When it’s time for an oil change, one of the biggest questions vehicle owners face is whether to choose synthetic or conventional motor oil. Both types of oil play a vital role in keeping your engine lubricated and running smoothly, but they differ in formulation, performance, and cost. At Harris Automotive, we often get asked which option is best, and the answer depends on your vehicle, driving habits, and budget.
Here’s a breakdown of the pros and cons of synthetic vs. conventional motor oil to help you make an informed decision.
What Is Conventional Motor Oil?
Conventional oil is derived directly from crude oil and has been used for decades in internal combustion engines. It provides adequate lubrication and protection for most basic driving conditions.
Pros of Conventional Oil:
- Lower Cost: Conventional oil is generally more affordable, making it a good choice for drivers on a budget or with older vehicles.
- Widely Available: It’s the standard oil offered at most service centers and is compatible with many engine types.
- Good for Older Engines: Some older vehicles perform better with conventional oil, especially if they’ve never used synthetic before.
Cons of Conventional Oil:
- More Frequent Oil Changes: Conventional oil breaks down faster and typically needs to be changed every 3,000 to 5,000 miles.
- Less Performance in Extreme Temperatures: It doesn’t flow as well in cold weather and may not offer the same protection under high heat.
- More Engine Deposits: Conventional oil is more likely to leave behind sludge and carbon buildup over time.
What Is Synthetic Motor Oil?
Synthetic oil is chemically engineered for optimal performance, offering better protection, stability, and longevity. It’s designed to flow smoothly at extreme temperatures and resist breakdown over time.
Pros of Synthetic Oil:
- Longer Lasting: Synthetic oil can often go 7,500 to 10,000 miles between changes, depending on your vehicle and driving conditions.
- Better Performance in Extreme Temps: It flows better in cold starts and maintains stability in high heat – ideal for Ohio’s varying climate.
- Cleaner Engine Operation: Fewer impurities and better chemical stability mean reduced engine deposits and sludge.
- Improved Fuel Efficiency: The smoother flow and reduced friction can slightly boost your MPG.
- Superior Engine Protection: It reduces engine wear and tear, especially during heavy-duty use or high-performance driving.
Cons of Synthetic Oil:
- Higher Cost: Synthetic oil is more expensive than conventional oil, though the longer intervals between changes can offset the price.
- Not Always Necessary: For older, low-mileage vehicles with simple engine designs, synthetic oil may not offer much added benefit.
- May Not Be Compatible with Some Engines: Always check your vehicle’s manual. Older engines or those with specific seals may not be ideal for synthetic blends.
Which Oil Is Best for Your Vehicle?
Choosing between synthetic and conventional oil comes down to your car’s requirements, your driving style, and your maintenance goals.
Synthetic Oil Is Ideal For:
- Newer vehicles with high-performance or turbocharged engines
- Drivers who regularly tow or haul heavy loads
- Those who take frequent short trips or drive in extreme heat or cold
- Anyone looking for extended engine protection and fewer oil changes
Conventional Oil Is Best For:
- Older vehicles with high mileage that have always used conventional oil
- Drivers on a tight budget
- Cars that are driven infrequently or only for short distances
