WD-40 literally stands for Water Displacement, 40th attempt.
That's the name straight out of the lab book used by the chemist who developed WD-40 back in 1953.
The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion -- a task which is done by displacing water.
Norm's persistence paid off when he perfected the formula on his 40th try.
WD-40 stands for "Water Displacement, 40th attempt".

I don't have the stuff here, and I'm no chemist to know what I see, but I do see that lubricant oils come from petroleum whenever possible (as does kerosene and gas).
If petroleum is not available, it can be sythesized to acetylene from limestone and coal.
I bet THAT'S helpful.
