I've read on other boards that it would work better to use extra fine graphite to lube the speedo cable. So for the heck of it, I did it to my "other" car, the speedo cable is not as long, but it really worked well. I used brake cleaner to get the grease off the inside and the metal spring. The motion of the speedo on my "other" car was smooth and gradual.
I would recommend to anyone else that wants lots of lubrication in all areas of the cable.
