The Origins of Synthetic Oil vs Conventional Oil
 Both types of oil start out as the same unrefined crude oil. From this point on, each takes a separate path to becoming the lubricant that is used in automobile engines. Conventional oil is refined from the original crude using traditional methods, while synthetic oil is enhanced and altered on a molecular level with the use of chemical compounds in order to specifically make it suitable and beneficial for use as motor oil.
What Sets Synthetic Oil Apart
As a chemically engineered product, synthetic oil does a lot of good for your engine. One pro that's definitely worth mentioning is the fact that it has a longer lifespan than the conventional version. Synthetic oil is able to travel anywhere between 6,000 and 7,500 miles before needing to be changed. This is a significantly longer lifecycle than the 3,000 to 5,000 miles offered by conventional oil.
This inherent longevity on the part of synthetic oil brings us to its next benefit. Oil breaks down as it ages. When this happens, it progressively collects any dirt and debris that happen to be lying around throughout the engine. This goes on and on until a harmful sludge has formed that effectively muddles up the works and can result in quite a lot of damage. Because synthetic oil lasts longer, this destructive development is delayed and it's able to keep the inside of the engine cleaner for a longer period of time.
Its enhanced nature also enables synthetic oil to handle adverse temperatures more effectively. This durability makes it more reliable whether it's way below freezing or downright scorching outside.
