Fuel costs and how to cut them
The average car fuel tank capacity is around 38 to 76 litres (10 to 20 gallons), with smaller cars tending to hold about 12 gallons and larger cars holding 15 gallons or more. The price of fuel is ever-changing and varies from state to state, so it's important to know how much fuel your car consumes and how to cut fuel costs.
Firstly, it's important to understand the term 'mpg' or 'miles per gallon', which denotes the number of miles a car travels on one gallon of gas. For example, a rating of 25 mpg means a vehicle can go 25 miles per gallon of fuel. The Environmental Protection Agency (EPA) conducts tests on vehicles to determine their final mpg rating, which is then subdivided into three categories: city, highway, and overall.
When it comes to cutting fuel costs, there are several things you can do, including:
- Improving the fuel economy of your existing vehicle or acquiring a new vehicle with better mpg.
- Ensuring your tyres are properly inflated, as under-inflated tyres can reduce fuel economy by up to 3%.
- Reducing your speed and driving less aggressively, as aggressive driving behaviours like speeding, accelerating, harsh braking, and sharp cornering can negatively affect fuel economy by up to 30%.
- Reducing the weight of your vehicle, as every extra 100 pounds of weight can lower fuel economy by 1%.
- Using telematics technology to monitor and optimise fuel usage, efficiency, and time on the road, as well as to set alerts for idling and speeding.
- Opting for a hybrid or electric vehicle, which tend to have lower fuel costs and maintenance expenses.

Miles per gallon (MPG) and how it's calculated
The average car's fuel tank capacity is around 10 to 20 gallons (38 to 76 litres). Smaller cars tend to hold about 12 gallons of gas, while larger cars can hold 15 gallons or more.
Miles per gallon (MPG) is a parameter that helps you understand how much you're spending on fuel. It is calculated by dividing the number of miles travelled by the gallons of fuel used. For example, a rating of 25 mpg means a vehicle can travel 25 miles per gallon of fuel. The Environmental Protection Agency (EPA) conducts tests on new vehicles to determine their MPG. The MPG is subdivided into three categories: city, highway, and overall. The city rating refers to driving a vehicle in stop-and-go traffic.
There are several ways to improve your fuel efficiency:
- Keep your vehicle in good shape: Using the manufacturer's recommended grade of motor oil can improve gas mileage by 1-2%. Keeping the engine properly tuned, ensuring the oxygen sensor is in good condition, and fixing any failed emissions tests can also help.
- Remove unnecessary weight: Driving a smaller, lighter car or removing heavy items from your current car can improve fuel efficiency.
- Drive at a steady speed: Aggressive acceleration and braking can decrease fuel efficiency. Maintaining a constant speed using cruise control can help reduce unnecessary acceleration and deceleration.
- Keep tires properly inflated: Under-inflated tires can lower gas mileage by 0.3% per PSI drop.
- Roll up the windows: Open windows create extra resistance at high speeds, causing the engine to work harder.
- Avoid using air conditioning: AC systems can decrease a vehicle's fuel economy by up to 25%, especially in hot climates.

Fuel tank capacity and vehicle performance
The fuel tank capacity of a vehicle plays a crucial role in determining its performance and efficiency. While the average car's fuel tank capacity falls between 10.5 and 20 gallons, there are several factors that influence this range. Firstly, the size of the vehicle is a significant determinant. Smaller cars, such as subcompact crossovers and hatchbacks, typically have smaller fuel tanks, averaging around 12 gallons. On the other hand, larger vehicles like SUVs, trucks, and minivans boast bigger fuel tanks, with some trucks accommodating up to 36 gallons.
The type of vehicle also impacts fuel tank capacity. For instance, electric and hybrid cars, known for their lower mpg or miles per gallon, tend to have smaller fuel tanks compared to conventional vehicles. SUVs, while offering average mpg, strike a balance between horsepower and fuel capacity. Heavy-duty and light-duty pickups, on the other hand, are designed for power rather than fuel economy, resulting in larger fuel tanks to support their high-performance engines.
It's worth noting that miles per gallon (mpg) is independent of fuel tank capacity. A larger fuel tank allows for longer journeys without the need for frequent refuelling stops, but it does not improve fuel efficiency. Additionally, a bigger tank means increased weight, which can impact the vehicle's overall performance and handling. Therefore, while a larger fuel tank capacity provides the convenience of reduced refuelling stops, it does not directly enhance the vehicle's performance metrics.
Fuel tank capacity also influences the cost of ownership. Larger fuel tanks require more fuel to fill, resulting in higher expenses, especially in regions with elevated fuel prices. This becomes a crucial consideration during periods of peak fuel prices. Understanding the fuel tank capacity and its associated costs can help owners make informed decisions regarding their vehicle's usage and maintenance, ensuring optimal performance and cost management.
Lastly, it is important to address the concept of reserve tank capacity in the automobile industry. Some vehicles are designed with extra tank capacity, not necessarily for additional fuel but to provide room for air and prevent vapor locking. This extra space ensures that the fuel system functions optimally and does not suffer from fuel boiling or vaporization issues, which could impact the vehicle's performance and reliability. Therefore, while reserve tank capacity may not directly enhance performance, it contributes to the overall efficiency and smooth operation of the vehicle.

Fuel tank capacity and vehicle weight
The fuel tank capacity of a vehicle is dependent on its size and type. Smaller vehicles like subcompact crossovers and other hatchback models generally have smaller fuel tanks, with an average capacity of around 10 to 12 gallons of gas. On the other hand, larger vehicles like SUVs, trucks, and minivans have bigger fuel tanks, with capacities ranging from 14 to 36 gallons or more. For instance, the Chevy Silverado 1500 has a fuel tank capacity of 28.3 gallons, while the Chevy Silverado 2500 HD or 3500 HD has a 36-gallon tank.
The weight of a vehicle is also related to its fuel tank capacity. Larger vehicles with bigger engines tend to have larger fuel tanks and, consequently, weigh more. For example, heavy-duty trucks have larger tanks to support their powerful engines and long-distance capabilities. Additionally, the term "reserve tank" refers to vehicles with extra tank capacity, which can contribute to the overall weight of the vehicle.
While fuel tank capacity does not directly impact miles per gallon (MPG) or fuel efficiency, it does affect the driving range. A larger fuel tank allows for longer distances to be travelled without the need to stop and refill. This is particularly advantageous for larger vehicles with higher fuel consumption rates.
It is important to note that the stated capacity of a fuel tank is typically less than the actual size of the tank. This is to prevent overfilling, which can cause significant expansion and additional pressure on the engine. Therefore, it is recommended to never overfill your tank when pumping gas and to avoid topping it off after the automatic shutoff engages.
In summary, the fuel tank capacity of a vehicle is influenced by its size and type, with larger and heavier vehicles tending to have bigger fuel tanks. While fuel tank capacity does not directly impact MPG, it does affect the driving range and fuel efficiency of a vehicle. Additionally, it is crucial to be mindful of the actual size of the fuel tank to prevent overfilling and potential engine issues.
