I don't let my gas gauge go any lower than 3 quaters of a tank low sometimes half a tank. That way it doesnt cost as much to fill up and i use less gas. I was just wondering if the gas thats staying in there is being used wich it should be because its getting mixed in with the new gas. So every once in a while do i need to let it get down to empty to fill the tank back up with fresh gas or will it be fine just to keep doing what im doing. in other words is it going to effect my vehicle in the long run?
