Pro-Blend is an amazing
oil additive. Been using it for 20 years in everything. Not a lubricant in itself, but bonds to the metal at a molecular level and the hotter the metal gets, the more it pulls the
oil to that spot.
Oil by itself "runs away" from hot spots on metal if normally left untreated. Everyone I know who uses it loves it.
They talk a lot about how much cooler the oil runs. This stuff is NOT an oil cooler. The fact that the oil runs cooler is a result of the huge reduction in friction it provides.
