People use it as a backup fuel source for generators, while others prepare for potential disasters. The latter is very popular in the survivalist community, storing different types of necessary supplies such as food and water. In this case, gasoline is used to power up vehicles that you can use once out of your safe zone.

What are the best types of gasoline to be stored?

There are two types of gas that can be stored safely and properly: Leaded Gasoline and Unleaded Gasoline.

Leaded gasoline

Leaded has to be used for vintage cars, while unleaded can be used for modern cars or motorcycles, boats, chainsaws, etc.

The main difference between these two types is the Zinc additive in leaded gasoline which acts as a de-carbonize, allowing for easier starts when cold.

Another important distinction about leaded gas is that it comes with higher octane ratings than unleaded, so vehicles requiring high octane fuel can only run on this type of gasoline.

Unleaded gasoline

Since unleaded doesn't contain the de-carbonizing additive of led, it is advisable to use this type for modern engines or cars that need low octane ratings. If you choose this type, you may store your gas for two years.

For even longer storage times, you can always mix the two types and use a blender unit to ensure the property and ratios of the mixture remain the same.

Finally, it is important to note that leaded gasoline provides better lubrication than unleaded gas for older vehicles. If you want to store your gas for more than five months, then stored unleaded gasoline should be treated with a stabilizer to prevent gumming up of the fuel system.

How To Store Gasoline For A Long Period Of Time?

If you're planning to store gasoline for a long time, consider the following ten tips and tricks from automotive experts:

1. Add a fuel stabilizer to gasoline when it's time for storage

Even if you are only storing your gas for a couple of weeks, you should still add a gas stabilizer to protect your fuel system.

Gasoline that sits for even just a month can begin to oxidize and corrode the fuel lines leading to dead ends.

To prevent this from occurring, use an additive like STA-BIL or Stabil, which will allow you to store up to 12 months without the risk of gummy residue or clogging filters.

2. Keep gas cans in a cool, dry place if you plan to store gasoline for a long time

If your gas containers are exposed to heat, direct sunlight, and humidity, then the quality of your fuel would be compromised.

To avoid this issue, keep your containers sealed until just before use inside a separate location that is not exposed to excessive heat or moisture over extended periods.

3. Only buy as much gasoline at one time as you can store properly for longer periods

If possible, purchase only what you think you will have enough storage capacity for since it's better to have too little than too much, which could lead to slipping up on your own rules.

4. Store gasoline in a cool and dark location

Exposure to extreme temperatures can cause varnish build-up or worsen existing problems, so always store your gas properly to prevent potential issues from occurring.

If you'll be using containers with spouts for draining and filling, make sure they're sealed tightly and stored separately from the cans themselves. The same goes for any other equipment that could contact the fuel, such as funnels or filters.

5. Transfer gasoline into air-tight containers once it's been stabilized

Transferring less than 1/8 of a gallon at a time will help minimize air exposure, leading to reduced shelf life.

It is also important to use only approved containers to store your gasoline.

6. Store fuel additives properly

Since additives are used during the mixing process, you need to ensure they are stored separately from the actual gasoline, or it becomes less effective over time.

7. Don't use old containers for storing gasoline since there's no telling how long it has been sitting around

If storing gas in cans, make sure their lids are not rusted or loose and that the paint isn't chipping off. If using plastic bottles, check them thoroughly for any punctures or leaks before transferring fuel into them.

8. Always pour instead of siphon when adding fuel into a container

Siphoning can introduce water vapor is bad for storage since it leads to rust and corrosion of the engine compartment.

9. Add a fuel stabilizer before storing gasoline for more than five months

Since gas breaks down over time, it's important to add a stabilizer such as Sta-Bil at least every five months if you won't use your vehicle often enough.

10. Store gasoline in containers with wider spouts instead of ones that have very narrow openings

Narrow openings might clog up after long periods of use, and no one wants that, especially when you need gas stored in them ASAP.
