Fuel Shortage Prep: Car & Home Guide

Updated 5 November 2026 · Standard formula, shown below

This guide helps you prepare your car and household for a fuel shortage, whether it’s a temporary disruption or a longer-term supply issue. You’ll learn how to reduce your fuel dependency, store fuel safely, and keep your home running when pumps are empty or rationed. Start by assessing your current fuel usage and identifying essential needsâ€”then follow the steps below to build resilience.

What You’ll Need

Approved fuel containers (metal or high-density polyethylene, rated for gasoline/diesel)
Fuel stabilizer (for gasoline)
Basic car maintenance tools (tire gauge, oil, coolant)
Bicycle or public transit route maps
Alternative cooking source (camp stove, grill) with fuel
Battery-powered or solar chargers for electronics
Non-perishable food and water (at least 3 days’ supply)
Flashlights, batteries, and a hand-crank radio

Step-by-Step

Assess your fuel dependency. List all vehicles, generators, and equipment that use fuel. Estimate weekly usage (commute, errands, backup power). This tells you how much fuel to store and what you can cut back on.
Reduce routine fuel use. Combine trips, carpool, use public transit, bike, or walk for short distances. Work from home if possible. This immediately lowers your demand and extends any stored fuel.
Maintain your car for efficiency. Check tire pressure weekly (under-inflated tires reduce fuel economy). Change air filters if dirty. Use the recommended grade of motor oil. A well-tuned car uses less fuel and is more reliable during shortages.
Keep your gas tank at least half full. During a shortage, stations may run out quickly. A half-full tank gives you a buffer to reach an open station or evacuate if needed. Never let it drop below a quarter tank.
Store fuel safely (only if allowed). Use approved containers, fill them only 90% full to allow expansion, and add fuel stabilizer (for gasoline) according to the label. Store in a cool, ventilated area away from living spaces, ignition sources, and direct sunlight. Rotate stored fuel every 3-6 months by using it in your car or lawn mower.
Prepare your home for power outages. If you have a generator, test it monthly and store enough fuel for 24-48 hours of essential use. Have battery-powered lights, a hand-crank radio, and charged power banks. Consider a solar charger for phones.
Stock up on non-perishable food and water. In a fuel shortage, supply chains may be disrupted. Keep at least 3 days’ worth of food that needs no cooking (canned goods, dried fruit, nuts) and 1 gallon of water per person per day. If you have a camp stove or grill, store fuel for it (propane, charcoal) and use it outdoors only.
Plan alternative transportation. Map out bike routes, bus lines, and carpool options. Identify neighbors with similar destinations. If you have a bicycle, ensure it’s in good working order with a repair kit.
Create an emergency kit for your car. Include a blanket, flashlight, first-aid kit, jumper cables, water, and snacks. In a shortage, you might be stuck in line or stranded if fuel runs out.
Stay informed. Monitor local news for fuel availability updates. Sign up for emergency alerts. Know which stations typically get deliveries first (often major highways or truck stops).

Common Mistakes

Storing fuel in non-approved containers. Milk jugs and glass bottles can leak, melt, or break, causing spills and fire hazards. Always use certified containers.
Overfilling containers. Fuel expands with temperature. Leave room for expansion to prevent leaks and pressure buildup.
Forgetting to rotate stored fuel. Gasoline degrades in as little as 3 months without stabilizer. Use old fuel before it goes bad.
Panic-buying. Hoarding fuel creates artificial shortages and leaves others stranded. Buy only what you need for a reasonable emergency (e.g., 5-10 gallons).
Neglecting car maintenance. A poorly maintained car burns more fuel and is more likely to break down when you need it most.
Using generators indoors. Generators produce deadly carbon monoxide. Only run them outdoors, at least 20 feet from windows and doors.

Tips

Use a fuel siphon pump to transfer fuel from storage to your car without spills.
Install a fuel lock on your gas tank to deter theft during shortages.
Keep a list of nearby gas stations and their typical delivery days (ask staff or observe).
If you have an electric vehicle, charge it whenever possible and have a backup plan for charging during outages.
Consider a small solar panel system to power essential devices, reducing generator fuel needs.
Practice a “no-drive day” once a week to build habits and identify what you truly need fuel for.

Troubleshooting

Stored fuel smells bad or looks cloudy: This indicates degradation. Do not use it in your car; dispose of it at a hazardous waste facility or use it in a lawn mower (if it still runs).
Your car won’t start after sitting: If you stored the car with fuel, add fresh fuel and try starting. If it still won’t start, the fuel filter may be clogged; replace it if possible.
Fuel stations are out of gas: Try stations away from major highways or in residential areas. Call ahead if possible. Consider carpooling to conserve what you have.
Generator won’t run: Check fuel level, spark plug, and oil. If it ran out of fuel, prime the fuel line before restarting.
Power outage lasts longer than expected: Prioritize heating/cooling, refrigeration, and medical devices. Use your car to charge phones (but not in an enclosed garage). Conserve generator fuel by running it only a few hours at a time.

Frequently Asked Questions

How much fuel should I store? Store only what you can safely use within 3-6 months (with stabilizer). For most households, 5-10 gallons is enough for emergencies. Check local regulationsâ€”some areas limit residential fuel storage.

Can I store fuel in my garage? Yes, if it’s in approved containers and away from water heaters, furnaces, and electrical panels. Keep it in a well-ventilated area, preferably in a shed or detached garage.

How long does gasoline last in storage? Without stabilizer, about 3 months. With stabilizer, up to 6-12 months. Diesel lasts slightly longer but also degrades. Always rotate stored fuel.

What should I do if I run out of gas on the road? Pull over safely, turn on hazard lights, and call for roadside assistance. If you have a fuel can, walk to the nearest station (if safe) or wait for help. Never leave your car in a travel lane.

Is it safe to siphon gas from my car? It’s riskyâ€”gasoline is toxic and flammable. Use a siphon pump designed for fuel, and avoid getting it in your mouth. Better to keep a spare fuel can in your trunk.

Can I use cooking oil as fuel? Only in specially converted diesel engines (biodiesel). Do not pour cooking oil into a regular gas tankâ€”it will damage the engine. Stick to approved fuels.
