Funny thing happened at the Harley dealership today. Stopped in to get a complete fluid change kit for my 2019 tri glide. I have always run syn3 in the crankcase, HD heavy duty 80-140 gear oil in the trans, and Formula+ in the primary, since first oil change in 2019. The parts counter guy refused to sell me the qt of Formula+ saying that Harley is now recommending the heavy duty gear oil for the primary. I got mad and finally got him to sell me a qt. Does anybody know if this is now true even though my manual says to use Formula+? He seemed to be a part of the service mgmt team and seemed knowledgable. Would rather stick with and use what seems to work. Any thoughts?
