What is the disadvantage of fully synthetic engine oil?
Fully synthetic engine oil has become a popular choice among car owners due to its superior performance and longevity. However, like any product, it is not without its drawbacks. In this article, we’ll explore the primary disadvantage of fully synthetic engine oil and help you make an informed decision for your vehicle.
Higher Cost Compared to Conventional Oils
The most significant disadvantage of fully synthetic engine oil is its cost. Fully synthetic oils are more expensive than conventional or even semi-synthetic oils. This is because they are engineered with a more refined base oil and advanced additives, which enhance their performance but also increase production costs. For car owners on a tight budget, this higher price point can be a deterrent.
Potential for Overkill in Older or Low-Mileage Vehicles
While fully synthetic oil offers excellent protection and performance, it may not always be necessary for older vehicles or those with low mileage. In such cases, the benefits of synthetic oil might not justify the additional expense. Conventional or semi-synthetic oils can often provide adequate protection for these types of vehicles, making fully synthetic oil an unnecessary luxury.
Compatibility Issues with Older Engines
Some older engines, particularly those designed before synthetic oils became widely available, may not be compatible with fully synthetic oil. These engines might have seals and gaskets that are not designed to handle the properties of synthetic oil, potentially leading to leaks or other issues. Always consult your vehicle’s manufacturer guidelines before switching to synthetic oil.
Environmental Concerns
Although synthetic oils last longer and reduce the frequency of oil changes, their production process can have a higher environmental impact compared to conventional oils. The refining and chemical processes involved in creating synthetic oil require more energy and resources, which can contribute to a larger carbon footprint.
Conclusion
While fully synthetic engine oil offers numerous advantages, such as superior performance, better engine protection, and longer intervals between oil changes, it is essential to weigh these benefits against its disadvantages. The higher cost, potential compatibility issues with older engines, and environmental concerns are factors to consider when deciding whether synthetic oil is the right choice for your vehicle.

Frequently Asked Questions
Can I use full synthetic oil on a high mileage car?
USING HIGH-MILEAGE SYNTHETIC OIL IN HIGH-MILEAGE ENGINES
High Mileage Synthetic Oils are specially designed for high-mileage vehicles that require synthetic oils with extra seal conditioner providing more protection to worn seals, which can mitigate leaks in high-mileage engines.
Can I go back to regular oil after using synthetic?
Yes, it's perfectly safe to switch to regular conventional oil after using synthetic oil.
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.
Is it bad to switch from regular oil to full synthetic?
Answer. 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.
Is it better to use fully synthetic engine oil?
Automotive experts recommend synthetic oil because of its longer lubrication life and its superior thermal stability over regular oil. Contrary to what is commonly believed, synthetic oil can actually be better for your car and for the environment.
Is full synthetic oil bad for your engine?
No, synthetic oils will not damage your car engine. In the past decade manufacturers have changed from petroleum oil to synthetic oils which provide less friction, better miles per gallon, and more advantages. Check your owner's manual for the requirements for your vehicle.
Will synthetic oil damage a high mileage engine?
USING HIGH-MILEAGE SYNTHETIC OIL IN HIGH-MILEAGE ENGINES
Those who decide to switch to high-mileage synthetic oil may face leakage problems due to the potential incompatibility of the synthetic used in certain oils with the engine's seal types.
Is synthetic oil ok for older engines?
Risks of Using Synthetic Oil in Older Cars
This is because many synthetic oils contain esters, which are organic compounds mixed with alcohol. This particular combination can be extremely rough on seals within the engine, which can cause the seals to wear down and begin to leak or burn oil.
Why can't you go back to regular oil after synthetic?
Myth: Once you switch to synthetic oil, you can never switch back. This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.
What is the major disadvantage of synthetic oils?
Disadvantages of synthetic oil
Multi-grade motor oils using synthetics may exhibit slightly less fuel economy at highway speeds compared to mineral oil. The oil could leak out of old engines with loose seals and gaskets. This is due to lower pour pont and flowing characteristics even at low temperatures.
