520			_aThis study aims to address significant gaps in understanding the storage, handling management, and compliance with standards of E10 gasoline-ethanol blends, which is essential for its effective and sustainable implementation as an alternative fuel. Conducted within the fuel stations of Laoag City, Ilocos Norte, and assessed at the National Bioenergy Research and Innovation Center in Mariano Marcos State University, Batac Campus, this research employs a descriptive analysis to summarize results, qualitative methods to identify factors affecting E10 quality, and quasi experimental methods to establish cause-effect relationships between storage/handling practices and E10 quality. Out of 41 gas stations, only 10 were selected to undergo assessment using a cluster sampling method. The assessment utilized the PNS/DOE QS 008:2018 standards, referencing ASTM methods for testing physical and chemical properties to ensure compliance. The findings from the assessment of the physical and chemical properties of E10 blends revealed that all gas stations did not meet all the required standards. An example was the water content of E10 blends, which exhibited excessive water levels. A single non-compliant property indicated overall non compliance since even one property could cause a significant impact on the quality and reliability of fuel in terms of engine longevity and performance. For the interview, findings revealed variations in these practices, including differences in refill frequencies and testing approaches. Some stations employed in-house chemists or relied on accredited agencies for testing, while storage tank materials and maintenance practices also varied. Measures to prevent contamination, such as using water finder paste and conducting regular maintenance checks, were observed. The concept of “generic” fuels was introduced, indicating the need for further validation to determine its presence.
