Difference
-
Both synthetic and regular oil are derivatives of crude oil. The difference is in the manufacturing and refining. Synthetic oils are more refined and have more additives that aid in higher temperature resistance, longer lifespan, lower viscosity and fewer contaminants. Naturally, synthetic oils cost more.
Key Concepts
-
Viscosity is an important term. This refers to a liquid's resistance to movement. Maple syrup would have a higher viscosity than water. In car engines low viscosity means less resistance, less wear, lower temperature and increased horsepower. Both regular and synthetic oils come in varying viscosities.

Verdict
-
The most important thing is to use the oil type mentioned in the car's manual and to change it regularly. An engine that has had its oil maintained will last much longer than one that hasn't. The choice for synthetic is personal. If you are a person who is heavy on the gas and forgetful when it comes to maintenance, then synthetic might be your choice.
