5 Best Metal Gas Cans for Long Term Storage
For long-term fuel storage, metal cans are a trusted choice. We review 5 classic, durable options that prioritize safety, leak-proof seals, and reliability.
There’s nothing quite like the sound of a generator sputtering to a stop in the middle of a power outage, or a tractor running dry at the far end of the pasture. In those moments, you realize that fuel isn’t just a commodity; it’s a lifeline. And the quality of that fuel depends entirely on how you store it.

Why Steel Beats Plastic for Long-Term Storage
Plastic gas cans are everywhere. They’re cheap, they’re light, and they get the job done for a quick trip to the gas station. But for long-term storage—the fuel you’re counting on six months or a year from now—plastic is a liability. It breathes, expands, and contracts with temperature changes, letting precious fuel vapors escape and water vapor creep in.
Modern gasoline, especially with its ethanol content, is harsh on plastic. Over time, the plastic degrades, becoming brittle and prone to cracking. Sunlight accelerates this process, breaking down the material’s integrity. You’ve seen those swollen, faded red plastic cans sitting behind a shed; they’re an accident waiting to happen.
A steel can, on the other hand, is a fortress for your fuel. It’s impermeable. Vapors don’t escape, and sunlight can’t penetrate it. A quality steel can is a buy-it-once tool that protects both your fuel and your expensive equipment. It’s a heavier investment up front, but it pays for itself by preventing the cost of a gummed-up carburetor or, worse, a dangerous leak.
Eagle Type I Safety Can: The Gold Standard
When you picture a classic metal gas can, you’re probably thinking of an Eagle. These cans are the definition of industrial-grade reliability, built from 24-gauge galvanized steel with a construction that feels like it could survive being run over. They aren’t just containers; they are safety devices.
The key features are the spring-loaded cap and the flame arrestor. The cap automatically vents excess pressure but seals tight to prevent spills and vapor loss. The brass flame arrestor—a small screen in the spout opening—prevents an external spark from igniting the fumes inside the can. This isn’t just a gimmick; it’s a critical safety feature that has prevented countless workshop fires.
Pouring from an Eagle is straightforward and controlled. You use one hand to hold the can and the other to press the lever that opens the spout. It’s a simple, effective design that has been trusted in workshops and on farms for generations. It’s the can you pass down to your kids.
Wavian Jerry Can: NATO-Spec Durability
The Wavian jerry can is an icon of rugged utility for a reason. Originally designed for military use, its design is pure function. The three-handle setup is genius; it allows for a secure one-person carry, a two-person carry when full, or an easy hand-off in a chain. You can feel the history of practical design just by picking one up.
These cans are built to strict NATO specifications. This means they have a specific steel thickness, a rust-proof interior lining, and a cam-lock cap with a locking pin that is absolutely leak-proof. You can store a Wavian can on its side without a single drop escaping. This level of security is what you need for fuel that might be stored in a vehicle or kept for emergency preparedness.
The wide spout allows for incredibly fast pouring, which is a blessing when you’re filling the 20-gallon tank on a tractor. However, this speed can be a drawback for small engines. You’ll want to invest in a dedicated nozzle attachment for filling chainsaws or tillers to avoid messy and wasteful spills. It’s a tradeoff—unmatched speed for a little less precision.
Justrite AccuFlow Can for Precise Pouring
If the Eagle is the rugged classic, the Justrite AccuFlow is the precision instrument. It takes the safety features of a Type I can and adds a layer of refinement that makes it perfect for anyone who hates spilling fuel. Its standout feature is the squeeze-grip handle, which gives you total control over the flow rate.
This can is for filling equipment with small, awkward fuel ports. The flexible metal hose lets you snake the nozzle right into the tank of a log splitter or string trimmer without needing a funnel. You can deliver a trickle of fuel or a steady stream, all with one hand. This prevents overfilling and keeps your workspace clean.
Of course, this level of engineering comes at a price. Justrite cans are among the most expensive on the market. But if you value precision and hate waste, the cost is easily justified. Less spilled fuel means less money wasted and fewer fumes in your workshop.
Behrens Galvanized Steel Can: A Classic
Get durable, rust-proof trash disposal with this 6-gallon steel can. It features a locking lid and is proudly made in the USA.
Sometimes, you just need a simple, tough bucket that holds gas. That’s the Behrens can. It’s a no-frills, galvanized steel container that gets the job done without the bells and whistles of a safety can. It’s sturdy, rust-resistant, and features an offset bottom to keep the can from sitting directly on a damp concrete floor.
This is a utility can in its purest form. It’s significantly more durable than plastic and offers better vapor protection. It’s a great choice for storing kerosene for a shop heater or for those who are comfortable with a more traditional, hands-on approach to fuel handling.
You have to be aware of what you’re giving up, though. A basic Behrens can typically lacks a self-closing lid and a flame arrestor. It’s a perfectly safe container when handled with care and common sense, but it doesn’t have the built-in safety nets of an Eagle or Justrite. It puts more of the responsibility for safety directly on the user.
Valley Industries Steel Can: Modern Utility
Valley Industries and similar brands offer a modern take on the classic jerry can, often at a more accessible price point than a true NATO-spec Wavian. They provide the same durable steel construction and familiar form factor but are designed to meet current consumer product safety regulations.
This usually means they come equipped with modern "spill-proof" spouts. While these spouts can sometimes be finicky, a well-designed one offers a good balance of safety and usability. These cans bridge the gap between old-school durability and modern requirements, making them a solid all-around choice for the hobby farm.
The key is to look for quality construction. Check for solid welds, a good seal on the cap, and a powder-coat finish that will stand up to abuse. While they may not be built for a military campaign, a good quality modern steel can from a reputable brand will serve you reliably for years.
Fuel Stabilizers: Your Can’s Best Friend
The best steel can in the world can’t save bad fuel. Modern gasoline, particularly E10, starts to degrade in as little as 30 days. Water gets absorbed, varnish forms, and the fuel’s octane rating drops, leading to hard starts and damaged carburetors.
A fuel stabilizer is non-negotiable for long-term storage. It’s a simple chemical additive that prevents the fuel from breaking down, neutralizes the harmful effects of ethanol, and stops gum and varnish from clogging your fuel lines and carburetor jets. It is the cheapest insurance you can buy for your small engines.
Make it a habit: treat your fuel the day you buy it. Don’t wait until you put the can on the shelf. Add the correct amount of stabilizer to the can before you fill it up at the gas station. This ensures it mixes thoroughly and protects every drop of fuel from day one.
Proper Can Care for Decades of Service
A steel can is an investment, and like any good tool, it requires a little care to last a lifetime. The good news is that the required maintenance is minimal but crucial for safety and longevity.
First, storage location matters. Keep your fuel cans in a detached shed or a well-ventilated outbuilding, never in a basement or attached garage where fumes could accumulate. Place them on a wooden plank or pallet to keep them off a damp concrete floor, which can cause rust over time.
Second, check your gaskets. The rubber gasket inside the cap is the most common failure point. Inspect it once a year for cracks or brittleness. Replacements are cheap and easy to install, and a fresh gasket ensures a perfect seal. Finally, label every can clearly with its contents and the date you filled it. You don’t want to be guessing if the fuel is fresh or if it’s gasoline versus a 2-stroke mix.
Choosing the right steel can isn’t about nostalgia; it’s about reliability. It’s an investment in a tool that ensures your equipment will start when you need it most. A good can, filled with stabilized fuel, is one less thing to worry about, freeing you up to focus on the work that matters.
