At the end of summer 2023, a gallon of regular gas cost just a hair under $4: perhaps not the worst you’ve ever seen, but not exactly a bargain basement price either.
According to J.D. Power, Americans spend about $5,000 on gas a year, a not insignificant figure.
If you’re looking for ways to save on this expense, this guide can help. It shares seven easy ways to boost your gas mileage, meaning you’ll go farther on a tank’s worth. Read on to learn how to save.
How to Improve Gas Mileage
Gas mileage is measured in miles per gallon (mpg). If a vehicle gets 25 mpg, this means that, on average, it can be driven for 25 miles for every gallon of gas pumped into it. Overall, miles per gallon is typically higher for a vehicle during highway driving than on city streets where speeds are slower and vehicles idle at stop signs and traffic lights. Vehicles can, in fact, typically get five more mpg with highway driving than with city driving.
Fortunately, there are ways to improve gas mileage no matter where you’re driving, many of them reasonably simple. To help, here are seven money-saving ideas for better gas mileage and two busted myths.
1. Reduce the Weight
Get rid of excess weight in the vehicle by removing unnecessary items in the trunk and backseat to lower fuel consumption. Every 100 pounds added to a car boosts fuel consumption by 2%. Think carefully about what to remove. Maybe those golf clubs don’t have to perpetually stay in your trunk. Taking out a toolbox full of tools, however, might reduce the weight being carried, but those items might be sorely missed in an emergency.

2. Watch Your Speed
In general, the mileage a driver gets from a gallon of gas decreases pretty quickly when traveling more than 50 miles per hour, according to the U.S. Department of Energy (DOE). Lowering your speed by five to 10 mph can raise fuel efficiency by 7% to 14%. Why? Higher speeds decrease fuel economy because of two factors: air resistance and tire rolling resistance.
3. Keep Tires at Optimal Pressure
The DOE reports that keeping your tire pressure in the sweet spot can enhance your gas mileage. If your tires are underinflated, you can lower gas mileage about 0.2% for every drop of 1 psi (pressure per square inch) in the pressure of the tires. Overall, proper inflation can boost your mileage by up to 3%, which can add up at the pump.
4. Monitor Your Driving
Using a trip computer, drivers can receive immediate feedback about the impact that an action, such as the rapid acceleration of a vehicle, has on gas usage. These real-time, personalized insights into how to improve fuel economy, fuel consumption, maintenance reminders, and more.
5. Plan Your Gas Stops
Using a combination of strategies for how to improve gas mileage can help to reduce fuel costs. Having to fill up at a pricey pump, though, can negate all of that hard work. So, when out on the road, especially when away from home in unfamiliar territory, consider using apps like Gas Guru or GasBuddy. They can help you to find the most affordable gasoline in town, wherever you are when it’s time to fill up.

6. Road Trip Wisely
If you’re planning a trip and have a choice of cars to drive, some factors to consider are the car’s size (you want enough room to be comfortable as you travel as well as any luggage you bring) and its gas mileage. Using a trip calculator can estimate fuel consumption for each car so you can pick the one that will cost the least in gasoline.
7. Cold Weather Strategies
When thinking about how to get better gas mileage, take a look at the thermometer, and plan your winter driving carefully. FuelEconomy.gov states that the miles per gallon can be 15% lower, more or less, at 20°F than at 77°F. Since most of us can’t hibernate all winter long, money-saving suggestions include warming up your car for 30 seconds only and then driving gently to allow the vehicle to warm up in a more cost-efficient way. Also, combine trips whenever possible — especially in the winter.
Myths About Gas Mileage
Some strategies to improve gas mileage are tried and true, but there are still some myths that continue to be perpetuated. Here are a couple of common myths that don’t prove to be true when it comes to saving money daily on gas.
1. Refueling When Cool
Some people buy gasoline in the morning when temperatures are cooler, believing that this will help them get better gas mileage. The theory behind this idea is that cooler gas is denser, so you’ll get more bang for your buck in the mornings. However, consumer watchdogs say this won’t make any practical difference though, especially since most gas stations store the gasoline underground where temperatures are pretty stable.
2. Changing the Air Filter
In the past, people believed that dirty air filters reduced fuel economy because of lowered air intake. While studies have shown that a vehicle’s acceleration was lessened when an air filter change was overdue, swapping it out probably won’t boost fuel economy in most cars. Wondering what changed? Engine computers have the ability to compensate for the reduced airflow to maintain the right ratio between air and fuel.

Budgeting for Gasoline and More
How much can you afford to pay for gasoline each month? If you aren’t really clear about that, making a monthly budget can help. Basic steps of creating a budget include:
• Gathering all of your financial documents together
• Figuring out your monthly take-home pay
• Adding up monthly fixed and variable expenses
• Using this information to create a workable budget
While creating your budget, consider how much gas is used for needs (such as getting to work) and how much for wants (driving around town while trying to decide what restaurant to pick). One popular personal budgeting method involves dividing expenses into needs and wants and then also having a category for savings. Called the 50/30/20 rule, this method divides after-tax income in this way:
• 50% towards needs
• 30% towards wants (or discretionary expenses)
• 20% towards savings
This isn’t the only way to create a personal budget, though. There are plenty of budgeting resources to help you find the method that works best to manage your money.
The Takeaway
Gas prices can take a chunk out of the budget but by understanding a few important principles, you can help improve your gas mileage and make the most of the money you spend at the pump. Doing so can be part of taking control of your finances and managing your money well.

SoFi members with direct deposit activity can earn 4.20% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.
As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.
SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.20% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.
SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.
Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
Interest rates are variable and subject to change at any time. These rates are current as of 10/31/2024. There is no minimum balance requirement. Additional information can be found at https://www.sofi.com/legal/banking-rate-sheet.
