Here are the UOA numbers of Shell Rotella T6 5w-40 for a 2012 Honda CBR1000RR. The oil spent one year in the engine (August, 2016 - August, 2017), and accumulated just over 5000 miles. Driving style was mixed between "normal" and spirited, and included one track day on this fill.
Here are the comments that were provided by Blackstone:
"Aluminum increased again, though this time it brought a little copper along for the ride. Aluminum
suggests piston wear (though it can come from transmission parts too, if the engine and transmission share
the oil), and copper suggests brass/bronze wear. Maybe some of this is accumulation from the longer oil
run, though we aren't totally sure that's the only thing going on. Cut back to about 3,000 miles on your next
interval and let's see how much metals settle down, then go from there. The thin viscosity is normal and the
0.5% fuel isn't a problem."
