Synthetic oils have the same base of liquids as natural oils do. There are a few problems with them though, as the molecules colide in the sythentic oils it produces less heat because the molecules are in uniformity and are about the same mass. With this synthetic oil we can add things to the mix like friction modifiers, detergents, disperants and antioxidants which gives us a advantage over conventional oil. Another advantage of the synthetic oil is that it flows better than conventional oil does in the cold and it also does deteriate as fast as convetional oil does at extreme change of temperature which could damage your engine if you were using conventional oil. The syntethic oils in slicker than coventional oil whcih means better horse power and better gas mileage but it leaks more than conventional oil. Since the oil is slicker and contains none of the impurities of conventional oil it creates less polution. These oils are both found in the ground but after that they are completely different, the synthetic oils are refined and changed to fit the demands of modern day engines, they are broken down into their basic molecules which will remove the impurities and than they can enhance the oil.
With the new oil we can protect and prolong our cars quality and keep it running longer. The new oil will also create less pollution because it lasts longer than normal oil and doesnt produce as much heat. We can protect our engines with the oil because they modify it to create a thicker wall between parts in the engine which helps them to not touch and cause damage to the engine and other parts of the vehicle. Another thing the oil is good with is temperature resistance, it will run better and help us more than conventional oil does if were in a cold climate.
