Yes, ALWAYS prime the turbo with oil. But....
Forgive me if I am off base but isn't it about heat cycling, not just driving it easy for 100, 200, etc. miles? I was under the impression that you want it to heat up fully, cool fully, heat up, and cool a reasonable number of times to allow for the expansion and contraction of the metal and seating of parts and seals before you spin the shaft over 9000+ (arbitrary #) times.
Discuss?
