It is also used as a solvent for oils and fats. Unleaded gasoline is just the normal gasoline sold these days - Lead has not been used to enhance octane ratings since the 1970s in the USA or in other countries from the 80s or 90s, but the "unleaded" name stuck, so it's still often called unleaded gasoline rather than just gasoline. Gasoline, for example, has eight carbons, while light gases like propane have only three. Most of the gasoline that petroleum refineries produce is actually unfinished gasoline (or gasoline blendstocks). Gasoline, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. In the past, gasoline was added with compounds of organic lead to reduce the knocking in engines. In this article, you will learn exactly what gasoline is and where it … Gasoline actually must be produced from a thick, dark substance pumped from deep underground. ­ ­Gasoline is made from crude oil. Achetez neuf ou d'occasion Retrouvez How Is Gasoline Made and Sold? The original question was “How can we produce gasoline?” and that is the question that I will now answer.
