Synthetic oil is a type of lubricant made from chemically engineered compounds, designed to provide better performance than conventional mineral oils. It offers superior protection against engine wear, improved temperature stability, and enhanced fuel efficiency. Synthetic oils are often used in high-performance vehicles and extreme driving conditions. Unlike traditional oils derived from crude oil, synthetic oils can be tailored to meet specific requirements, making them suitable for various applications. They typically have a longer lifespan, which means less frequent oil changes, contributing to reduced waste and environmental impact. Popular brands include Mobil 1 and Castrol.
