[R-390] Synthetic Oil

[Bill Guyger via R-390]

Guys as long as we're talking synthetic oil, Royal Purple is a great lube for many things, I think the gear train would be ideal as long as you use something light like 5W-30. The armorers for the Dallas PD recommend it for gun use since it stands up to high temperatures. A quart bottle was a lot cheaper in the long run than buying some of the marvelous, magical, miracle "snake oils" that work at the molecular level..........duh, all oil works at the molecular level. They lubricate by forming mono molecular films, but don't let the general public know that, it'd put a lot of PR guys out of work.

FWIW the last time I was over at DFW Gun range, I noticed that Royal Purple is being sold in spray cans just for gun lubricant so that might be something to think about too.

Barry & All,

     Having been raised in a family of HVAC workers, I was taught early 
on that when lubing a "sleeve bearing" motor to always use 
non-detergent, as the detergent additive would "glaze" the sleeve 
bearing and cause premature wear. It did seem to work for heating 
circulators and  aqua boosters. Would this not apply to Mobil 1 , etc. 
??? Just asking
