Avoid The Lines – How to Store Fuel Long Term

A generator without gas is like a rifle without ammunition. For this piece of machinery to be of any use to you outside of a very expensive and heavy paper weight, you need to have a plan for fuel storage. This is also the case if you don’t want to end up like millions of people each year who are unable to get gas after a natural emergency like Hurricane Sandy. A good fuel storage plan usually involves purchasing and properly treating a minimum amount of fuel to last you through whatever scenario you are planning for.  This might be fuel for your generators, or enough gas to get you to your bug out location. It is easier to pre-purchase fuel and store it so that in the case of an emergency, you aren’t standing in line. There are a few things to consider when you are planning to store fuel long-term that we will cover below.

What type of container should you store fuel in?

Similar to having water on hand in an emergency; having a supply of fuel in containers that protect the fuel and are easy to carry is important. Could you store gas in thousand gallon tanks buried underground? Yes, and that is my dream scenario but for now I and I assume most others will have to settle for something a little more cost-effective and portable. There are many different types of fuel containers but for gas, the most common style is plastic and red in color with a built-in spout of some form. Kerosene containers are blue, Diesel is Yellow and it is important to follow this handy color convention so that you don’t accidentally pour regular gas in your kerosene heater and fry your eyebrows off or worse.

Having a few containers of stored, stabilized fuel can make a huge difference.

You can get new fuel cans just about anywhere. Home Depot, WalMart, Lowes and any hardware store will have some options for you. Most of the new models at Walmart near me are from a company called Scepter and have a new type of nozzle which is probably the result of stupid legislation that doesn’t work well at all. The nozzle requires you to press two tabs and pull them into a position for the fuel to dispense. This doesn’t work very well and the fuel doesn’t come out smoothly. I don’t think this is necessarily Scepter’s fault and they are probably only doing what is required from government regulations.

You can also pick fuel cans up at yard-sales or salvage companies. There is a salvage company down the road from me that routinely has perfectly good fuel cans for very cheap with the old goose neck spouts. These are much superior in my opinion and if you are going to be pouring fuel out of a heavy can into a small hole I would recommend getting a good goose-neck or buying an older can. I have several of the new cans full of gas in my shed and a couple of older ones. If I need to pour anything out, I will use what is in the old style cans first and then pour my gas from the new cans into the old cans. It is just easier for me that way.

Regardless of whether you have a new or old can, the place you store your fuel should be as airtight as possible. You don’t want fumes leaking into the area you have your fuel stored and gasoline evaporates quickly when exposed to air.

Using Fuel Additives for long-term fuel storage

Gas loses its potency over time and this also applies to Diesel and Kerosene. Diesel for example if stored at lower than 70 degrees will last about 12 months without any additives provided it is kept in a sealed container. If your temperatures are much above 70 that time slips by 50% to 6 months. According to BP,

As diesel gets older a fine sediment and gum forms in the diesel brought about by the reaction of diesel components with oxygen from the air. The fine sediment and gum will block fuel filters, leading to fuel starvation and the engine stopping. Frequent filter changes are then required to keep the engine going. The gums and sediments do not burn in the engine very well and can lead to carbon and soot deposits on injectors and other combustion surfaces.

Now, what can we do to prevent issues like this and protect our fuel because you don’t want to be trying to outrun the mutant zombie bikers from Mars and have your engine stop? Additives. There are two main additives that I have run across, STA-BIL and PRI-G. PRI has several lines of additives and the –G stands for gasoline. They also have PRI-D for diesel.  PRI additives are designed to be added to your fuel on a yearly basis to maintain the fuel in the best condition possible and they even claim that if your fuel has aged already, just adding PRI-G has proven to restore the fuel to “refinery-fresh conditions”. I would rather not test that out but PRI-G does have a decent reputation.

STA-BIL 22214 Fuel Stabilizer – 32 Fl oz.

STA-BIL is one that I have personally used and does pretty much the same thing as PRI-G in terms of conditioning your fuel to last a lot longer in storage than it would without treatment. The instructions are simple, just dump the required amount in with your fuel and Voila! You should be able to safe storing fuel for at least a year with no adverse affects. I pour in the additive first and then the gas so that it is mixed as thoroughly as possible.

