While the additive package is unknown no name brand fuel, how important is it with direct injection? You can keep the injectors clean by fuel additives. You don't have to worry about deposits on the valves as the fuel never touches them to get in the cylinder. In many areas, it is the same fuel being sold, just the additive package is different. There are gasoline pipelines in many areas to get the fuel in. So all stations in that area are getting the fuel from the same place. So the only thing that they can do is change the additive package.
