Abstract: An aeration system for fuel additives is used to aerate fuel additives prior to mixing with the fuel of a vehicle. In doing so, the overall effectiveness of the fuel additive may be improved. The system includes a bottle, a weighted block, an aerator, and an insertion tubing. The bottle is used to store a fuel additive and is mounted onto the weighted block. The weighted block is used to orient the bottle downwards so the fuel additive is able to pour out of the bottle. The aerator is used to aerate the fuel additive. The aerator is connected to the insertion tubing, which is used to transport the fuel additive to the tank of a vehicle. The system also includes a hanger which is used to position the bottle above the tank of a vehicle to ensure that the fuel additive flows into the tank of the vehicle.