How Much and Where do I store my fuel?

Can you ever have too much fuel? I don’t know that you can in a real emergency. If you are unable to get to the gas station or there are rations at the pump you can never have too much. Would 500 gallons be enough? It really depends. If you have a minor power outage that lasts a few days, then you wouldn’t need that much gas at all. If we have the end of the world and there are no gas stations anymore, that 500 gallons is going to be a huge help, but it won’t last forever.

What I think is a good baseline takes into consideration the 80/20 rule. What is the likelihood that you will need this fuel for? For most people I think storing fuel for a bug out vehicle or a generator is the most common scenario to plan for. For your car, I would plan on storing as much gas as you need to get you to your bugout location and add 50% to that. So, if you needed 2 tanks of gas to get you to your retreat and your tank held 20 gallons, I would store 60 gallons of treated fuel. This way if for some reason the grid goes down, the SHTF and zombies are walking all over the gas station parking lots, you should have plenty to get you there.

For a generator, I think you have to look at what you plan to run and how long you plan to run it. 15 gallons would last me about a week as long as I was using the generator for necessities only. Of course it depends on the time of year but that is an average. Everyone should have at least one can of gas stored for emergencies but I like to store a minimum of one tank of gas for my car which is roughly 17 gallons and another 10 for the generator

Fuel should be stored in a clean, preferably cool place away from where you live. Don’t store fuel in your house if possible because that is an accident waiting to happen. If my shed blew up I would be a lot less concerned than if my house blew up.

Don’t forget to rotate

I posted in another article a couple of weeks ago about 3 common mistakes preppers make and storing fuel should be considered as well. I wouldn’t buy 50 gallons of gas, throw in some stabilizer and forget about them. Use and rotate your fuel yearly and you will be in great shape if something does require you to use your supplies. Since they blend gas differently in the Winter, I buy my fuel around January and store that for a year. Before the next January comes around I load up my gas tank in my car expending my stores and then head to the pump for a fresh batch. This way I think my fuel will be in as good a condition as possible.

Thanks for reading and if you have any thoughts, please add them in the comments below.

Thanks for the answers I was looking for about how long treated, stored, fuel can remain viable. Your reminder not to store gas and diesel in your home is a good point also, as I’m sure many would be inclined to just stack the cans in the basement. Problem is that many storage containers, certainly the older ones, are vented in order to allow for the release of expanding gases and prevent potential explosion risk. And as you said, an explosion in the shed is/would be preferable to blowing up the house and the last thing you want is a… Read more »

I use Sta-Bil for the gas for my generator. I filled all my gas cans
immediately after the Halloween power outage in 2011, and did not think
about it again. When I again lost power Thanksgiving 2014 the treated
gas fired the generator with no problems – despite the passage of three
years and no further additives.

I have an approved fire cabinet inside of my garage, that I store all of my NATO 5 gallon fuel cans. I don’t worry about fires so much that way. The good quality containers seal tightly and don’t vent, and the fire cabinet will extinguish any fires inside of the cabinet.

Geoff Gariepy

I too keep my stored gasoline in a shed separate from the house/garage in order to mitigate some of the risk. Look into steel safety cans — expensive but definitely preferable to plastic gasoline containers. Stabil works very well; I make sure I create a duct tape label attached to the can with the purchase date written in permanent marker so I know how old the fuel is and rotate once every 12 months the same way you do. In all honesty, keeping the sort of quantities of gasoline around you’re talking about is going to be a fire hazard… Read more »

I would suggest that for long term storage you store straight gasoline as in no ethanol/alcohol mixed in. If you go to http://www.pure-gas.org you will be able to find the closest retail outlet that has pure gas. Pure gasoline is much more stable than any of the ethanol blends and as such will not break down as quickly and if you treat with Stabil or Pri-G then you’re looking at being able to store it for 12+ months. As far as storing fuel, check your homeowners or renters insurance to see if there are any restrictions on how much you… Read more »

I’ve used Sta-Bil in my gasoline. It is the 10% variety also, The gasoline was stored for a year then used in the spring to run my lawn mower. Worked fine. I’ve also read in a number of places that Sta-Bil should be used in 2 cycle engines where you use 10% or so ethanol as those engines are not built to run on any ethanol. I have managed to ruin a couple two cycle engines over my lifetime so will test out that theory.

