Fuel Shortage & Rationing

When COVID-19 supply chain disruptions triggered the UK fuel crisis of September 2021, nearly 100,000 petrol stations ran dry within days — not because there was a physical shortage of fuel in the country, but because panic buying overwhelmed the distribution system. This pattern repeats reliably: a rumour or a genuine supply disruption triggers a buying rush that instantly creates the shortage people were afraid of. The people who fare best in fuel shortages are those who have quietly maintained a modest ongoing fuel reserve, who understand how to conserve what they have, and who have thought through alternatives before the crisis makes alternatives unavailable.

Before a Shortage — Building a Fuel Reserve

How Much to Store

A reasonable home fuel reserve balances practicality, cost, and safety. Most regulatory frameworks and fire codes permit households to store modest quantities of petrol:

Country/JurisdictionTypical Permitted Home Storage
UKUp to 30 litres (two 15L containers) — no notification
UK30–275 litres — requires local authority notification
US (residential)Up to 25 gallons (~95L) in approved containers
Australia250 litres in approved containers with appropriate storage

Check your local regulations before storing. Exceeding limits without notification or appropriate storage is a legal violation and a genuine fire hazard.

Fuel Storage Containers

  • Use only containers specifically approved for flammable liquid storage — these have vented closures, are made of appropriate-grade plastic or metal, and are colour-coded (red for petrol/gasoline, yellow for diesel in many jurisdictions).
  • Never use jerry cans that previously held water, food, or other liquids.
  • Never store petrol in glass containers, un-vented containers, or non-approved plastics.
  • Diesel is less flammable than petrol — safer to store in larger quantities.

Fuel Stabiliser

Petrol has a short shelf life — it degrades within 3–6 months without stabiliser, forming gum deposits that clog carburettors and fuel injectors.

  • Add a fuel stabiliser (such as Sta-Bil or PRI-G) to stored petrol.
  • Mix per instructions (typically 1 part stabiliser per 100–500 parts fuel).
  • Stabilised petrol can last 1–3 years depending on the product.
  • Diesel is more stable — generally 6–12 months without stabiliser; biofuel blends less stable.

Rotation Practice

  • Label containers with fill date.
  • Rotate fuel into your vehicle regularly and refill containers with fresh fuel.
  • A rotation cycle of 3–6 months keeps fuel fresh and ensures your supply is usable.

Storage Location

  • Store fuel in a detached garden shed, garage, or external storage structure — not inside the house.
  • Keep away from ignition sources: boilers, water heaters, electrical panels, any open flames.
  • Store at ground level, not on shelves (liquid weight + fall risk).
  • Keep in a locked enclosure if children or young people are present.
  • Ensure adequate ventilation — petrol vapour is heavier than air and will pool at floor level.

⚠️ Petrol vapour mixed with air in the right proportions is explosive. The vapour from a single litre of petrol can fill a large room. Store petrol outdoors or in well-ventilated external storage only.

During a Fuel Shortage — Rationing and Conservation

Vehicle Fuel Conservation

When fuel is scarce, every litre must do more work:

  1. Reduce speed. Fuel consumption increases roughly with the square of speed. At 70 mph vs. 55 mph, fuel use increases by approximately 25–30%.
  2. Anticipate and coast. Accelerating smoothly and braking gently (anticipating lights and junctions) reduces fuel consumption by 15–20% versus aggressive driving.
  3. Reduce idling. Modern engines use essentially no fuel when decelerating with the throttle closed (engine braking). Turn the engine off for any stop longer than 60 seconds.
  4. Tyre pressure. Under-inflated tyres increase rolling resistance and fuel consumption. Check and inflate to manufacturer recommended levels.
  5. Remove excess weight and drag. Roof racks, bike carriers, and heavy loads increase fuel consumption. Remove when not needed.
  6. Combine trips. A cold engine uses significantly more fuel than a warm one. Combining errands into a single journey when the engine is already warm saves meaningfully.
  7. Reduce air conditioning. AC increases fuel consumption by 5–15% in urban driving. Use ventilation where temperature allows.

