Disadvantages of fully synthetic oil include higher cost and potential for compatibility issues with older engines not designed for it. Synthetic oil's superior properties mean it can expose existing leaks by not swelling seals like conventional oil. It may also degrade faster in specific high-stress conditions. However, its enhanced performance and longevity often outweigh these downsides.
