Do different companies make better quality gas than others?

When I fill up at a gas station, I always calculate my mileage for the trip. I’ve noticed that when I fill up from places like Chevron on Costco, my gas mileage is way better than places like Cenex. What are some good companies with good gas and some with bad?

They all share and use the same base gasoline stock, the difference is in the additives.

some sell off season fuel for cheap

chevron gives better mpg because it has techron fuel cleaner in it


I would rather run my engine on gasoline then cleaner
