The storage stability characteristics of diesel fuels meeting the requirements of Federal Specification VV-F-800a Fuel Oil, Diesel were investigated by conducting a two-year storage program involving four different diesel fuels. The fuels, stored in 100 bbl. above-ground steel tanks located at Aberdeen Proving Ground, Maryland, were sampled at three levels each month for the first year and every third month during the second year. Specific tests were performed on each sample to assess the degree of fuel deterioration. At the termination of the two-year program, two of the fuels maintained satisfactory storage stability whereas one fuel exhibited a cyclic pattern typical of unsatisfactory storage stability. The fourth fuel was considered marginal with respect to storage stability since initially low values were evidenced followed by a gradual increase indicative of fuel instability. Author
