Topic: Water Displacement

A correction is issued regarding the history of WD-40, confirming the name stands for "Water Displacement, 40th formula," which was originally used to protect Convair Atlas missiles. The discussion clarifies the difference between "sweet crude" and "sour crude" oil, noting that sour crude contains high levels of sulfur and requires more processing. European Commission President Ursula von der Leyen's recent comments on "dirty" Russian fossil fuels are attributed to this sulfur content.

A historical anecdote claims that WD-40 (Water Displacement, 40th formula) was originally developed to prevent water from freezing on the outer skin of the Atlas rocket during the early space program. The product was designed as a penetrant and water displacer rather than a primary lubricant, specifically to protect the thin-skinned fuel cells of the rocket.
