Most of the HD lubricants are made by Citgo Petroleum. None are very impressive compared to what you can by at Walmart or Autozone and I am very surprised still that HD ships its CVO bikes with 20w50 Syn3 in the gearbox. I used syn3 as a break-in oil on my TC88 and then went to M-1 Vtwin. Mobil1, Amsoil & Redline make better products for the same dollars IMO. But thousands of Harley guys still use the HD360 religiously and swear by it.
Somebody should tell them you can buy Mobil1 15w50 at Wallyworld for $1 less a quart...
