Not all machine oils are created equal.

The above link is for one fluid ounce (30ml) of industrial machine oil. For laserdisc players and other precision electronics, you need an oil with high lubricity and low viscosity. This machine oil is exceptionally lightweight making it perfectly suited for lubricating optics rails and other precision components in laserdisc players where low resistance is necessary. The needle-tipped applicator bottle allows you to flip the bottle upside down without leaking oil. A gentle squeeze will dispense as little as one drop at a time allowing for precise application.

Not all grease is created equal.

The above link is for approximately .35 fl. oz. of white lithium grease specifically formulated for use in electronics. For laserdisc players and other precision electronics, you need a grease with high lubricity that remains soft and clings well. This lithium grease is excellent for lubricating gears, tracks, and other precision components in laserdisc players where low resistance is necessary. Included are 2 precision applicators which are useful both in removing old grease and applying new grease without making a mess.
