I have never heard of sulfur being used as any sort of lubricant. How does this work? Does it just make a coating over the metal parts, or is it something more involved where the sulfur reacts with the metal to make it more resistant to wear and tear?
Also, do they make synthetic gear oil for cars and trucks? I know a lot of car enthusiasts argue about what type of motor oil they use in their engines. How does the quality of synthetic gear oil compare to natural oil?
