My experiences with these lubricants are similar to Mr. Wallace. I agree
that WD-40 is rather limited, there are better penetrating oils. I do know
that the Navy squadron I was in a little over 20 years ago discontinued
using WD-40 as a rust preventative. Good corrosion control practice is to
coat the holes and fasteners when re-installing any removed airframe
component. The WD-40 just wasn't holding up to the salt air environment.

WD-40 is not a light oil, but I'm not sure what it is. It was
originally developed to spray on things to prevent them from rusting.
I've been told NOT to use it for such things as lubricating bushings
in small electric motors. 3-in-1 is the thing to use there; it's
apparently equivalent to about SAE-5.
WD-40 is really not that great as a penetrating oil. For a
penetrating oil, I've had better luck with "Release-All".
Graphite's good where you can't handle grit sticking to it; it's often
recommended for such things as starter motor pinions and door locks.
The idea is that you can't live with it thickening over time.
Vaseline seems to be good over battery posts to prevent "green crud
build-up." Sort of as a sealer against the elements; it will stay put.
White grease just seems to be light-duty grease. I use it intuitively
where I think it will work well, with no real knowledge of why. It's
good for rear brake cylinders that slide on backing plates, or for
speedometer cables.
If anyone knows that I'm doing something I'll regret later, your
comments are welcome!
Hope this helps,
Jim Wallace

Can anyone tell me the pros & cons for different types of lubricants?
Some examples : WD-40, 3-in-one oil, vaseline, white grease and
graphite. Would wd-40 be a light oil? Thanks in advance, Brian.
