The word "gasoline" doesn't come from the word "gas", as you might have expected.
It actually comes from the brand name "Cazeline", after English entrepreneur John Cassell. Who was one of the first to sell it commercially, successfully.
A competitor of Cassell, Samuel Boyd of Dublin, began selling motor spirit under the same name of Cazeline, Cassell sent a letter to Boyd requesting that he cease immediately, Boyd never responded and instead changed all of the C's on the containers to G's.
Thus creating the brand of "Gazeline", which varied in spelling over time.
This term for the fuel gained traction and eventually became the predominant term in North America and numerous other places around the world. Petroleum being the other most popular, which is named after one of the stages of its distillation.
This makes me think of how after the iPhone came out a bunch of cheaper phones were released with names like aPhone or I-Phone and such, just change it enough that it's legal and you can ride all the coat-tails you want.