David Monroe

Won’t find many 2-cycle lawnmowers in 2017. Too much regulation. Personally, I put only Premium ethanol-free gas in my mowers and trimmer (along with the 2-cycle oil mix). It runs better and the engine lasts longer between tuneups.

Thanks for your question and comments! Apartment dwellers have special advantages and obvious disadvantages especially in situations like this. For storage, your options are limited but your needs are all the same. A lot of apartment complexes have additional storage away from the units that you can rent. Barring that, I would look to stock items that made sense in one of those storage rental units that was close by if there are any. If none of that was possible, I think I would still store a 5 gallon can somewhere for emergencies. Outside on the deck storage closet? I… Read more »

Queston…will adding stabill or other additives affect the gas being used into your car. How about the catalytic convertor ?

Mark,

It isn’t supposed to according to the manufacturer but that statement is only as good as your experience obviously. I have anecdotal evidence from others that they have had no problems with injectors. I haven’t either and have used fuel stored for over a year in both my cars and lawnmower and it worked fine.

If you have an older car that wasn’t made to handle our current ethanol mixed gas then I would check out http://www.bellperformance.com/ rather than use Stabil. As Pat indicated Stabil isn’t designed for that use.

Great article. About the”new”gas cans, go to YouTube and search for, “how to fix a new gas can.” It is very easy and works great. I started using Sta-bil and their research said their product would stabilize gas for one year. If you double the dose it would be good for two years. This HAS worked for me. I use 100 gal tanks and replace as I use. I have a second 100 gal tank that I am using Pri-g in. According to their website it is designed for comercial applications and will protect gas for years. Their test is… Read more »

I’m looking to store gasoline now. This is my plan & I’d appreciate your feedback. 55 gal steel drums that I can get cheap… $20 a drum. Held racing fuel originally. Store in back of my property in an area that is semi wooded & concealed. Also surrounded by 45 acres of woods. Put drums on wooden pallets & build a 3 sided cover two side walls & roof. This will conceal & shade drums. 4ft.X 8ft. of platform area. Store 3-4 drums at about 150-200 gals & treat the gas. Rotate them over time one barrel at a time.… Read more »
Pat

Steve,

That sounds like a decent plan. I don’t have the back woods option that you do and the only thing I can think of is that your drums could rust eventually but if they are covered as you mention that should be fine. It will give you a lot of fuel storage, but will you be able to make sure nobody steals it?

Steve: One of the things people forget, generators make noise, loud noise. I built a box out of plywood, 8 feet long and 4 feet wide. I lined the inside of the plywood box with sound deadener which I got a the local home depot. Do not put a top on it, leave the top open so heat from the generator can escape. A sound man told me that sound travels horizontal in a cone shape, and when I tested my box it was still a little noisy up close, but as you move away from the box ( 20… Read more »

I find that you can twist off the spring loaded spout on the sceptor gas cans sold at WalMart. I would recommend you buy a metal funnel with a long extension to fit in the gas fill point of your vehicle. Next point check with your community guidelines for the amount of gas you can store. If an accident occurs there will be legal reckoning to deal with. If you don’t want to put additives in your gas cans. Run your car to half a tank park in the garage and fill it up with your gas cans. Then refill… Read more »

A scenario I plan to try is a whole house natural gas generator in the basement vented to the outside to minimize my need for fuel storage. I do, however, wish to continue storing the gas in case. Thank you for the article.

Pat Henry

Thank you!

I want a whole home generator but that is on the end of my list of must buy items. We don’t routinely lose power at all so this would just be in case of something cataclysmic I think. If that were to happen, its likely the Natural gas would be shut off too. Ideally you would have a large tank of your own, but we start getting well into the tens of thousands at that point.

