Core principle: store fuel only in a suitable, tightly closed and undamaged can, in a location permitted for the actual quantity and jurisdiction.
Fuel can stored upright away from heat and ignition sources
A free corner is not automatically a suitable storage location.

Transport and storage rules are different

A quantity that can be transported under a private-use exemption is not automatically permitted in a home, garage, basement or shed. Storage rules can vary by country, region, building type and garage size. Tenancy agreements, insurance conditions and fire-safety requirements may add further restrictions.

Use only the right container

The can must be intended for the fuel, close securely and remain in sound condition. Do not store fuel in beverage bottles, water cans or unknown reused containers. Keep the contents clearly identified and avoid mixtures with an uncertain history.

Choose the location carefully

Keep the can upright, stable, protected from direct sun and away from ignition sources. Living rooms, bedrooms, escape routes and poorly controlled communal areas are not appropriate storage locations. Good ventilation cannot compensate for a leaking container.

Inspect regularly

Look for cracks, deformation, brittleness, corrosion, damaged seams, defective seals and fuel odour. A fixed date is not a substitute for inspecting the actual can. Plastic and metal have different ageing mechanisms, but neither is maintenance-free.

Do not promise a universal fuel shelf life

Fuel stability depends on formulation, temperature, air contact, contamination and the equipment in which it will be used. When the fuel’s history is unknown or its appearance or odour has changed, do not put it into a vehicle or generator without appropriate guidance. Use local hazardous-waste instructions for disposal.

  • No fuel odour or signs of leakage
  • Quantity limited to the real need

Frequently asked questions

How much petrol or diesel may I store in a garage?

There is no reliable universal figure. Rules depend on country, region, garage type, tenancy conditions and other local requirements.

Is a car a suitable permanent storage place?

No. Temperature changes, sunlight and proximity to passengers make a vehicle a poor permanent storage location. Carry fuel only for the necessary journey.

How long does fuel last in a can?

A reliable general period cannot be stated without the fuel specification, container, seal and storage conditions. Follow fuel supplier and equipment manufacturer information.
