There is an old term here in the UK, "Jack of all trades, Master of none", that in my opinion is HD Syn 3, I remember years ago asking my HD dealer if I could use a friction reducer in the HD mineral oil that my bike used at the time and was told "No, if you do that, the rollers in the crank bearings will not roll but slide" my answer was well if there is no friction, whats the difference, he did`nt have an answer for that.
Also why would you put the same oil in all 3 holes, if you get leak you have no idea where to start looking!
I agree with a previous reply, its unlikely the oil caused the problems, but it certainly did not help.
Hope the damage is not too serious and you get back on the road ASAP.
