You have the option of choosing from conventional or synthetic oil for your vehicle. Synthetic oil is made up of artificial compounds. People prefer synthetic oil over conventional oil because it is often marketed as being the superior type of oil. There is evidence to back up the claim that synthetic oil is superior to conventional oil. The American Automobile Association conducted tests on synthetic oil and determined that the synthetic oil was 47 percent more efficient than the conventional oil.
Synthetic oil is also designed to last longer than conventional oil. You will likely be able to go longer without an oil change if you use synthetic oil. Most vehicles need an oil change after they have been driven for 5,000 to 7,000 miles. However, if synthetic oil is used, then you may be able to go up to 15,000 miles without one.
