Agree. The Rotella is not the cause of the clutch slipping. The 1164 cc ZRX isn't that magnificent V-Twin, but 87 ft/lbs and 145 horses at the rear wheel (in current form), it's within 13% of the Roadstar on torque, as I believe the stock Roadstar puts down about 100 ft/lbs at the wheel. The T5 15w40 syn blend doesn't have their JASO approval however I ran it and there were no issues, and it provided some of the best wear numbers of any of them. With that said I do like a better dose of zinc in my oil because the ZRX is known to need better lobe and tappet protection due to location of the oiling holes for the cam lobes.
I hope at the end of next riding season the aluminum numbers have come down, as there are now just over 10,000 miles on the new high comp pistons. For wear, everything else is really good.
