So checking the gas cap it wasn't on tight, so I tried to figure out why, thinking maybe I just forgot. I found out that the gas cap on my car loosens very easily, I don't know why either... it comes off by barely unscrewing it. Maybe it wears too easily? Until it becomes a big issue I won't replace it.
my moms pt cruiser gas cap had same problem, $10 for a new locking cap
