How does synthetic oil differ from regular oil in terms of performance and longevity? Synthetic oil differs from regular oil (conventional oil) in several key aspects. Unlike regular oil, which is derived from crude oil and contains impurities, synthetic oil is chemically engineered in a controlled environment to create a purer product with a more uniform molecular structure. This results in superior viscosity properties across a wider temperature range, providing smoother cold starts and better protection under extreme conditions. Synthetic oil also lasts longer between oil changes, reduces engine deposits and sludge buildup, improves fuel efficiency, and offers better oxidation resistance. These differences make synthetic oil the preferred choice for drivers looking to optimize their engine's performance and longevity.
