What is the difference between regular oil and conventional oil? Regular oil, derived from crude oil, contains impurities and undergoes minimal processing. In contrast, synthetic oil is chemically engineered in a controlled environment, resulting in a purer product with a more uniform molecular structure. Synthetic oil offers better viscosity properties across a wider temperature range, providing smoother cold starts and superior protection under extreme conditions. It lasts longer between oil changes, reduces engine deposits and sludge buildup, improves fuel efficiency, and offers better oxidation resistance. Overall, synthetic oil offers superior performance and longevity compared to regular oil, making it the preferred choice for many modern engines.
