Here is how I lube them, even if they are so rusted they barely move.
Clamp a hose over the top of the outside of the cable. Fill the hose with transmission fluid or what ever you want to use. Then put compressed air to the hose. If the cable is in really bad shape clamp the air gun to the hose and clamp the handle down. If you leave 100 psi on it over night and the oil doesn't come through its time to buy a new cable. Use common sense, dont blow the hose up.
