3.A: Alabama

Alabama has one gasoline quality standard, and it is a conventional gasoline. Quality parameters and limits, as set in the state’s Department of Agriculture & Industry regulations, largely conform to ASTM D4814 Standard Specification for Spark-Ignition Engine Fuel. Although the regulations adopt ASTM’s latest test methods by reference, they do not make any explicit reference to the ASTM D4814 standard itself.

The state’s limits for temperature at which the vapor-liquid ratio equals 20 (T@V/L=20) do deviate from the current ASTM standard, however. The state sets l
