## 1 Introduction  
In recent decades, the global community has expressed increasing concern about the growing number of pollutants emitted from the combustion of automotive fuels. The incomplete combustion of these fuels, which can result from engine malfunctions or the use of low-quality fuel, is a significant contributor to the generation of harmful pollutants that pose risks to the environment and human health. To ensure that automotive fuels meet appropriate quality standards, they must adhere to various legal requirements, including limits on the sulfur content, flash point, boiling point, and other quality parameters. During fuel combustion, sulfur combines with oxygen to form sulfur dioxide, which is released into the atmosphere along with carbon monoxide, carbon dioxide, and nitrogen oxides. Sulfur dioxide is a highly polluting substance that poses significant environmental and human health risks. The inhalation of sulfur dioxide can irritate the respiratory tract and contribute to the development or exacerbation of cardiovascular and respiratory diseases and cancer. Additionally, when sulfur dioxide interacts with water in the atmosphere, it forms sulfuric acid, the primary contributor to acid rain. Acid rain leads to environmental devastation, including the death of trees, changes in the pH of rivers and lakes, and soil contamination [1; 2; 3]. Generally, the oil and gas industry optimizes its processes to produce fuels with a mass fraction of sulfur that closely aligns with the specified requirements. This optimization necessitates meticulous decision-making when assessing the compliance with current legislation regarding potential environmental and human health harm. This rigorous approach ensures that the industry operates according to environmental regulations and prioritizes the well-being of the environment and human beings. Other quality and safety parameters inherent to fuels' physical and chemical properties, such as the flash and boiling points, must also be carefully monitored and controlled. These parameters can impact human safety and must be within specified limits to ensure the safe handling and use of fuels. The flash point of jet fuel refers to the minimum temperature at which it can ignite when exposed to an open flame. Jet fuel with a low flash point poses a significant fire hazard, as it has the potential for spontaneous ignition and explosion. This feature underscores the importance of ensuring that jet fuel has a sufficiently high flash point to mitigate the risk of fires [4]. The final boiling point of gasoline is the highest temperature reached during its distillation process. Variations in the distillation characteristics of gasoline can significantly impact various aspects of automotive performance, including engine start, acceleration, and the dilution of lubricant oil. Furthermore, these variations can also influence the fuel required during combustion. Significantly, a decrease in the final boiling point of gasoline leads to a decrease in the presence of heavier fuel components within the engine. This behavior indirectly contributes to a decrease in the production of pollutants during fuel combustion [5; 6]. Measurements of commercial petroleum products are carried out to determine whether they meet specifications. Specifications can be related to legal compliance, commercial requirements, or internal quality control [7]. In the real world, measurements of the same attribute in a particular sample using different test methods often yield slightly different results. As a result, test methods typically discuss result precision. This variability measure indicates the reliability of the measured property value. Often, challenges in interpreting specifications arise from the inherent imprecision in testing. Hence, it is not possible to determine a property's exact value; instead, we must rely on measured values to estimate the likely range in which the \"true value\" may exist. Data Reconciliation (DR) is a powerful tool that addresses this issue.
