oil change question

[zooooom]

Does anyone use or add an oil flushing additive prior doing an oil change?
Or is it not recommended on dry sump engines.

I wouldn't, not all the oil can be drained from an S6 during the oil change!!!! so you would contaminate what is left in prior to new oil going in?

I think that flushing a dry sump engine is a big no-no, atleast not without considerable expertise.

Some of the guru's will be along shortly to throw some facts around..
