Hi, I ran across this canned gasoline at my local Walmart that was available in both 2-stroke and 4-stroke. (I’ve included a pic, which also shows the price.) My question would be about the viability of using the 4-stroke as an emergency fuel for my car, keeping one in the trunk “for just in case”and a few in the shed for long-term storage. Although quite expensive, the octane is correct. I am amazed at the claimed shelf life of five years in the can and two years in the tank. I was under the impression the even with Sta-bil added, gasoline would only be usable for maybe two years. Are you familiar with this fuel? If so, do you know how it’s able to last so long and if it safe for a car?
Introductory Note: The following is the first of a series of articles by JWR that will profile some of the thousands of archived SurvivalBlog articles, grouped topically.
Storing and transferring liquid fuels is topic that often comes up in conversations with my consulting clients and in letters from SurvivalBlog readers. There seems to be a lack of knowledge or misinformed voodoo out there in the general public about liquid fuel shelf life, flammability, containers, and how to transfer fuel when the power grids are down. But those questions have all been “asked and answered” in SurvivalBlog, over the course of the past 11 years.
To begin, it is important to understand that the general rule about distilled oil products is: With the exception of LPG, the more highly refined the fraction, the shorter its shelf life.
Let me back up for a moment, and describe how refining works: In … Continue reading
A very interesting and informative article, but I’d like to add a couple things. Some 500 gallon propane tanks are fitted with what’s known as a “wet leg”. It is another valve situated on the top of the tank, in addition to the main valve. It’s plumbed to a pipe running to the bottom of the tank, with its purpose being refilling smaller tanks, like 20 lb portables. It requires a specially fitted hose, the shorter and larger diameter the better; 10 feet works well in 3/4” diameter. I mention a short length as disconnecting the hose from the bottle causes you to lose whatever propane was in the hose, and larger diameter to reduce the time required for filling. I purchased three used tanks from a propane supplier, with the specific requisite that at least one have a “wet leg”. It cost the same as the other used tanks. … Continue reading
Storage Tanks and Transfer of Propane (continued)
Once the tank is full, the fill hose ball valve is closed (stopping flow into the tank), the tank bleeder is closed (if used), the pump is shut off, and then the tank valve closed, in that order. Double check that the hose and tank valves are closed. The small unloader valve between the hose ball valve and tank is opened to drain the liquid trapped between the two, so the hose adapter can be safely disconnected from the tank. Failing to bleed the liquid trapped between the tank and ball valve can cause injury as liquid can be vented towards your face when the tank adapter is unscrewed. Remember that liquid propane will freeze skin upon contact, so wear gloves and safety glasses.
Please note: Not anyone and everyone should attempt to fill a cylinder without … Continue reading
Propane, or liquefied petroleum gas (LPG), is an excellent energy source for several reasons. It stores easily and has a great shelf life. It’s portable and can be adapted for use in internal combustion engines. It can also be used as a refrigerant, and in some situations a viable weapon. Long after the grid goes kaput and gasoline has turned to varnish, propane will still be usable.
Basics of Propane
There are hundreds of thousands, if not millions, of full grill bottles stacked in exchange racks throughout the country. In addition, there’s a multitude of medium and high volume tanks scattered about where one can find propane. Super large tanks are used at industrial sites to supply large volumes of gas for manufacturing. Some municipalities use blended propane-air for large-scale distribution systems, which supply entire cities, and therefore require massive amounts of propane storage. With the right tools and the … Continue reading
JWR & HJL:
That was another great article [on Hurricane Matthew]! A suggested alternative that I have adopted is buying a turbo diesel automobile and truck. The benefits are simple and yet many people still have not discovered the option. Here are a few:
My VW tdi as an example gets about 43 miles per gallon, so with a 15 gallon fuel tank it achieves about 600 miles plus on a tank, and by adding three NATO style 5 gal metal cans (15 gallons total) in the trunk I have a 1,200 hundred mile cruising range. That is hard to beat.
Another advantage diesel in several scenarios I have been through was that diesel will still be available when regular gas is sold out. In my own testing, diesel is not nearly as volatile as gasoline.
Diesel stores for 3 to 4 years without stabilizers with … Continue reading
Good Morning, SurvivalBloggers,
SurvivalBlog recently had a very good list of hurricane preparation tips in Hurricane Matthew–Some Lessons Learned, written by a Florida resident. As a former 20+ year Florida resident I’d like to add to his excellent piece.
In Florida, hurricanes are a way of life, and the period from June 1 to November 30 is known as “hurricane season.” The period from December 1 to May 31 is known as “not hurricane season.” “Not hurricane season” is when one should be doing their preparation for the other six months. During “not hurricane season” one can find plywood on sale occasionally, generators are plentiful, frequently at reduced prices, and contractors and handymen are available.
“Not hurricane season” is when one purchases plywood (tip: thicker is better), cuts it to fit windows and vulnerable doorways, drills mounting holes in it and labels each sheet as to … Continue reading
Before someone gets hurt or blows themselves up, here are some more details on the gases in question.
Natural gas is produced primarily from high pressure gas deposits deep within the earth, and to a lesser extent as a byproduct of oil production. Natural gas is what is provided to most homes that are connected to a gas main, served by a gas company. Natural gas is primarily Methane gas, with a formula of CH4, or one Carbon atom with four Hydrogen atoms.
