I have three 5-gallon gas cans and wanted to see if I could store fuel for 5 years and still be able to use it. In order to maximize my efforts, I filled the cans with clear gas (non-ethanol) and treated them with Pri-G. There are two dosage levels of the Pri-G product I used: 1/2 oz per 1.25 gallons to preserve good fuel, and 1 oz. per 1.25 gallons to bring bad fuel back to life. Since I intended for this to sit at least 5 years before use, I added the double dose, 4 oz. total in each 5-gallon can, even though my fuel was new.
Fast forward approximately 6 years. I wanted to test the fuel and rotate it to be sure I have a good backup supply, so I gave it the smell test and, once passed, put 5 gallons in my pickup which already had about 15 gallons in the tank. Driving it indicated no ill effects, so I dumped the other 10 gallons in and it ran no differently than it ever has. After my experience, I can confidently state that gasoline can be safely stored for 6 years or more if using clear gas, and adding a good dose of Pri-G.
