[TowerTalk] Mixing oils in HDX689

...and be sure to buy your super synthetic oil during the dark of the moon 
and pour it through a gold plated funnel using a minimum of 73.286% 
ultra-violet light of 340 nanometers wavelength to mitigate airborne 

Hey guys, it is super unlikely that anyone could measure a definitive 
difference in the wear of a rotor's lubricated parts when using dino-lube vs 
synthetic.  (Gasoline or diesel powered rotors excepted.) Rotors generate 
very little in the way of sulfur based acids or other deleterious compounds 
t associated with an ICE that need an additive package to maintain a 
reasonable service life.

How does one determine when to change oil?  Is it based on the cumulative 
distance communicated using antennas rotated by that rotor? Maybe a Hobbs 
meter (cumulative hours the motor is energized?) Do you take a sample and 
send it to the lab for analysis? Or do you use a Ouija board.  I have a low 
cost Ouija service offered to those who desire Ouija assistance in 
preventative maintenance but have no board of their own.

Magic incantations are more likely to produce superior results than 
synthetic lubricants in this application.  I'm good in QRZ.  Upon receipt of 
a money order or other form of negotiable  tender I will solemnly incant a 
proper incantation commensurate with the size of the stipend. Those opting 
for monthly incantations (varying in content and none recycled!) may pay 
quarterly AND those paying a year in advance will receive 2  B O N U S 
incantations between the winter solstice and the vernal equinox.

I also have connections with the Miraculous Mother Murphy, The Most Reverend 
Brother Ikrencoulter and a panoply of other  XERB potentates of a better 

I have NOMEX long johns so don't waste any energy flaming unless you have 
thermonuclear capabilities.

I belong to many auto and motorcycle reflectors, and it is always fun to 
kick off an “oil thread” there.
Never expected to get to do so on a tower/ham reflector!
