Pull a sample of fuel out of the tank. If it's not clear, then your getting oil in the fuel. Could be a number of things. Cracked cyl head, bad injector o-rings, or bad injectors. I've never worked on a 7.3, but on CAT 3126's(HEUI) with high oil consumption it's almost always the injectors at fault.
