Gas tanks are designed so that when the filling station pump detects a full tank, and cuts-off automatically, there is still an air space at the top of the tank.

This is to allow for expansion of the fuel due to temperature changes.

Therefore do not trickle fill, or use any other technique, to get the maximum amount of fuel into tank. If you are successful in eliminating the air space you could create a leak. ie. Fill with cold fuel, then drive to a parking lot in full sunshine - the fuel will expand and force its way out through tank vent or some other place.

Gas will bubble back when filling the tank if the gas is going in too fast. In most filler tubes for newer vehicles, there is a mechanism that prevents siphoning. If the gas gets trapped in this mechanism, it cannot handle the volume and it might spit some of it back.

Drain the gas tank, there is a plug under the tank...unscrew and drain all of the fuel out. Screw the plug back in. Have the vehicle towed to the nearest gas station. Unscrew gas cap. Fill the gas tank with premium gas only. Keep filling after the the pump clicks....you want to make sure you get your moneys worth but dont let it over flow. Tighten gas cap until it clicks. Go inside the store and tell the clerk that you just found out how much gas your tank holds!
