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.

Unless the pump says ethanol free, all grades of gas will have ethanol and will varnish in months during summer- especially in the humid south.

You are much better off with plain ethanol free- usually sold as 89 octane.
