A fuel or fuel blendstock for jet, gas turbine, rocket, and diesel engines, particularly jet, rocket, and diesel engines that utilizes components of conventional petroleum not currently utilized for jet, gas turbine, rocket, and diesel fuels, such as benzene, linear, and lightly branched alkanes, that may be alkylated with aromatic moieties to make monoaromatics for use in jet and diesel fuels. Additionally, a fuel having such monoaromatics having multiple desired properties such as higher flash point, low pour point, increased density, better lubricity, aerobic degradability, reduction in toxicity, and additionally can deliver benefits in blendstocks.
