Fuel Storage and Stabilizers: Keep Your Generator Ready for Any Emergency

June 23, 2026

A generator is only useful if it starts when you need it. And the most common reason generators fail during an emergency is stale, degraded fuel. Gasoline begins breaking down within 30–90 days of storage, leaving behind varnish and gum deposits that clog carburetors and fuel injectors. With a proper fuel stabilizer, you can extend that window to 2 years or more.

Why Gasoline Degrades

Modern gasoline contains ethanol (up to 10% in standard fuel) that attracts and absorbs water vapor. This water absorption causes phase separation — where ethanol and water settle to the bottom of your tank or container, leaving a layer of fuel-ethanol-water that won't combust cleanly. The result: a generator that cranks but won't run, or runs poorly and damages itself.

Beyond ethanol issues, gasoline oxidizes on contact with air. Oxygen reacts with the lighter hydrocarbon fractions, creating peroxides that further break down into varnish.

How Fuel Stabilizers Work

High-quality fuel stabilizers like PRI-G work through two mechanisms:

Antioxidants: Scavenge free oxygen radicals before they can react with the fuel
Fuel chemistry restoration: Unlike simple preservative stabilizers, PRI-G actually rejuvenates degraded fuel — bringing old gasoline back to near-fresh condition in many cases

PRI-G vs. Standard Stabilizers

Most hardware store stabilizers (like STA-BIL) simply slow degradation. PRI-G is a more advanced treatment that can extend fuel life up to 2+ years and, critically, can restore already-degraded fuel to usability. For serious emergency preparedness, PRI-G is the professional-grade choice.

👉 PRI-G Gasoline Treatment – 32 oz (treats up to 256 gallons)

👉 PRI-D Diesel Fuel Stabilizer – Gallon Size (treats up to 2,000 gallons of diesel)

Safe Fuel Storage Guidelines

Use approved containers: HDPE fuel-rated containers only (red for gasoline, yellow for diesel)
Storage location: Outside your living space, in a detached garage or shed, away from ignition sources
Temperature: Avoid extreme heat — fuel in a hot vehicle expands and can leak
Rotation: Even with stabilizer, rotate stored fuel every 12–24 months. Use it in your vehicles and replace with fresh treated fuel.
Label: Write the storage date and treatment date on each container

How Much Fuel to Store

Calculate based on your generator's consumption rate (listed in the manual as gallons per hour at load) and your expected runtime:

Gallons = (hours per day) × (gal/hr at load) × (days of backup)
Example: 8 hr/day × 0.75 gal/hr × 7 days = 42 gallons for one week

Don't Forget Diesel

Diesel is actually more stable than gasoline but still degrades. For diesel generators or vehicles, PRI-D provides the same restoration and preservation benefits.

Excellent Mill

I received a kindly email saying that an unexpected delay in shipping occurred, but that the order would be fulfilled at the earliest possible time. It would've been helpful to have been given tracking information so that I could have some idea when it might arrive and so leave my gate open.
As it happened, the package was delivered unexpectedly and left outside of the gate. The mill was packaged reasonably well, although the temporary, transport-security base was broken. All of the iron parts were undamaged.
The assembly instructions do not exactly correspond to the model I received, but it was not too difficult to figure out.
As with most metallic items that come into contact with food, I believed that those surfaces should be cleaned with mild soap and warm water before use. However it is not easy to remove the center shaft. I used a rubber mallet to drive out the shaft, the spring augur, and bearings.
After washing, drying, and re-assembly, a test grind produced nice flour, although not as fine a grind as I have gotten with hand-operated stone mills.
The advantage of this mill is easy cleaning of the grind plates and no stone particles in the flour. Also, the mill is nicely heavy and easy to operate, and can be belt driven with a slow-enough electric motor. Step-down gearing could also be used, if necessary.
A suggestion would be to include an exploded-view diagram, showing all of the clearly named parts.
The Owner's Manual makes no mention of it, but replacement parts *might* be available if they are asked for through the chat feature on the SafeCastle website.

Starts cooking as soon as you apply. heat. Cooks real easy in microwave no stove required.

Every bit as good as store bought hamburger meat

The can arrived well packaged & w/ no dents. My wife used the canned ground beef to make beef stroganoff. The result was excellent & every bit as good as store bought hamburger meat. It's just plain ground beef w/ no spices or flavorings added. We liked that because we could flavor it to our taste. Thank you.
