Suppose you put 45 gallons of no ethanol unleaded in a barrell with the appropriate amount of stabalizer…… and a year and a half later you use 20 gallons of it. If you fill it back up with fresh gas does this “renew” what was in the barrell? Can you use out of it some and refill it indefinitely? Is there a point where the barrell should be completely emptied and refilled totally? I know some people here will know this answer. Thanks!
