Good synthetic grease, or alot of people seal the lower case with some silicone and run some gear oil, or oil stabilizer. Just enough to have the lowest teeth submerged on the bottom gear, when they spin it will coat the gears evenly and not cause too much drag. Friction causes wear and some sort of lubricant will help cut down on the friction.
