At least if some gets by the air dryer it is formulated to be used in air tools so it won't have anything that may potentially eat at o-rings, valves, sensors, etc and will actually lubricate them a little.

That or a bit of 3-in-1 oil perhaps if you can't find air-tool oil handy? - Very similar.

I think the 'wd-40' thing is from an old cummins bulletin about the compressor head getting sooty and sticking if I am not mistaken. i thought it odd back then to recommend that stuff too, as it is a terrible lubricant, and prone to hardening seals and deteriorating plastic air lines. I had completely forgotten about that, thanks for bringing it up again.
