Is there a downside to synthetic oil?
As the owner of Kevin's Autos, I often encounter questions about the benefits and drawbacks of synthetic oil. While synthetic oil is widely praised for its superior performance and longevity, it's essential to consider some potential downsides before making the switch. In this article, we'll explore the pros and cons of synthetic oil to help you make an informed decision for your vehicle.
Understanding Synthetic Oil
Synthetic oil is a man-made lubricant designed to provide better performance than conventional oil. It is engineered from chemical compounds, which allows for a more consistent and stable product. However, despite its advantages, there are some downsides to consider.
Potential Downsides of Synthetic Oil
- Higher Cost: One of the most significant drawbacks of synthetic oil is its price. Synthetic oils can be two to three times more expensive than conventional oils, which may deter some vehicle owners from making the switch.
- Compatibility Issues: Not all engines are designed to run on synthetic oil. Some older vehicles may not be compatible with synthetic oils, leading to potential engine issues. Always check your owner's manual or consult with a professional before switching.
- Oil Consumption: Some engines may consume synthetic oil more quickly than conventional oil. This can lead to more frequent top-offs and increased maintenance costs over time.
- Misleading Marketing: The marketing around synthetic oils can sometimes be misleading. While they offer excellent performance, not all synthetic oils are created equal. It's crucial to choose a reputable brand and product that meets your vehicle's specifications.
Conclusion
While synthetic oil offers numerous benefits, including better engine protection and longer intervals between oil changes, it's essential to weigh these advantages against the potential downsides. By understanding both sides, you can make a more informed decision that best suits your vehicle's needs and your budget.

Frequently Asked Questions
Can switching to synthetic oil cause problems?
Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine. Of course, this depends on the current engine condition and the quality of the conventional oil being used.
Will synthetic oil hurt older engines?
The bottom line is that there are no hard and fast rules as to whether using synthetic oil in your older car will be harmful or helpful. You'll need to speak to a trustworthy, knowledgeable mechanic about your specific vehicle to determine whether synthetic oil could be the right choice for you.
When should you not use synthetic oil?
Older Vehicles: Some older engines, particularly those designed before synthetic oils became popular, may not be compatible with synthetic oil. These engines can have seals and gaskets that were not designed to handle the additives in synthetic oils, which could lead to leaks.
What happens if I use synthetic oil instead of regular?
Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine. Of course, this depends on the current engine condition and the quality of the conventional oil being used.
What are the cons of synthetic oil?
Probably the most glaring downside of synthetic oil is the cost. The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions.
Is synthetic oil bad for high mileage engines?
Full synthetic oil is good for high mileage cars because it results in the least engine wear. Mineral oils result in the most wear in an engine. The difference between semi-synthetic and full synthetic is relatively small... but it's still there. A full synthetic will outperform a semi-synthetic.
What is the disadvantage of fully synthetic engine oil?
The price of synthetic oil is around two to four times the price of conventional oil. Synthetics may be more prone to additives precipitation during cold storage conditions. This stratifies certain additives which can potentially lead to their complete separation from the oil.
Is it better to change oil, synthetic or regular?
Synthetic oils provide significantly better lubrication than conventional oils. So, it would be a good idea to switch to synthetic oil even for a high mileage vehicle if you intent to keep it for a long time.
Why can't you go back to regular oil after synthetic?
Here is the problem: Synthetic oil has smaller molecules and higher densities. If you switch from synthetic to coventional...the gaskets and seals that had no cracks with the other larger molecules could start to deteriorate with expansion and heat with synthetic oil now in place.
Is it worth switching to fully synthetic oil?
The single-phrase answer is: “Yes, but it will cost more”. Many of the advantages of synthetic oil are in helping your engine last longer. If you plan to keep the car for a long time, possibly passing it down through the family, synthetic oil would be a good first step in that goal.
