equivalent for liquefied petroleum gas shall be an energy equivalent rate equal to seventy-three percent of the state tax per gallon on gasoline and diesel fuel which shall be the unit of
measurement for purposes of the tax levied pursuant to the provisions of this Section if the

order for the taxes due on the fuel to be paid by the motor vehicle operator. However, the
amount of the tax for issuance of the decal shall be calculated at a rate of one-twelfth of the
total annual tax amount for each month the decal is valid.
