I have heard of using the same oil from motorcycle wetclutch setups. The only thing that I see a potential issue will be long term testing. Sure it will work for a while, but are there any changes in lifespan/other component failure. Depending on the viscosity of the oil, it is possible that it does not have the cooling capabilities (too thin) or it could be too thick and cause restriction of flow/cooling issues. Worst case it causes the pumps to burn up prematurely.
This is in the same ball park as what oil to run on supercharged setups. My long term testing 5+ years found that heavier 15-50/20-60 was the ideal oil for a supercharged VR6 or G60. The thinner oil like that used on 1.8T's caused premature bearing failure due to the lack of lubrication on the race surface. It also ran an average 20 deg hotter than the heavier oil.
Best bet might be to send it out and have the stock fluid examined to figure out the viscosity/chemical make up of the oil.
