I've used a lot of it as well. If you have any be sure it's the clear slightly cloudy stuff and not the paint like white paste heat transfer compound. That paste uses a "pigment" of some powder with a lower heat conduction coefficient. It's likely not going to be the best for lubricating. The clear or slightly cloudy silicone grease that was more common way back when is just grease with no fillers. That's what would work better.
