If you’ve ever taken your car in for an oil change in Scarborough, you’ve probably been asked: “Do you want synthetic or conventional oil?” It’s a simple question, but the answer depends on your vehicle, your driving habits, and your long-term goals.
At EuroMechanic – Redline Automotive, we’re often asked which type of oil is better. The truth is, both synthetic and conventional oils have their place — but choosing the right one can help extend the life of your engine and save you money in the long run.
What Is Conventional Oil?
Conventional oil is the traditional motor oil made from refined crude oil. It’s been used for decades and is still widely available and affordable.
Pros of Conventional Oil:
- Lower cost upfront
- Adequate for older vehicles and basic driving conditions
- Easy to find and widely used
Cons:
- Breaks down faster at high temperatures
- Requires more frequent changes (usually every 5,000 km)
- Doesn’t perform as well in extreme temperatures
If you drive an older car or mostly use your vehicle for short city commutes, conventional oil may still meet your needs — especially if you’re diligent with your maintenance schedule.
What Is Synthetic Oil?
Synthetic oil is chemically engineered to offer better performance and protection. It’s made from refined base oils with additives that enhance stability, reduce friction, and extend engine life.
Pros of Synthetic Oil:
- Better high- and low-temperature performance
- Longer oil change intervals (often up to 10,000–12,000 km)
- Reduces engine wear and sludge buildup
- Improves fuel efficiency in many cases
Cons:
- Higher cost per service
- May be unnecessary for low-demand driving styles or older engines
If you own a newer vehicle, drive long distances, or frequently encounter extreme temperatures, synthetic oil is almost always the better choice. Many modern engines are specifically designed for synthetic oil — and switching back to conventional isn’t recommended.
How Do You Know What’s Right for Your Vehicle?
Your owner’s manual is a great starting point. Manufacturers will usually list the recommended oil type and viscosity based on the engine design.
Beyond that, consider how and where you drive. Scarborough drivers deal with a mix of stop-and-go city traffic and longer commutes — which can place extra strain on your engine and accelerate oil breakdown. In these cases, a synthetic oil change service can offer better protection.
If you’re unsure, our Scarborough mechanics can inspect your engine, review your driving habits, and make a personalized recommendation.
Does Synthetic Oil Really Extend Engine Life?
Yes — in most cases. Synthetic oil’s resistance to breakdown helps prevent the formation of sludge, keeps moving parts better lubricated, and maintains stability even in extreme weather. That translates to less wear and tear, fewer surprises at the mechanic, and more peace of mind behind the wheel.
Long term, using synthetic oil can help reduce your risk of major repairs, particularly in turbocharged or high-performance engines.
Can You Switch Between Oil Types?
It’s a common question — and the answer is yes, in most cases. However, once you switch to synthetic, it’s usually recommended that you stick with it.
Mixing oils or switching frequently can dilute the benefits of synthetic oil. If you’re driving an older vehicle or one with high mileage, it’s also a good idea to check with a mechanic in Scarborough before switching types, just to make sure it’s the right fit for your engine’s condition.
The Cost Comparison: Is Synthetic Oil Worth It?
While synthetic oil does cost more per service, it also lasts longer — meaning fewer oil changes per year. More importantly, it helps prevent engine problems that could lead to major repair bills down the road.
Think of it as preventative care. You’re spending a bit more today to avoid bigger issues tomorrow.

Choosing between synthetic and conventional oil really isn’t that complicated — and for many drivers, the decision is already made based on your car’s make, model, and manufacturer recommendations.