I’m looking at developing a “system” of storing between 120 gals and 1170 gals of gas safely and cheaply…. I’m looking at sealed 55 gal plastic barrels similar to what you might find on the net for water storage. These plastic barrels come with openings in the top that have screwed in caps to make sure they are sealed tight. Some barrels can be found cheaply having been used to hold other materials, but one needs to make sure they are totally free of whatever chemicals were previously in the barrel because mixing with gasoline could be a serious problem.… Read more »

A person I know has a 30 gallon gas caddy which he was hording gas in. I walked into his building one day and smelled the rotten oder of bad gas.

I assume the gas wasn’t treated. Do you know how old it was? I have stored gas for several months (over the winter) without treating it and it worked fine next year in the mower. My long-term storage fuel is all treated with Stabil.

Hi there, I am planning (this week) on storing 6, 5 gallon, red plastic gas cans in my garage. I will be putting them on a low shelf, and I park one truck in this two car garage.
Is this more or less safe enough to do?
I rent a house, and have no shed, and no possibility of putting the gas any where else. Any advice would be very helpful as I am new to prepping. Thank you.

Pat Henry
Guest

Storing fuel in the garage should be safe as long as you use good fuel containers that are sealed tightly. The fumes are what is flammable more so than the actual liquid so if there are no fumes escaping, the risk is lower. Obviously, you still shouldn’t be lighting fires or throwing sparks on the containers, but it should be safe. Additionally, I would make sure you have smoke alarms and fire extinguishers suitably placed just in case.

I heard on the radio there is a product that rids gas of its volatility,yet a car will still run on it. Do not know the name or were to purchase it though

Pat Henry

I don’t know that product but I have had some people contact me with a fuel replacement that can be stored for a very long time. Might be the same thing, but I don’t know why you wouldn’t simply store fuel and keep it rotated. No telling what the other stuff would do to your engine.

Bob Miller
Guest

If you are saying it is non flammable, not possible… Gas is a flammable liquid but the fumes are highly explosive…. if that property were taken from the Gas….. internal combustion would not occur. Diesel is not nearly as volatile but it wont burn in a gasoline engine for long without fouling the plugs. If that were true…. we could burn lots of stuff in our cars….. paint thinner… vodka…. who knows the list would be endless.

Or just get a generator that doesn’t run on gas. OR even better just buy a darn solar panel and a good battery. THe battery is the MOST important part. You can get a DIY solar panel for like $40-50 that puts out 80-100 watts. Plenty to run necessities. It ain’t gonna run a hot water heater or a television very well. But is can run a small heater, electric blanket, a few lights, an small electric stove (though a butane or propane stove may be smarter) As for driving to a “bug out” location, I couldn’t think of anything… Read more »

Generally you don’t want to ever store fuel where you live for obvious reasons. An apartment puts you at a little bit of a disadvantage. Do you have a storage building or friend with some spare space in their garage?

Very, VERY bad idea. Took them back but still trying to figure something out. Unfortunately I have no friends that live near enough to store anything that I could get to safely if such a crisis were to happen. But I’m wondering if I could rent a small storage space nearby and keep it there. In the meantime we will stock… Read more »

If you have a diesel car or a diesel generator and your house is heated by fuel oil, your storage problems are solved. Just siphon off fuel from the heating oil tank. Just be advised that it is “illegal” to run your car on untaxed fuel and check with your supplier to make sure you are not getting a Bio fuel heating oil mix.

When buying gas for storage you should never get the “winter” blend. In most areas it has more ethanol added to it. Not only does ethanol draw more moisture from the air, it is much less energy dense compared to gasoline (you get higher mileage with ethanol free gas, which partially makes up for it’s higher cost). Sta-Bil has been proven to be mostly kerosene. While rotating my gasoline today I found a can from two years ago that accidentally missed the 2016 rotation cycle. It had been treated with PRI-G.

I store my gas in 5 gal plastic. I add the suggested amount of a product called “seafoam ” I keep my gas for 1 year, then burn it in my pickup with no problems. Regarding plastic gas cans, where the old vent plug usto be, I drill a hole and install a car valve stem. May not be legal but it works well.

Here is another option that is available from local Briggs & Stratton dealers, depending upon the size they may need to order it for you but it is available in quart, gallon, 5 gallon, and 54 gallon drum.
