Synthetic vs Conventional Oil

All types of oil come from the ground but what happens during the refinement process changes how well they perform in an engine. Synthetic and conventional oils will both lubricate the engine but the former will do so better than the latter. Modern cars are created to use synthetic oil to the fullest extent, making conventional oil seem outdated.

Conventional oil is simply refined and put on the shelf. Synthetic oil is refined, distilled, and purified before heading to dealerships. The longer process results in less impurities and an oil engineered to meet the requirements of modern engines.

Due to the lower amount of impurities, synthetic oil will keep your engine cleaner and help prevent the buildup of sludge. It will also protect the parts better than conventional oil by acting as a barrier between moving parts.

Unlike conventional oil, synthetic oil's viscosity doesn't change as much during temperature extremes like those during summer and winter.

Finally, synthetic oil better protects turbocharger parts, effectively ensuring the engine runs at peak performance for a longer period of time.

Which Is Better?

While some older cars may require conventional oil, it wouldn't be a bad idea to ask a technician about using synthetic oil instead.
