If you followed your dad's suggestion, I would consider that to be a way of cleaning the bearings...Not lubricanting them.
Tri-Flow is good for certain applications; but, has "formulated solvents" in it. You don't necessarily want to put both solvents AND oil into your bearings at the same time.
Trinity or Niftech oils would be my preferences for a lubricant.
Of course, I'm a dad too...And I'm always right...
But, you are the wise son who checks things too.
