Im trying to figure out why everyone wants these higher weight oils for 
their cars.  If Audi recommends a 10w30, they mean it.  There are a 
million things to consider with picking the weight of the oil.  If you go 
to thin, then there is too much metal to metal contact as the shear 
stress is too high and the film can be penetrated, onthe other hand, if 
the oil is too thick, it wont reach certain areas quick enough, if at 
all, and it causes alot more internal friction and power loss as well.

IMO, use the recommended weight, the manufacture is best able to 
determine the tolerances of everything in the engine and pick a weight 
that will work best for everything....
