Long-Term Value: Is Synthetic Oil Worth the Extra Cost?
Through a process of distillation and purification, impurities are removed, but the molecular structure of the remaining hydrocarbons remains irregular. Choosing the right lubricant for your engine is one of the most important decisions for vehicle longevity and performance.
Manufacturers start with base chemicals and build uniform molecules designed for specific performance criteria, resulting a product with a consistent molecular structure that is far more resistant to thermal breakdown. These molecules vary in size and shape, which can lead to friction and breakdown at high temperatures.
Synthetic Oil Long Term Value: Sludge Resistance and Extended Drain Intervals
This translates to extended drain intervals, with many manufacturers recommending changes every 10,000 to 15,000 miles for synthetics, compared to 3,000 to 5,000 miles for conventional oil. Protection is another key area where synthetics excel.
