Years ago I worked in and oil analysis laboratory with Page Industries,
at Ft. Rucker, AL. Page had the Aircraft Maintenance Contract there with
the Army  to maintain all their training aircraft and helicopters. At
 that time due to the Vietnam War hundreds of  Pilots were being put
through their paces in preparation to go to Vietnam. Thousands of
training hours were put on the helicoptors, and the Oil lab monitored
everything that had oil in it, especially transmissions that drove rotor
systems. Page also had a test program going where they hovered
helicopters in sand pits for hours, sucking sand into the engines, rotor
blades, everything. And the lab took samples from all the lube boxes and
tested, tested, tested. We go to where we were pretty good at predicting
a transmission failure. But the point of all this was that all those
transmissions, etc used synthetics for lubricant, not Dino oil.

So this sythetic lubs thing has been long in coming, and that kind of
testing proves the point. All of your jet aircraft tooday, use synthetic
lubricants due to their stability and protection from wear.
the technology has proven itself so far as synthetics are concerned.
Were it not for the fact I already have so many miles on my engine since
overhaul, I would switch to a synthetic oil for  it as well.
