Synthetic Oil Vs. Conventional

Conventional oil is laden with natural impurities and irregularities, impurities that reduce efficiency and place a limit on performance. Synthetic oil is pure, free from these natural limits that regular oil faces. They have a uniform molecular structure that impart properties that provide wear protection, extreme-temperature performance, and fuel efficiency that conventional lubricants just can’t touch.
