Full synthetic oil is made differently from conventional motor oil, and vehicles that use it require fewer oil changes than those that use conventional oil. Drivers who put synthetic oil in their cars also notice less wear and tear on their vehicles.
Workers create conventional motor oil by refining natural crude oil. When workers create synthetic oil, they start with conventional oil as a base, but instead of using it to create the entirety of the oil, they add chemicals to alter the lubricant. Some synthetic oils use other raw-material lubricants.
Synthetic oil is thinner than conventional motor oil and lasts longer, creating an economical benefit to the customer. Synthetic oil is more expensive than conventional motor oil, so those who use it pay more for an oil change although they don't have to change it as often. Most vehicles that use synthetic oil need an oil change every 7,500 miles, whereas vehicles with conventional oil need an oil change every 3,000 miles.
It's a good idea to check the owner's manual of the vehicle to determine whether using synthetic oil is a possibility or even a requirement. Many vehicles accept both synthetic and conventional oil, but some vehicles require the use of only synthetic oil.
