I have a 5 gallon can of gas from 8 months ago. I did far less yard work than I intended. I have fuel additives I could use. Joogle says 3-6 months, but I am looking for "real world" answers.

Please only answer if you know what you are talking about, and remember, I already used the internet to try to find my own answers.

Edited: Fuel is 89 Octane with UP TO 10% ethanol added.

I have been storing 100 gallons of 87 octane in 5 gal Nato military cans for about 8 years now. I rotate my fuel every 12 -16 months with no problems. (Stored inside with temps between 50-90 degrees)
