So I'm new to the Corollas and I just purchased mine about 3 weeks ago. I filled up the tank twice but I noticed after filling up the tank I can hear the gas being thrown around. The first time noticing it I panicked and stopped at a parking lot to make sure gas wasn't leaking. It's not like I'm slamming on my brakes or coming to hard stop either. I'll come to a stop or begin driving and I hear the gas splashing around. Is this normal and am I the only one experiencing this? I've never owned a car where I heard that sound. I tried using the search to see if I could find a related post but found nothing. All inputs are appreciated. Thanks!