Methane has the disadvantage that it cannot be liquefied by compression. Natural gas must either be stored at high pressure (2000-3000 PSIG / 130 – 200 bar) for vehicle or other portable use. This is called CNG Compressed Natural Gas. Since methane is stored as a gas, the remaining volume in the cylinder can be determined by the pressure.
To store massive amounts of … Continue reading
I read the article on combustible gases. You have to be very careful with the cheap conversion kits to propane for generators; almost every one of the cheap ones do not have a device to cut off the propane if the engine stops. Like loss of spark or low oil, it will keep pouring propane into the Gen set. I have been a mechanic since 1967, and these cheap kits are very dangerous. I have seen several cause explosions. – B.L.

I just finished reading the post about different kinds of gas and saw some information I would like to correct:
Natural gas at your home is in the 4-ounce pressure range not 7 pounds. Propane used in the same way is 7-ounces.
Most propane is produced from the removal of natural gas not crude oil. Butane is also recovered in this same process.
Butane … Continue reading
In response to D.H.’s questions on gas, I offer my thoughts. Generally, I would tell anyone to use the gas specifically recommended for the equipment they intend to use. Trying to keep it simple about the different gases, an explanation of the differences follows.
The first difference between the gases is chemical makeup. Propane has three carbons atoms (and hydrogen atoms) in the molecule. Butane has four carbons, and so does its isomer iso-butane. Butane is arranged in a four carbon chain, while Iso-butane has a center carbon, with the other three carbons coming off like spokes, and they have different flash points. Natural gas is a combination of methane (one carbon) and many of these other gases. Propane, methane, and butane are all derived from natural gas through a process called fractional distillation that takes advantage of each chemical’s flash points to separate them and remove impurities. … Continue reading
The difference between CNG and piped-in gas to your home is simply pressure. The gas in my house is at 7 psi and if your thumb is big enough you can stop the flow. CNG could be as high as 3000 psi, and you find it in tanks for vehicles that burn natural gas and filling stations for natural gas burning vehicles. The difference between butane, propane, and natural gas is British Thermal Units (btu) generated by a cubic foot of each substance. From high school, a btu is the amount of energy it takes to raise one pound of water one degree Farenheit at one atmosphere of pressure. I know that propane generates 20% more heat when comparing the same quantity of that to natural gas. I’m not sure where butane falls in there. The difference in heat yield is dealt with by changing the orifice through which … Continue reading
When I read PrepperDoc, I order the stuff with the grand idea of implementation. Well, my first success with all that equipment was to take apart my son’s silent “Monkey George” alarm clock and solder in a new motor. I paid attention to voltage and dimensions and ordered it online. Success is defined based on:
It rings (quite loudly);
It does not smoke; and
My eight year old son is elated.
Best of all I kept a promise to my son. Lastly, my confidence level improved. I am sure I will have an EMP-proof antenna installation in no time.
The stray thought I have about prepping is that really you are trying to be in a position of staying out of lines so that you can live and be prosperous. The biggest line is for fuel in every news story.
To store gasoline safely and … Continue reading
Welding cable is a fine way to cut amperage loss in your line. However, since it is intended by the manufacturer to be used for welding and not solar system, it is labeled for welding and not labeled for building installation. Code inspectors want to see a certain label. They will not accept deviation. After all, an abundance of engineering went into what is in that code. Welding cable use would make pulling a system when bugging out much easier. (I am assuming there are a range of “bugging out” versions with regard to situational haste.)
Since you cannot defend a fixed position, my preps are done with an eye to rapid transportation. Supplies do not sit on shelves. They sit in bins, buckets, or ammunition cans that sit on shelves.
The introduction to Enphase’s products is very enlightening. I encourage Expat to go read. I found the technological … Continue reading
Hi Mr. Rawles,
I just ran across your site and have been browsing it. Your Precepts of Survivalist Philosophy are superb. Best is that you are a 100% sold out Christian.
You may find a few observations of interest, from one who has lived extensively off the grid. First, some background. I grew up in a tiny community with the surf out my front door and a thousand-year-old forest that stretched for miles in back. My father grew up on a homestead and trapline among the Sarcees of the Alberta Rocky Mountain foothills. He never had a pair of shoes on until twelve, only Sarcee moccasins. My mother was raised in a sod-house and half dugout on the New Mexico plains, when Pancho Villa was raiding nearby. With such parents to form my youth, when in 1963 my employer left me with no food for ten days on my first … Continue reading
I must confess that I haven’t had a chance to read every single post on “Making a Final Run”. A farm in winter can be a very busy place. So I hope I’m not just repeating someone else.
In the main I agree with most posters, a final run is possibly/probably not a good idea, maybe.
If you’re talking about a last run to Walmart, then maybe you run the chance of getting into the middle of where you don’t want to be. However, there are lots of other sorts of “final runs”, such as to the bank, the gas station, the feed store, and others. How safe a final run is can depend on how fast, prepared, and organized you are, and what particular goal you have in mind.
When 911 happened, I was in the barn working on something. When the news about the first tower came over … Continue reading
