No comments yet on the fact that the oil in the engines <span style="font-style: italic">does not get changed</span> ? Ever. They do refer to topping it off and that alone keeps the oil "fresh" enough.
be nice if they'd bring down the price on Krytox grease, $600 a cartridge.
If you have lived your life so far without the need for Krytox series lubricants, then you do not need them. The Krytox series of lubricants have very narrow and specific applications they are made for, hence the cost. The actual market for and quantity needed for them is small comparatively speaking.