Prioritising Fuel Use

In a genuine shortage, develop a fuel priority hierarchy:

PriorityUseReasoning
1Medical emergencies, medication collectionLife-critical
2Work (if income-critical)Livelihood
3Food and essential supply collectionSustenance
4Generator (if critical medical equipment)Life-support
5Heating fuel (winter)Comfort and safety
6Non-essential travelDefer

Generator Fuel Rationing

If running a generator on limited fuel:

  1. Run only for essential loads. Identify the minimum power draw: charging phones and battery packs, running a medical device, or keeping a freezer cold for critical food.
  2. Run in cycles. Rather than continuous operation, run the generator for 1–2 hours, charge everything, then shut down. A freezer will maintain temperature for 4–6 hours with the door closed.
  3. Calculate runtime. Know your generator's fuel consumption rate (typically listed in the manual in litres/gallons per hour at various loads). Divide your available fuel by this rate to know how long you can run.
  4. Reduce load. Every watt drawn from the generator uses fuel. Use LED lighting, run only one appliance at a time.

A typical 3 kW portable generator consumes approximately 1.5–2 litres of petrol per hour at half load. 20 litres of stored petrol = approximately 10–13 hours of generator runtime.

Finding Fuel During a Shortage

Fuel Queue Safety

If you must queue for fuel:

  1. Never leave the engine running in a stationary queue for extended periods — this wastes fuel and causes CO accumulation if the queue is enclosed (multi-storey car park).
  2. Keep a safe distance between vehicles.
  3. Have the exact payment method ready. Card readers at stations may fail or charge surcharges for small amounts.
  4. Do not confront other drivers about queue jumping. Violence at fuel queues is a documented phenomenon during shortages.
  5. Go early or late. Queues tend to be longest in the mid-morning and after work. Early morning (before 7 am) or late evening typically sees shorter queues.

Alternative Sources

  • Rural petrol stations and smaller towns often have less competition than city centre stations during a shortage.
  • Supermarket stations typically have larger storage tanks and more frequent tanker deliveries.
  • Farm supply stores in agricultural regions may carry diesel (agricultural/red diesel is dyed and has tax implications if used in road vehicles; check local law).

Alternative Transport

Reducing reliance on motor vehicles extends your fuel reserve dramatically:

Cycling

  • The most fuel-efficient transport available.
  • Maintain your bicycle before an emergency — check tyres, brakes, and chain regularly.
  • Carry a puncture repair kit.
  • A cargo bike (front or rear rack) can carry significant loads.

Electric Bicycles and Scooters

  • Rechargeable from mains electricity or solar.
  • Range of 30–80 km per charge depending on model.
  • Reduces fuel dependency for medium-distance journeys.

Walking

  • Underestimated as a practical transport mode.
  • A fit adult walks at 5–6 km/h; 10 km is a manageable 2-hour walk for most purposes.

Carpooling and Community Transport

  • Coordinate with neighbours, colleagues, and community members.
  • One vehicle carrying four people uses 25% of the fuel per person.
  • Community mutual aid networks often organise transport sharing during crises.

Public Transport

  • Even partially functional public transport dramatically reduces individual fuel needs.
  • Prioritise public transport over personal vehicle use when available during a shortage.

Long-term Shortage Planning

If a fuel shortage extends beyond days into weeks or months:

  1. Reduce fuel dependency. Identify which activities absolutely require motorised transport and which can be substituted by cycling, walking, or restructuring routines.
  2. Local supply chains. Establish relationships with local food suppliers, markets, and shops within walking or cycling distance.
  3. Vehicle sharing. Formalise carpooling arrangements with trusted people.
  4. Electric vehicle planning. If an electric vehicle is possible for your circumstances, it eliminates petrol/diesel dependency for transport.
  5. Community resilience. A community with a diversity of transport modes, local supply chains, and cooperative arrangements is far more resilient than isolated households each individually dependent on private vehicle access.
