Default Drive Cable Lubrication

What do you guy's recommend for lubrication of C1 '59 speedometer tachometer and FI cables ?

Back in the 70's i used to be able to but a specific grease "Cable Lube" for this purpose. Can't find it anywhere.

So..... What are your thoughts, I've heard from people

1 PB Blaster Penetrating spray
2 Moly-Kote Grease
3 Brake Lube
4 Lithium grease
5 Pure Silicone

actually, I remember a graphite based lube as being recommended as it wouldn't migrate up the cable; but I reckon a lithium based multipurpose grease will work fine.

Bill, Thanks, The Graphite based stuff is what I used to get, I am afraid the Lithium might harden up with age and cause problems. My car is not driven that often although I try to get her out whenever possible and being in New England (mass) I need to cope with cold winter storage. Have you actually used it on your 62 ?

I would be more concerned about 'white' grease (lubriplate, etc) hardening, I wouldn't worry at all about a lithium general purpose grease

as to what I use, I honestly can't remember ever lubing it simply because it's a PIA to get out (but then I'm not sure what I had for breakfast anymore....); but I would use a lithium grease like I use in my grease gun for chassis lube.

For your FI pump cable use wheel bearing grease and keep in mind that too much is not enough. Seriously. Use more than you think is reasonable.

Napa also carries an excellent product called Sil-Glide which works well and is great for lots of other things also. Whatever lube you use, don't grease the last few inches near the cluster heads as it will migrate up some and you don't want ANY getting on the speedo or tach inside cups. Pilot Dan

Thanks for the advice Dan, Never thought of that being a problem but clearly your right.

I concur. Have you ever changed a FI cable by matchlight, at midnight?

Um, no, and that does not sound like a safe source of light!

And actually, in close to 40 years of driving with FI, I've never broken a cable (knock on wood or fiberglass). I do carry three spares, tho!

I have, and no spare...

I walked to a service station and we used a piece of copper tubing as a sleeve to solder the 2 pieces together; worked fine...

and, the cable will actually stay in place without the jacket...

This is true and, in the interest of full disclosure, I'll admit that I always run the cable bare on my fuelie. Never a problem.

However (you knew there had to be a "however" didn't you?), keep in mind that if you do any wide open throttle operation with a bare cable, it will try to twist itself into a pretzel, like this:



The cable in the picture is spinning at 3500 RPM (engine equivalent to 7000 RPM) and the pump is operating at 200 PSI, the design maximum for Rochester FI.
