Specific gravity is used to classify and monitor what aspect of fuels?

Specific gravity measures how dense a fuel is compared with water. Because different fuels have characteristic densities, this ratio is used to classify fuel grades and to monitor fuel quality. A higher specific gravity means the fuel is denser per unit volume, while a lower value means it’s lighter. This helps verify that the right grade is present and can reveal issues like contamination or improper blending if the density shifts unexpectedly. Other properties—boiling point, flash point, or color—describe different aspects (vaporization, flammability, and appearance) and do not define density, so they’re not what specific gravity tracks.
