How and when to lubricate a springer???

So I have done the search and watched the videos, and this is what I understand about lubricating the power plant of modern springers like the TX200 and R9/HW95.

1. Wipe off all the old grease including from the inside of the compression tube. Do not use solvents, especially inside the compression tube. You want to leave a thin film of lubricant on all metal parts to prevent galling and rusting.

2. Using a high quality airgun grease like the type sold by Vortek, lubricate the spring and guides. There can be enough grease in these locations to be easily visible, but no need to pack the spring and guides with grease.

3. Now the tricky part. Lubricate the OD of piston and seal with the same grease, but this time leaving only a very thin film. There should be no visible accumulation of grease on the OD of piston and seal, just that very thin film. There should be no grease at all on the front of the seal.

4. Do not apply any grease to the inside of the compression tube. Enough will be transferred from the OD of the piston to let parts slide freely and prevent galling.

5. Lubricate the running surfaces of cocking slot and cocking shoe with grease, preferably moly.

6. Do not try to add oil or other lubricant through the transfer port. It will only cause dieseling. Proper lubrication requires disassembly.

Does this sound right so far? I hope so, because that is what I have been doing.

Now the question. How do you know when to relube? I read somewhere that you should wait until the seal starts squeaking. Is this still the recommendation? About how long do you wait before relubing the internals of your springer?

Both HW and Air Arms caution against putting any lubricant in the compression chamber. HW does say to lubricate the spring through the cocking slot periodically. Beyond that, factory service is recommended. Having experienced broken springs in both an R8 and an R9 running factory lubes, with dieseling suspected as the cause, I am now in the camp that believes it is best to replace the usually excessive factory lubrication with carefully applied synthetic grease.

Surely there is somebody out there who has what they believe is a proven system for teardown and periodic relubrication of thier springers. So far what I described above seems to be working. Have I missed anything? And once lubricated in this manner, how long or how many shots before the gun will need to be relubricated? Is this expected to be a yearly maintenance item, or will it only needed to be done every few years or after putting several thousand pellets through the gun?

Any helpful hints you can provide would be appreciated.
