I still use lube with carbide mandrels. Why wouldn't you use this simple step to help increase consistency?
However, I can't say that I have ever tried it without lube, so perhaps it isn't helping anything. To me, it is easy enough to do, that I kept using lube, even after changing to carbide mandrels.
