Can one then assume that a thicker oil lube for the chain in the

summer is best? Perhaps motorcycle chain lube??

I can guess that with the colder temps, the thick oil can adhere to

the chain better giving it better lubrication throughout. Defiantly

food for thought.



I'd be surprised if a ~normal range of ambient air temperature is

significant in the context of friction generated heat at the critical

interface. Maybe in extremes...



Until I discover something better, I like Dumonde Tech year-round. It

lasts a *long* while in summer, and hangs in admirably in the rainy

season. It supposedly has chemical properties that *bond* to steel,

which sounds like advanced adherence, and the performance seems to

support something like this going on.





From their website...



"Dumonde Tech’s Liquid Grease is a high performance replacement for

traditional viscosity grease. Liquid Grease reduces the coefficient of

friction through Polymer Technology. Liquid Grease polymerizes and bonds

to the surface providing extremely low drag."



Hmmm. If it polymerizes, one would think that it (or a component of it)

goes on thin, polymerizes and becomes more viscous or wax like.



I believe the sulphur and other additives in EP oil chemically bond to

the steel surface - possibly with heat and pressure.



Not sure how the DT is supposed to bond, glue?



What is a bond after all?

FOOO....... bond is a word used to sell products, a word leading to a state not bonbing to definitions of fruad in advertizing.


bonding sulfur iznot bonnnnnding polymer that is to saaay sulfur iznot the lubricating property....NOT FROM HERE ANYWAYS ! good point.

http://en.wikipedia.org/wiki/Chemical_bond

an interesting tangent at the hip socket....recently in the news....we see a lubricating structure covering the supporting bone structure. Is the lubricating structure bonded to the bone structure ? No. Tho the two are of the same system, the two structures are seperable and distinctly different under a microscope or to the eye and off course, chemically.

to say the two - of anything really - to go out on a limb - are bonded is to say the two are one.

maybe the hyperlink is Party A ****ing on Party B ?

or are they in cahouts ?
