This is a good question. The key is to ask what is the equivalent of friction, and what removes it. Friction : lubrication :: X : Y.
I think it's bitrot/entropy and the solution is organization. So a well-organized computer. Which is a property of usage rather than the device.
Wouldn’t organization at the bit level be defragmentation? Except that is now something operating systems can do on their own, whereas machines can’t oil themselves
Defragmentation is very specific to magnetic disks and other serial physical media. The actual low-level equivalent is deleting bits, which generates heat and obeys the 2nd law (Landauer principle). It's not particularly important in the "oiling" maintenance sense though.
another interesting analogy direction is leaks... a well-oiled machine has no leaks... a closed circulation lubrication system with minimal oil leaks, proper gaskets/seals etc. The equivalent in computers would be no memory leaks, and equivalents all the way up.
