I believe Amsoil was the first automotive synthetic oil. Synthetics were first developed for turbine engine use to withstand the high temperatures and bearing speeds.
.
I believe it was the German scientist in World War II that developed the synthetic oil because Germany did not have oil Reserves to take care of their needs. Amsoil I believe used the German formula for their oil. I could be wrong but I don't think so and this is my subconscious thoughts coming out on this but I must admit I do value my own opinion.
