Manual Gearbox Lubricants - Interesting Statement

The following statement was made in a lubrication newsletter I received today:

Quote:

In gear contacts, low surface roughness and thin oil films produce much less wear than high surface roughness and thick oil films. Properly "running in" a new gear unit can play a critical role in reducing surface roughness.

Oil film thickness is a function, among other things, of the lubricant's viscosity. The statement that a thinner oil film (read, lower viscosity) results in much less wear on the gear contact surfaces is interesting and generally counterintuitive for most of us.
