Choosing the right oil for your vehicle isn’t always as straightforward as it seems. Walk into any auto parts store or service center, and you’ll see options for synthetic oil, conventional oil, and even synthetic blends. But what’s the difference—and which one is the best choice for your car?
At L.A.W. Inc. Auto Repair in Nashville, we break down the pros and cons of each so you can make an informed decision.
What Is Conventional Oil?
Conventional oil is made from refined crude oil. It has been the standard for decades and works well in many older vehicles.
Pros:
-
Lower upfront cost compared to synthetic
-
Effective for basic engine protection
-
Suitable for vehicles with simpler engine designs
Cons:
-
Breaks down faster in extreme temperatures
-
Requires more frequent oil changes
-
Provides less protection for high-performance engines
What Is Synthetic Oil?
Synthetic oil is engineered in a lab to provide superior performance and protection. It’s designed to withstand extreme heat, cold, and stress inside modern engines.
Pros:
-
Lasts longer, extending the time between oil changes
-
Flows better in cold weather for easier starts
-
Provides better protection against engine wear and sludge buildup
-
Ideal for high-performance or turbocharged engines
Cons:
-
Higher upfront cost per oil change
-
Not always necessary for older or low-mileage vehicles
What About Synthetic Blends?
A synthetic blend is a mix of conventional and synthetic oils. It offers some of the benefits of synthetic oil at a lower cost, making it a popular middle-ground option.
Which Oil Should Nashville Drivers Choose?
-
Newer vehicles (especially those under warranty): Often require synthetic oil for maximum protection.
-
High-mileage cars: May benefit from synthetic blends or high-mileage synthetic oils.
-
Older vehicles: May run just fine on conventional oil, though switching to synthetic can extend their lifespan.
-
Extreme conditions: With Nashville’s hot summers and chilly winters, synthetic oil provides added peace of mind.
