ENGINE OIL: SYNTHETIC OIL VS CONVENTIONAL OIL

Like conventional motor oil, synthetic oil goes through a refinement process to reduce impurities, but it also goes through advanced levels of hydrotreatment which transforms the oil at a molecular level for greater performance. Synthetic oils hold their viscosity longer, function more efficiently at low and high temperatures, and resist oxidation and deposit formations, reducing the oil change intervals. For modern, high-performance vehicles, synthetic is often recommended by the manufacturers. For those looking to get the extra protection in today’s harsh driving conditions, synthetic motor oil is the only choice.
