Synthetic oil is chemically engineered to provide superior lubrication and protection for the engine. It is created through a complex process that involves refining and modifying petroleum-based or synthesised compounds. On the other hand, conventional oil is derived directly from crude oil and undergoes basic refining processes. One key distinction between synthetic and conventional oil lies in their performance under extreme conditions. Synthetic oil has a more uniform molecular structure, which allows it to flow better at low temperatures, providing easier starts and reduced wear during cold weather. It also exhibits better stability at high temperatures, resisting breakdown and maintaining consistent lubrication. In contrast, conventional oil may struggle to flow smoothly in colder temperatures and can break down more quickly when exposed to high temperatures, leading to decreased performance and potential engine damage.
