Just avoid that gas station. If you see a big tanker truck delivering gas to a station, do not get gas or go to another gas station; most likely dirt and sludge is being stirred up and you don't want any in your tank.

I had same problems with shell and mobil. I have always used sunoco but couple of times I was in a rush and didnt have time to look for sunoco. Sunoco all the way!

Make sure your gas cap is on tight after filling up. If it happens each time after you fill up, maybe it's not the gas but the the seal on your gas cap.
