I stopped to pick up a couple filters yesterday and saw where the QS HM oil is SJ rated .
SJ oils typically had larger amounts of Phos and Zinc and of all the other HM oils out there this one stands out as the only SJ rated one .
Just a heads up for those wanting more Zinc than the typical SL oils that are nearing the 700 ppm area in terms of quanity if the around 1100 ppm of the other HM oils is not enough for you
