waiting for the fuel light can be a viable option for some, it is not a universal strategy. Drivers need to consider their driving habits, vehicle specifications, and the availability of fuel stations along their regular routes to determine the optimal time to fill their tanks. Striking a balance between maximising fuel efficiency and maintaining a safe buffer is essential for a stress-free driving experience.

The average American worker can buy 6 gallons of gas per hour of work
The cost of gasoline is a significant expense for many Americans. In late 2024, the national average cost of gasoline was $3.065 per gallon, with prices varying based on location and global events. While the cost of gasoline has decreased since 2021, it still accounts for a large portion of Americans' expenses.
The amount of gasoline an average American worker can buy per hour of work has decreased over time. In the late 1990s, an hour of work could buy 14 gallons of gas, whereas now, an hour of work buys 6 gallons. This means that it would take the average worker over 3 hours to fill up a 20-gallon gas tank, compared to just 80 minutes in the 1990s.
The frequency with which Americans fill up their gas tanks varies. Some individuals fill up their tanks once a week, while others may go a month or more without filling up, depending on their driving habits and the fuel efficiency of their vehicles. The Federal Highway Administration data shows that driving habits vary significantly across the country. For example, the average driver in Wyoming travels about 2,148.2 miles per month, while the average driver in Connecticut covers less than half of that distance.
The calculation of how much gas an hour of work can buy is based on average hourly earnings and the price of gasoline. While this provides a general idea, it's important to note that individual circumstances may vary. Factors such as regional price differences, vehicle fuel efficiency, and personal spending habits can all impact how much gas an individual can purchase with their hourly earnings.

Motor gasoline is one of the most-consumed fuels in the US
The frequency with which Americans fill up their cars with fuel varies. Some individuals fill up their cars with gasoline once a week, while others do so only once a month. The variation depends on factors such as the distance driven, the size of the fuel tank, and the fuel efficiency of the vehicle. Some people also choose to fill up their tanks only when the fuel light comes on, which can vary depending on the vehicle's fuel efficiency and the distance travelled since the last refuel.
Texas and California have historically been the top two states with the highest motor gasoline consumption in the US. The transportation sector, which includes personal vehicles, public transportation, airplanes, trains, and ships, is the second-largest energy-consuming sector in the country. Within this sector, light-duty vehicles, such as cars, SUVs, and small trucks, account for about 91% of all gasoline consumption.
The high consumption of motor gasoline in the US is also reflected in the types of vehicles Americans use. Cars, sport utility vehicles, light trucks, and motorcycles all contribute to the demand for motor gasoline. Additionally, government incentives have led to an increase in annual biofuel consumption, with over 1.6 billion gallons consumed in the US.

Frequently asked questions
There is no definitive answer to this, as it depends on various factors such as the size of the fuel tank, the car's fuel efficiency, and the individual's driving habits. However, based on responses from online forums, some Americans fill up their cars once the fuel light comes on, which could be anywhere from once a week to once a month.
The frequency of refuelling depends on several factors, including the size of the fuel tank, the car's fuel efficiency (miles per gallon), and the individual's driving habits. For example, someone who drives long distances or uses their car for work may need to fill up more often than someone who only drives short distances or has a fuel-efficient vehicle.
During the COVID-19 pandemic, many Americans reduced their driving due to stay-at-home orders and the decrease in commuting, social activities, and non-essential travel. A survey conducted during this period found that over half of US drivers were filling their gas tanks less than once a month.
Americans spend a significant amount of time and money on filling their cars with fuel. According to a 2012 article, the average American worker has to work longer to buy a gallon of gasoline compared to the late 1990s. Additionally, assuming 50 refills per year, an individual spends about 170 hours annually filling their car, which equates to about 8.5% of their working hours or 3% of their waking hours.
