[TowerTalk] Rotator Lube

[Bob K6UJ]

I agree with Wayne.  The synthetic grease does not break down at higher 
temperatures
and maintains the same viscosity.  Avoid petroleum grease because it 
will break down and the viscosity
does change with the temperature.   I use Super Lube also. Great stuff.  
It is also good for putting on battery terminals and other electrical 
connections to seal against moisture.
Synthetic lubricants are superior to petroleum based lubricants whether 
it is grease or oil.
Not to drift too far away here but remember when Mobil One synthetic oil 
first came out ?
The petroleum oil providers were shaking in their boots.  Research 
revealed that Mobil One
was much superior to the petroleum based oils. Remember the landmark 
test of Mobil One vs petroleum
oil conducted in the mid 70's where a fleet of highway patrol cars were 
driven 12000 miles using Mobil One ?
They tested the Mobil One oil properties used in this test afterwards 
and it did not show any degradation at all.
At about the same time, Chevron tested Mobil One vs their petroleum 
based oil at their Research Lab for reducing wear.  They dismantled 
brand new engines and measured all the journals, recorded the data, 
reassembled the engines and ran the engines using Mobil One for the 
equivalent of 100,000 miles with dynamometers.  Then the engines were 
taken out and dismantled and all the journals were measured again for 
wear and the new measurements were compared for each journal.  It was a 
real eye opener.  There was very little wear, in fact very close to the 
measurements done initially.   Much less wear compared to when the same 
tests were done using their petroleum based oil.   In case you haven't 
figured it out I am a fan of synthetic
lubricants :-)    I recently replaced the gear lube with synthetic in 
the worm gear drive on my US Tower
motorized winch.    OK I am thru with my rant now.  Hope I didn't put 
anyone to sleep  :-)
