[Hammarlund] Graphite is NOT an Abrasive...it is TOO!

[Kim Herron]

Hi Guys (and Gals),

       Let me interject something here on this discussion of various 
lubricant and things
that APPEAR to indicate a problem.  Your comparison of pure graphite in a 
gear train in a radio
used for lube, and the same product used in an internal combustion engine, 
fail to take one VERY important thing into consideration.  An engine is 
subjected to very high temps, produces various
combustion contaminants, that include acid and water, and these things find 
their way into the lube oil.  Most of the time, people who use these 
graphite based lubes or PTFE lubes DO NOT change their oil often enough to 
keep the crankcase flushed out, and the engine wears out because the acid 
build up that destroys the engine.  Mobile oil is currently paying for a 
bunch of engine overhauls in the aviation industry because their product 
cannot neutralize the acid in the oil in the plane engines and it's 
requiring cam and crank replacement due to acid etching.  I've seen the 
same thing in car engines for years.  There are many reasons why a lube my 
work in one application and not another,
and I could go on for a long time with various examples.  Our esteemed Mr. 
Ornitz matter correct
and I'll take his say on the matter.  As an aside, don't forget that the 
M-16 actions used in "Nam
liked that graphite a WHOLE lot better than the stuff that the military was 
using, or have you forgotten that flap?
