Quoted:
I keep 50 gallons on hand in 5s and it is cycle it once a year. I get Chevron premium and it gets Stable.
I have no reason to fuss about Chevron gas
It gets Stable under the assumption that I'll need to store it for quite some time.
You are free to do as you wish.
But
When a guy that says he works in a gasoline test lab says the keep gas 2 years in airtight containers.
Then another guy that says things tells me he works close to the gasoline test lab says use airtight containers.
Then TaylorWSO points out that Stabil has a shelf life.
EXPY37 has pointed out the basic ingredients of Stabil
CJan_NH has posted that the container is more important than the additive.
I guess I just see that the money I save by not buying Stabil allows more money for other things like more good jerry cans.
