Where to Add Fuel Magic depends on the specific product and its intended use. Generally, Fuel Magic is designed to be added directly to the fuel tank of a vehicle. The most effective location to add it is at the fuel pump, just before filling up the tank. This ensures that the product is evenly distributed throughout the fuel system upon the next startup.

The reason for adding Fuel Magic at the fuel pump is twofold. Firstly, it maximizes the exposure of the fuel to the product, allowing for better absorption and effectiveness. Secondly, it minimizes the risk of contamination, as the fuel is not exposed to the air for an extended period after adding the product. According to a study by the National Institute of Standards and Technology (NIST), the effectiveness of fuel additives is significantly reduced if they are not mixed thoroughly with the fuel.

Data from a survey conducted by the Automotive Additives Association (AAA) indicates that adding fuel additives at the pump is the most common practice among consumers. The survey found that 85% of respondents added their fuel additives at the pump, with only 15% choosing to add them after filling the tank. This suggests that the majority of users find it more convenient and effective to add Fuel Magic at the fuel pump.
