How Long Does Diesel Last?
Gas vs. Propane Generator
Gas powered and propane generators are both great sources of power during a blackout or when camping. While propane-powered generators are more cost-effective in the long run, gas-powered generators usually have a lower initial cost. These are a few points of difference between the two:
You probably won’t need your generator every day. This means you may need to store it for most of the time. Propane is a far superior fuel when it comes to shelf life. Gasoline is highly flammable and generally degrades after a year. Moreover, propane doesn’t degrade with time like natural gas.
The only drawback to propane is that it is a hazardous material and needs to be stored in a certified storage tank or cylinder. The best propane generators require timely maintenance. In fact, propane cylinders need to be recertified every 10 years. Bulk storage should be reassessed every 25 years. Gasoline leaves carbon deposits that can degrade the shelf life of your generator.
Another chief drawback of propane-powered generators is that these can be difficult to repair in a DIY setup. Gas-powered generators have far easier mechanics as compared to propane generators. Propane-powered generators are notorious for having complicated mechanics that don’t leave room for operating errors.
Gasoline is easily accessible during an emergency. You can simply siphon off a little bit from your car when there are no other available sources. You will need to get a bulk tank if you are using a propane fueled generator.
Gas generators are more efficient as compared to propane generators. Stemming from this, propane generators are more environmentally friendly. These generators produce a lower amount of carbon monoxide in comparison. In fact, they release half the amount of carbon monoxide as compared to a gasoline generator.
How to Store Gasoline Long Term
You need to follow simple rules for safety and effectiveness if you want to keep a stash of fuel at your bug-out location or at home. It’s critical to obtain suitable containers. Plastic containers are terrific for storing gasoline for long term. Most modern plastic containers available in supermarkets can be used for storing gasoline. Diesel is usually kept in yellow containers while red is used for gasoline.
If you need more than a few gallons, you should purchase barrels. However, make sure you never mix gasoline barrels with other types of fuel. Farm supply stores and racing shops are great places for purchasing barrels. You can get a small 30-gallon drum or a standard 55-gallong drum quite readily. Drums are ideal, but they are not without a few inherent issues.
You should make sure the drums are completely dry before you fill them. Make sure to seal them tight until you decide to use the fuel. Always store gasoline in a cool and dry place. It needs to remain cool, fresh, and depressurized. This is especially important if you are storing dozens of gallons of highly flammable fuel. Leaving a tank of fuel in the hot sun can be hazardous.
You should keep the fuel tanks stored in a shed or garage. Make sure it’s a well-ventilated area. You should also ensure the tanks are not kept in direct sunlight. Keep them away from your vehicles’ exhaust pipes, space heaters, and other sources of heat. You should inspect the storage tanks regularly for pressurization. Remove the cap carefully and let the fumes escape if the tank appears to be ballooning with gas fumes.

How Long Does Diesel Last?
Diesel fuel does not have an infinite shelf life. You cannot use contaminated or expired fuel. Most generators experience engine damage or premature shutdown. Diesel fuel is usually designed to last for only 28 days. There is a demand for low-sulfur diesel that is more prone to contamination. Gas stations are not equipped to store fuel that is less resistant to bacteria growth.
You can use water controllers, biocides, stabilizers, and other additives to extend the shelf life of diesel fuel. Most facilities have their supply tested periodically for ensuring its viability. You should always purchase diesel fuel that hasn’t been stored for a long period of time. The three main threats to the quality of fuel when above conditions are not met are microbial growth, hydrolysis, and oxidation.
These three factors can easily shorten the lifespan of diesel. In fact, the quality of the diesel can quickly degrade after just 6 months. This can be a problem if you have tri fuel generators or a dual fuel technology generator. There are steps that you can take to delay oxidation. For instance, you can use a cool gas tank. 20°F is the ideal temperature for storing diesel.
In any case, the temperature should never exceed 85°F whether you are storing gasoline or diesel. You can invest in an underground tank or provide a canopy to achieve cooler temperatures. You should not use fuel additives or treatment that claim to be useful for treating both diesel and gasoline. The additive you use for treating diesel should be specific to diesel and not any other fuel source.
