Yes, synthetic oil generally offers superior performance and protection compared to conventional oil. However, the "better" aspect needs further clarification, as it depends on various factors.
Advantages of Synthetic Oil
- Longer Life: Synthetic oil lasts longer than conventional oil, often requiring less frequent changes. This translates to cost savings over time, despite the higher initial purchase price. [Source: Quora - Is synthetic oil better for your engine than conventional oil?]
- Improved Protection: Synthetic oil provides better protection against wear and tear, especially under high temperatures and demanding driving conditions. [Source: Mobil - Synthetic oil vs. conventional oil]
- Better Performance: It enhances engine performance, leading to potentially better fuel economy. [Source: Quora - Should you switch to synthetic oil?]
- Reduced Sludge Buildup: Synthetic oil reduces sludge buildup, a common problem with conventional oil, keeping the engine cleaner. [Source: Reddit - I was told Synthetic Oil is a waste of money]
- Superior Flow: It flows more smoothly at lower temperatures, allowing for quicker lubrication upon engine startup, particularly beneficial in cold climates. [Source: McCluskey Chevrolet - Benefits to Sticking with Conventional Motor Oil; BobIsTheOilGuy - Is synthetic oil really improve MPG?]
Considerations for Older Engines
While generally superior, synthetic oil's smoother flow might pose a slight disadvantage in older engines. The improved flow could potentially exacerbate existing seal leaks or cause issues with worn components.

Is the Price Difference Justified?
The higher initial cost of synthetic oil is often offset by its longer lifespan and better engine protection. Many sources suggest the long-term cost difference is not substantial. [Source: Quora - Is synthetic oil better for your engine than conventional oil?]
Conclusion
Synthetic oil provides superior lubrication, protection, and longevity compared to conventional oil, often resulting in cost savings in the long run. The initial higher price is generally justified by its performance advantages, although older engines might present a nuanced consideration.
