I would question the validity of that tech's knowledge. Molybdenum disulfide was most certainly available back then! Why else would that very compound be specified in the SAE paper published in 1955?

It may be, however, common practice to flush out all old grease to avoid potential compatibility issues between different products.

I'm no chemist or engineer, but my gut tells me the product pages for which I posted links in the FAQ don't tell the whole story. So, I followed the links for the MSDS sheets, which show that ALL THREE products contain molybdenum disulfide - INCLUDING SL-3144. However, SL-3144 has quite a bit less of it than the other two products - might not be the best choice.

Too bad we don't know all the components and proportions of the original compensator grease.
