Yup. Me too.
The best time of the year to fill your containers with gasoline is in the dead of winter...the refineries add more butane during the winter months for easier starting in the cold.
It also depends on what you are trying to burn old gas in.
I had some five-year old stuff that was starting to get tiny specks of brown stuff in it, almost like a lacquer.
Dumped a couple gallons in my 66 Chev w/350 V8
No problem!
But I would never burn it in a small engine like a generator or a modern car with high-tech injectors, that’s just askin for trouble.
