Anything that reduces heat helps. Where bearings are concerned, it is the damage
to the oil that the heat causes that results in increased wear. Lube oils are
molecular chains and high heat speeds the breaking of these little chains. Then
the shear-strength of the oil is reduced, and the parts wear faster. This is why
recycled oil is always suspect. You can't repair the long chain molecules.
