I've never tried it in a AHU, but I run various mixes of used motor oil, hydraulic/brake fluid, and transmission oil, as well as raw gas (mixed in, except that one time) in my Golf D. It hasn't damaged anything yet, and I know people that have been doing it for as long as they've owned their cars with no perceptible issues.
I rarely buy highway diesel for my truck or the Golf. Well, I don't buy anything for the Golf anymore, it's sitting on stands waiting for the engine and cradle to be pulled.
