WHY ARE THE GAS TANKS ROTTING OUT WHEN YEARS AGO GAS TANKS LASTED A LIFETIME AND MORE. EITHER THE GAS HAS AN ADDATIVE THAT IS DOING IT OR THE MFGS' OF GAS TANKS ARE USING POOR QUALITY MATERIALS. THESE LEAKS START AS PIN HOLES AND THEN GROW SO MILLIONS COULD BE DUMPING GASOLINE ALL OF OUR ROADS THAT IS FINDING ITS WAY INTO OUR AIR AND WATER. THIS PROBLEM IS AS SERIOUS AS THE GAS STATION TANKS OF YEARS AGO AND FOR SOME REASON IT IS GOING BY UNNOTICED. I WOULD LIKE A RESPONSE TO THIS COMPLAINT. MY COMPLAINT HAS ALSO BEEN REPORTED TO THE EPA. *AK
