i've run it exclusively in my current engine. Engine builder who ought to know said is great oil for break in or long term. Recommended (for flat tapppet cams) putting additional zddp in it as even rotella is lowering content. If you want to go synthetic go castrol syntech or mobile one (or amsoil too...).

V-Twin 1650 ppm ZDP
I think Rotell is now an SM oil and is down to 800ppm ZDP.
