WD-40 was designed to be water dispersant, hence the WD in its name. Its intended use is not as a lubricant, though it has some lubricating qualities. It will not remain stable, and will likely cause problems later. A tiny amount of One-Lube could be okay, and I have used 0W-10 synthetic motor oil successfully on delicate mechanisms. Don't use silicone, especially CRC silicone lubricant, which has very aggressive solvents which will damage paint or plastic.
