Oil is the lifeblood of your engine — it keeps everything running smoothly, reduces friction, and prevents costly wear and tear. But when it’s time for an oil change, you’re faced with a big decision: synthetic or regular (conventional) oil. At Route 133 Auto, we help drivers make smart maintenance choices every day. Let’s break down the difference between the two and find out which one is right for your car, truck, or SUV.
What’s the Difference Between Synthetic and Regular Oil?
Regular (Conventional) Oil is refined directly from crude oil. It provides basic engine protection and lubrication but contains impurities that can break down faster under heat and stress. Synthetic Oil, on the other hand, is chemically engineered to deliver uniform, high-performing molecules. It’s designed to withstand higher temperatures, flow better in cold conditions, and last longer between oil changes.In short: Synthetic oil is cleaner, more consistent, and better for your engine’s long-term health.
⚙️ 5 Reasons to Choose Synthetic Oil
- Superior Engine Protection
Synthetic oil resists breakdown and maintains viscosity, protecting your engine even during extreme heat or cold. - Improved Performance and Fuel Efficiency
Because synthetic oil flows more freely, your engine doesn’t work as hard — which can improve fuel economy and reduce emissions. - Better Cold-Weather Starts
On chilly Massachusetts mornings, synthetic oil circulates faster, ensuring your engine is protected the moment you turn the key. - Longer Oil Change Intervals
Synthetic oils last longer — typically 7,500 to 10,000 miles, compared to 3,000–5,000 for conventional oil (always check your manufacturer’s specs). - Cleaner Engine
Synthetic oils contain fewer impurities and include detergents that reduce sludge buildup,keeping your engine cleaner and extending its life.
When Regular Oil Might Still Work
For older vehicles or those driven infrequently, conventional oil can still be an acceptable (and more budget-friendly) choice. Some classic car owners even prefer conventional oil to maintain original engine characteristics.However, if your car faces stop-and-go traffic, harsh weather, or long commutes — synthetic oil offers better protection and peace of mind.
