Storage stability of federal specification gasoline
Technical Report
·
OSTI ID:6158475
Eight drum samples of gasoline from various petroleum companies representing fuels meeting the requirements of Federal Specification VV-G-001690 (Army MR) Gasoline, Automotive, Low Lead or Unleaded, and four drums of European gasolines meeting the requirements of Federal Specification VV-G-76B, Gasoline Automotive, were stored for six months in sealed drums under cover at ambient conditions. Two of the VV-G-001690 gasolines were unleaded and six were low lead fuels. Analyses, bench and engine tests performed on these samples, prior to and after the storage period, indicated that gasolines meeting federal specification requirements have adequate storage stability for at least six months and probably for longer periods. Gasolines with high olefin content appeared to have less storage stability than those with lower olefin content. The work indicates that, from the standpoint of storage stability, combat gasoline in the military system could be replaced with federal specification gasoline with no adverse effects; however, a more severe oxidation stability requirement should be included in the Federal Specifications to insure adequate storage stability.
