Is synthetic oil really worth it? Before you spend extra at your next oil change, here’s what you need to know about how it works, why it matters, and when it pays off.

Key Takeaways:

  • Many modern engines require or recommend full synthetic motor oils due to their tighter tolerances and performance needs.
  • Synthetic oil can be engineered for better engine protection, especially in extreme temperatures, frequent short trips, stop-and-go traffic, and towing conditions.
  • Many synthetic oil options offer better cold-start flow, improved high-temperature performance, and reduced engine wear.
  • Firestone Complete Auto Care offers oil recommendations and synthetic oil changes from certified technicians you can trust to help keep your car running smoothly.

What Is Synthetic Oil?

Synthetic oil isn’t just “regular oil with extra ingredients.” It’s typically a motor oil that’s carefully engineered or selected at the molecular level to deliver more consistent performance than conventional oil. Most synthetic base oils used to make synthetic lubricants are highly refined, high-viscosity-index base oils derived from crude oil or natural gas.  Some synthetic base oils are derived from esters or plant oils. 

Why does that matter? Because selecting uniform molecules to behave more predictably inside your engine matters. Synthetic oil can flow faster during cold starts, resist thinning and breakdown at high temperatures, and maintain its protective properties longer under stress. That consistency helps reduce friction, limit deposits, and protect critical engine components—especially in today’s modern engines, which are built with tighter tolerances and higher performance expectations.

In short, when comparing synthetic vs. conventional oil, synthetic options are designed to work smarter across a wider range of conditions. That’s why many vehicle manufacturers now recommend or require it.

Benefits of Synthetic Engine Oil

So, is synthetic oil worth the extra cost? For many drivers, the answer is yes, especially if you fit one of these categories:

  • You drive frequent short trips, which don’t always allow oil to fully warm up
  • You deal with stop-and-go traffic or run lots of local errands
  • You live in extremely cold or very hot climates
  • You tow trailers, haul gear, or carry heavy loads

In these cases, the benefits of synthetic engine oil can include:

  • Improved flow during cold starts for faster lubrication
  • Better protection at extreme temperatures and under heavy loads
  • Reduced buildup and sludge in engine passages

Common Questions About Synthetic Oil

Is synthetic oil better than conventional?

Yes, synthetic motor oil is typically better in terms of performance, stability, and protection. It’s especially helpful in engines with high-performance requirements or for drivers who live in extreme conditions.

Can I switch from conventional to synthetic oil?

With very few exceptions, yes.  Some older rotary engines recommend against the use of synthetic engine oils. You should always consult your owner’s manual and a professional technician at your local Firestone Complete Auto Care to ensure your vehicle receives the correct engine oil viscosity and meets the vehicle manufacturer’s performance specifications.

How much does a full synthetic oil change cost?

Specific pricing varies by vehicle and oil type; however, you can find current deals and coupons on our Offers page

Is full synthetic necessary for my car?

Check your owner’s manual or ask your technician at your next service appointment. The service information or owner’s manual will post the recommended engine oil viscosity and performance specification for the engine oil. In many newer vehicles, only synthetic oils can meet these specifications.
