Synthetic motor oils are blended in order for the building up of sludge under worst engine conditions to be prevented. Synthetic motor oils, as compared to conventional or even regular motor oils are injected as well as blended with artificial chemical compounds that are not present in natural crude oil. This would create uniform weight and size of molecules in oil.
Engine sludge can be produced by impure oils and fuels, acid, metals, dirt deposits and wear on the engine so chemicals that are added to synthetic motor oils are designed to collect these agents as a way to protect the engine. The crude oil, from where the synthetic oils are derived from made up of hydrogen and carbon atoms and other organic compounds. In creating synthetic oil, more organic compounds are added and these are manipulated to create the right proportions and size of molecules for the better performance and preservation of engine.
The purpose of motor oils is to minimize friction created due to the engine parts that move against each other that wear down the parts. This friction can also create additional heat that results to a waste of power. Conventional motor oil can help clean the engine, lubricate and reduce friction. Moreover, it can also slow down the rate of corrosion and carries the heat out from the engine to keep it cool.
On the other hand, synthetic motor oil is designed in such a way that it can help create better fuel efficiency for vehicles. It can reduce the friction even further than the conventional motor oil can since it has uniform molecule. Synthetic motor oil also has the ability to resist high temperatures, resist oxidation, keeps the engine cooler, and keeps the oxygen level out of oil which means that less sludge can be formed.
Synthetic oil is not recommended for all types, makes and models and vehicles. For instance, older model vehicles can perform better with the use of conventional oils for it is what they were designed to utilize. You can therefore consult the owner manual in order for you to find the oil that can help you use engine performance.
