I am replacing the speedometer cable on my 67 289 C4 fastback. I went to buy cable lubricant and was told it is no longer available since everything today is electronic. What can I use in it's place? I have a can of Silicone Spray, can I use that? If not, What
Johnpro suggested the following which works just fine. I used Marvel's Mystery Oil to lube the cable in my 65. I put the oil in a coffee can and let the cable soak in it for a while. Then I installed it. No more needle-jumping.
Graphite would be a good choice after the cable is cleaned of old gunk. Be aware it will be a very messy job especially with graphite powder, that stuff gets everywhere it ain't supposed to.
I have seen/used a teflon powder lubricant that comes in a small plastic tube with excellent results. It's much cleaner than graphite. That would be my choice. Trouble is I can't remember anything else about it.
If I should remember I'll post.
My 68 Mustang sitting in a bunch of boxes in my basement still looks better than your import!
few years ago i was looking for a lube to quite down a real nice squeel in a toyota truck speedo cable. found a small tube of lube at the local auto store that said it was good for speedo cables (that was in small print and didn't jump out at ya) . turned out to be some kind of liquid graphite stuff, i think that the graphite was only suspended in the liquid, that would later evaporate but that is only a guess. got ride of the squeeel and smoothed out the speedo needle as well.
