I just wanted to clarify one thing. When I said "thicker" I should have noted that the additive makes the oil more resilient to heat and wear. The oil become tougher during hard, hot work. Slick50 and others actually help during the cold winter months by making the oil more fluid and able to build pressure when regular oil would take a while to flow.
