Abstract : Various fuel system materials including elastomers, structural adhesives, and tank coatings were subjected to accelerated agings in both petroleum produced and shale oil produced JP-4 fuels. Comparisons were made of the test results in the different fuels. There was no significant difference in the test results for most materials. There was, however, significantly more deterioration of buna N and polyurethane elastomers in shale oil JP-4 than in petroleum derived JP-4. Repeat tests in a second supply of shale oil JP-4 did not result in the buna N and polyurethane deterioration. The results indicate that the first batch of shale oil JP-4 was contaminated although the contaminant could not be identified. Subsequent testing will be done with future batches of shale oil JP-4 to insure there is not a problem.
