👉 The Detroit fluid, also known as the Detroit Petroleum Fluid, is a thick, black, and highly viscous oil that was historically used as an additive in gasoline during the mid-20th century. It was primarily derived from petroleum and mixed with gasoline to improve its performance, particularly in cold weather, by reducing engine knocking and improving fuel efficiency. The fluid's unique properties made it ideal for enhancing the combustion process, though its use declined due to environmental concerns and the development of more efficient engine technologies. Today, it is largely obsolete but remains a subject of interest in discussions about alternative fuels and historical automotive engineering.
