I have a leak from the front of the engine bay. Liquid looks clear and feels like a low viscosity oil...it's not coolant, and doesn't smell like fuel. Leak's heavy and then quits after being driven. It's dripping from the passenger side.

 

Sounds like condensation from the AC drain.....

 

If it's near the firewall on the passenger side then it's water from evaporator box.
Otherwise it's either coolant or engine oil.

 

What makes you believe it isn't coolant?

I say this because the 06's have a very common coolant leak at the rubber coupling hose near the turbo area and the coolant feels like and looks like clean low viscosity oil.

 

Only liquid that is even remotely clear is the coolant. Or it's the AC evaporator dripping water. Your description of leaks heavy during driving then stops isn't very descriptive.
Youll need to go find where it's leaking from.
