Synthetic vs. Conventional Engine Oil - Which is the Best for Your Car?

Synthetic vs. Conventional Engine Oil - Which is the Best for Your Car? | Silverstar Automotive Solutions

Choosing the right engine oil for your car can feel like navigating through a maze. With options like synthetic, conventional, and even blends, it's easy to get lost.

But don’t worry - we are here to explain the mystery and help you decide which oil is the best fit for your vehicle.

Understanding the Basics

Conventional oil
Refined from crude oil, it's the most affordable option. However, it breaks down faster under extreme temperatures and has a higher viscosity, meaning it flows less easily when cold.

Synthetic oil
Created in labs, it offers superior performance with more uniform molecules, leading to better viscosity control and extreme temperature protection. This means that it comes at a higher price tag.

Synthetic blend
A mix of conventional and synthetic oils, offering a balance between affordability and performance.

Factors to Consider

1. Your Car's Age and Mileage

Synthetics can be beneficial, especially for turbocharged engines or high-performance models. Their higher viscosity index ensures easier cold starts and better protection during intense driving.

Conventional oil might suffice, especially if you drive moderately and prioritize budget. If your car has high mileage, consider a high-mileage conventional oil designed for older engines.

2. Your driving habits and dynamic

Synthetics excel here, maintaining viscosity better throughout short trips, reducing wear and tear.

Both types fare well, but synthetic's thermal stability might offer an edge if you tow frequently or drive in extreme temperatures.

Conventional oil is suitable, as long as you follow recommended oil change intervals.

Did you know?
Used motor oil is a hazardous waste. Dispose of it responsibly at designated recycling facilities.

3. Climate

Synthetics resist thinning at high temperatures, providing better lubrication and engine protection. It also flows more easily when cold, ensuring proper lubrication when winter starts.

4. Cost

  • Conventional oil - Most affordable option, but more frequent oil changes might be needed.
  • Synthetic oil - More expensive upfront, but longer oil change intervals can offset the cost over time.
  • Synthetic blend - Offers a middle ground in terms of price and performance.

Looking for eco-friendly options?
Some synthetic and synthetic blend oils are formulated with bio-based ingredients and offer improved fuel efficiency.

So, Which Is Better?

There's no one-size-fits-all answer. Both conventional and synthetic oils have their strengths. Here's a quick decision tree:

  • Prioritize affordability and moderate driving: Conventional oil might be sufficient.
  • Value performance and drive in extreme conditions: Synthetic oil is likely the better choice.
  • Seek a balance between cost and performance: Consider a synthetic blend.
  • Always consult your owner's manual for the recommended oil type and viscosity grade.

Questions You Might Have

How often should I change my oil?

 Follow your car's manual recommendations, considering your driving habits. Synthetics often allow for longer intervals, but consult your mechanic for specific advice.

Can I switch from conventional to synthetic oil?

Yes, usually without any issues. Consult your mechanic if unsure.

Are synthetic blends as good as full synthetic oil?

They offer improved performance compared to conventional but might not match the full potential of synthetics under extreme conditions.
