Here's a piece of information about gear oils and gearbox oils that
might be interesting. Originally posted here by Roger Garnett, from
notes taken by Jack Poller at an engine building class when the
rep from RedLine Lubricants showed up to give a talk.
Gear Oil- excerpt from Jack L. Poller's notes at a redline seminar.
If anyone has full specs, Lets hear 'em.
------------------
Gear oil viscosity is measured at 150 F vs. 210 F for motor oil.
Therefore, 40 W motor oil is the same as 95 W gear oil.
Gear oil is acidic, motor oil is alkiline. Gear oil needs very high
wear protoection - Extreme Pressure (marked as EP). Therefore, it
has a very high sulfer and phospor content. Sulfur and Phosphate
reactions start at a lower temperature, and Gear Oil has much more
additive than motor oil. This additive is corrosive to copper
bearings and bronze synchro rings.
---------end of included message-----------
If sulfur and phosphate are typically used in the dispersants/detergents in
motor oil, there's the culprit. I think I'll make a point to change the
tranny oil in all my cars, oh, Saturday. :-)
