      Spectro HD Platinum MC Oil

      This stuff is awesome, in addition to their 6-speed transmission fluid. Doesn’t look black/wornout after 5/10K miles. I use Spectro fluids in all three holes of my Ultra Limited. Good price and fast shipping at Lowbrow Customs. Will definitely purchase here again.
