I have certainly heard of people getting bad tanks of fuel and water in their fuel but my personal experience has been never happened to me - and I have used a heck of a lot of cheap fuel over the years starting around 1979. I think it is one of those luck of the draw things there is no point in worrying about. Even the high priced fuel stops can have their problems. I guess I should knock on wood or something but my point is the odds seem to be that getting a bad tank is a very rare occurrence. We even use Bio-Diesel if they have it. If they would sell us off-road I would use that too. But I do change my fuel filters and I do always carry spares - so still not 100% confident.
