G1000 and GFC700 Servos - Maintenance on Ovation 3

[Healthpilot]

This is from the Garmin Manual: but how often does this need to be done? I found a non-Mooney specific version of this PDF that calls: grease on servos every 3 years or 1,000 hours. What do most of you guys do on Ovation 3 or other GFC700 autopilot G1000 equipped Mooney's? any other advice on maintenance of the autopilot systems?

"4.6 GSA 81 Greasing Procedure Re-grease each servo output gear following the procedure below: 1. Remove each servo. 2. Remove excess grease build-up from the single servo output gear using a lint-free cloth.     It is not necessary to remove all of the grease from the output gear, only the excess grease.  DO NOT USE SOLVENTS TO CLEAN THE OUTPUT GEAR! 3. Using a brush or other applicator, apply a thin coat of grease to the servo output gear. Use Aeroshell 17 or equivalent (Synthetic Diester, Low Temp; Must meet MIL-G-21164D). 4. Re-install the servos.   5. Move control surfaces through their range of motion."
