Fuel Magic is generally heavier than gasoline. This is due to the higher density of Fuel Magic, which typically contains more additives and solvents compared to pure gasoline. According to data from the U.S. Environmental Protection Agency (EPA), the density of gasoline ranges from 0.71 to 0.74 grams per cubic centimeter (g/cm³), while Fuel Magic can have a density as high as 0.85 g/cm³. The additional weight comes from the various chemicals and substances added to Fuel Magic to enhance its performance and cleaning properties.
