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.
FAQs & Answers
- Is synthetic oil worth the higher cost? Yes, synthetic oil offers enhanced performance and longevity, but the cost may be a concern for some drivers.
- Can synthetic oil damage older engines? Synthetic oil may expose existing leaks in older engines that are not designed for it, but it won't inherently damage them.
- How often should I change synthetic oil? Typically, synthetic oil can last longer than conventional oil, so changing it every 7,500 to 10,000 miles is common, but always check your owner's manual.
