Oh, a clever jab; I must write that down!

The reason you have not heard from any "grease experts" is that depth of knowledge is superfluous for bicycles. One of the greatest virtues of bicycles are their relatively simple nature; they do not involve high temperature, high pressures, high speeds... all the things that require more performance from lubrications.

Many very knowledgable shops use automotive grease for very good reason; it's economical and it works well.

If you wish to complicate a non-complicated issues be my guest.
