3-in-One Oil is a general-purpose lubricating oil sold for household and do-it-yourself use. It was originally formulated in 1894 for use on bicycles, and remains a popular lubricant for their chains. Its name, given by inventor George W. Cole of New Jersey in 1894, reflects the product's triple ability to "clean, lubricate and protect".
The product changed ownership many times throughout the 20th century and was bought by its current owners, the WD-40 Company, in 1995. The current marketing slogan is "The Tool Kit In A Can," with the logo of the text "3 in" inside a large numeral "1".
An advertisement found in "The Church Standard" magazine (April 13, 1901, pg. 867) offers 3 in 1 Oil as a perfect polish for pianos. It claimed that the oil was "long lasting" and did not come off on the clothes.
