The useful next steps differ. For vehicle costs, begin with trip planning and no-cost driving and maintenance checks. For heating or utility bills, check local energy-assistance programs before taking on major home-improvement costs.
First, identify which fuel bill is putting pressure on your budget
Transportation fuel and household energy are separate expenses, and the right response depends on which one is rising. The U.S. Department of Energy’s Low-Income Energy Affordability Data (LEAD) resource excludes transportation costs from its household energy-cost measures and points users to a separate platform for considering both burdens together: DOE LEAD Tool.
- Gasoline or diesel: Focus first on reducing unnecessary trips and avoiding driving habits or vehicle conditions that waste fuel.
- Home heating or utility energy: Check local assistance and efficiency programs; eligibility and application steps vary by state and locality.
How to spend less on vehicle fuel without making a costly change
Reduce trips where practical
Combine errands into fewer outings, carpool when it works, or use public transit, walking, cycling, or remote work where those options are available and suitable. These measures reduce the amount of fuel you need to buy; they do not require changing vehicles. DOE includes trip reduction among its fuel-saving suggestions: FuelEconomy.gov: Driving More Efficiently.
Drive smoothly and remove unused roof cargo
Avoid rapid acceleration, hard braking, and speeding. DOE’s 2021 consumer guide reports a 7%–14% fuel-economy benefit from observing speed limits and says mileage usually decreases rapidly above 50 mph. Those are general estimates, not a promise for a specific vehicle; follow posted limits and drive for safety. The guide also recommends smooth driving and notes that unnecessary roof cargo can lower fuel economy, with the effect depending on the vehicle, cargo, and speed: DOE fuel-saving guidance.
Check tire pressure against your vehicle’s specification
Use the pressure listed on the vehicle’s doorjamb placard, glove box, or owner’s manual, and check when the tires are cold. Do not use the maximum pressure molded on the tire sidewall as the target. DOE estimated in 2022 that proper inflation improves fuel economy by an average of 0.6%, and by up to 3% in some cases; the result varies and is not a guaranteed bill reduction. A working pressure gauge can help, but buying one is not necessary if you can use a gauge elsewhere. DOE vehicle maintenance guidance.
Use the recommended oil grade when maintenance is due
Check the owner’s manual and use the oil grade recommended by the vehicle manufacturer. DOE’s 2022 guidance estimates a 1%–2% fuel-economy improvement from using the correct grade. The recommendation is vehicle-specific: do not change oil early or buy specialty products solely because fuel prices have increased. DOE also says replacing a dirty air filter does not improve fuel economy in modern fuel-injected cars, although it may improve acceleration. DOE vehicle maintenance guidance.
What to do if heating fuel or utility bills are the problem
Check LIHEAP and local energy assistance
The Low Income Home Energy Assistance Program (LIHEAP) can help eligible lower-income households with home-energy bills, energy crises, weatherization, and minor energy-related repairs. Program rules and applications are administered through state and local channels, so assistance and eligibility are not guaranteed. Use DOE’s current program information to find the appropriate local route: DOE Home Energy Assistance Programs.
Ask about weatherization
DOE’s Weatherization Assistance Program (WAP) is delivered through state and local agencies and supports energy-efficiency improvements intended to lower household energy costs. DOE says that, since 1976, up to 7 million families have improved their quality of life through WAP and participating households save an average of $372 or more per year. These are program-level figures, not a prediction of an individual household’s eligibility, savings, or benefit. Check the same DOE assistance page for program information and local contacts.

Use an assessment to inform larger decisions
A home energy assessment can help identify where energy is being used and which efficiency upgrades may matter. Weatherization and other improvements can reduce energy use, but larger upgrades may require upfront spending and are not an immediate fix for a household short on cash. Begin with local assistance and assessment options rather than assuming an expensive project will pay back quickly. DOE Home Energy Assessments.

FuelEconomy.gov lets drivers compare vehicle economy and estimate fuel costs. That can help with budgeting or evaluating a vehicle purchase in the future, but replacing a vehicle is not an immediate savings solution if the purchase would add costs or debt. The tool’s estimates are for planning; actual fuel use and cost depend on the vehicle, driving, and fuel prices. Visit FuelEconomy.gov.
Quick Recap
A practical order of action
- Separate the transportation-fuel problem from the home-energy problem.
- For driving costs, reduce avoidable trips and use smoother driving habits.
- Check tire pressure using the vehicle’s specified cold-pressure target; follow the manufacturer’s oil recommendation when maintenance is due.
- For home energy costs, contact the local LIHEAP or weatherization route and ask what assistance is currently available and what eligibility rules apply.
- Consider larger efficiency work or a vehicle change only after weighing upfront cost, timing, and realistic household savings.
