Miscibility, water tolerance, cloud point, and flash point data are presented for seven candidate diesel fuel oxygenates: dipentyl ether, dibutoxymethane, 2-ethoxyethyl ether, diethyl maleate, tripropylene glycol monomethyl ether, dibutyl maleate, and glycerol tributrate. These oxygenates were blended with three different diesel fuels: an oil sands diesel, an ultra-low sulfur diesel, and a Fischer-Tropsch diesel. Blend levels included 0, 5, 10, 30, and 100 % oxygenate. Properties were measured at temperatures of -30, -15, 0, 15, and 30 C.
