What is synthetic motor oil?

Synthetic motor oils are made of artificial materials. They can be a good choice for high output, turbocharged or supercharged engines, vehicles that are used for towing (especially during hot weather) or vehicles that are operated in extremely cold or hot climates. Synthetic motor oils, though several times more expensive than mineral-based motor oils, can improve fuel economy and provide longer intervals between changes. They also provide instant lubrication on start-up.
