Water In Your Gas Tank Is Major Trouble This is not something you hear about often, but when it happens, it means major issues for your vehicle. I am talking about when water gets into your gas tank. According to our news partners at KATC-TV 3, a Mobile station on Verot School Road had an issue with the cap on a tank, and the result was water in the gas. The President of Lard Oil Company, Johnny Milazzo, told the station it was a matter where the cap wasn't tight enough. He added they addressed the issue right away, and they are working with those impacted by what happened.
