You live in Saskatoon where the current temperature is -41o C. What happens when you suddenly have to go to hospital and your car engine oil is thick like jelly making it hard ? for the car to start correctly? What will be your first priority: changing your petroleum-based motor oil to synthetic oil or deciding not to go to the hospital even though you needed it at any cost? Let's see below why I mentioned synthetic oil as one of your choices. Synthetic Oil: Introduction and PurposeMany years ago, engineers realized that at elevated temperatures petroleum-based oils deteriorate and lose their lubricating capabilities. Over time, even petroleum-based oils begin to oxidize and create sludge, leaving harmful residues inside engines. This problem led Dr. Hermann Zorn (German) to develop synthetic oil for high-temperature use in jet aircraft engines. To overcome the degradation problem of petroleum-based oils, synthetic oil is formulated in a laboratory and does not contain naturally occurring chemicals that degrade at high temperatures. Additionally, synthetic oil is produced without many of the chemical compositions that contribute to oil oxidation and sludge buildup. Synthetic oil tolerates temperatures at which petroleum-based oils would burn. Synthetic oil is not distilled from crude oil. It is produced through a chemical process known as the Fischer-Tropsch process. It goes through many chemical reactions that use methane, carbon monoxide and carbon dioxide as raw materials. Synthetic oil not only works better in hot weather, but also offers various benefits in extreme cold conditions. Petroleum-based motor oil becomes thick at low temperatures, consequently requiring the starter motor and battery to work harder... middle of paper... are known as inorganic chemicals while people who deal with The use of synthetic oil are known as physical chemists and sometimes aerospace researchers/engineers. The Future of Synthetic Oil: Synthetic oil is primarily used in transportation engines such as aircraft jet engines, automobile engines, and military vehicles. As consumer, government and industry concerns shift toward greater efficiency and reduced emissions, especially in the United States, Europe and Japan, synthetic oil is making its way to meet all demands. The reasons for its use in transport engines are mentioned above. Work cited: "Synthetic engine oils". Car ratings. 09 January 2014 ."Synthetic oil." Wikipedia. 01 September 2014.
