At SouthBay Fuel Injectors, we prioritize accuracy and precision in our testing procedures. To ensure reliable results, we use only the best calibration fluid in all of our test equipment. This calibration fluid is carefully selected to closely mimic the properties of gasoline without actually using gasoline itself.

Specific gravity is an important measurement used in our testing process. It refers to the ratio of the density of a substance to the density (mass of the same unit volume) of a reference substance. In our case, the reference substance is gasoline. By comparing the specific gravity of the calibration fluid to that of gasoline, we can accurately assess the performance of the fuel injectors.
