Amsoil - Synthetic Vs Conventional #1

What Is Conventional Oil?

Conventional motor oil is a petroleum-based lubricant made from crude oil pumped out of the ground. Most motor oils are derived from heavy or semi-sweet crude, depending on the oil company and refinery that it is coming from. During the refining process, chemical additives are added to the motor oil to improve performance and add extra wear protection. 


Once fully blended, the oil is further refined to the various viscosities that are needed and bottled. Motor oils are tested extensively and must meet the various specifications set out by the American Petroleum Institute and the engine manufacturers themselves. However, as it is a natural product, the molecular structure of the engine oil will vary, which means that even high-end conventional oil products will have natural imperfections and additional mineral additives that are unable to be refined. 

What Is Synthetic Oil?

Synthetic motor oil, on the other hand, is a manufactured product that takes the best qualities of traditional oil and amps up the overall performance and wear protection through a synthetic process. Synthetic motor oil uses distilled crude oil as a base and chemically alters the original base product to be more consistent by rebuilding the very molecular structure of the oil through a process called hydrocracking and organic synthesis. Once completed, the new product undergoes a purification process before additives are added to enhance its protective qualities and performance. 

 

These added manufacturing steps ensure that the new product is better performing and more protective from the molecular level up. Whether you have a high-performance marine engine or a diesel truck, synthetic oil is a better overall product that will extend the life of your machine and eliminate lost horsepower from wear and tear. 

Advantages Of Synthetic Oil VS Conventional Oil

There are many advantages that synthetic oil has over conventional oil, especially the award-winning AMSOIL motor options. These advantages include: 

Superior performance 

Whether you are driving a high-end supercar or a stock car, synthetic motor oil is proven to perform better due to its superior mechanical and chemical properties in extreme cold and heat.

Enhanced Protection 

Synthetic oil better protects engines due to its thin film that can lube up even the smallest parts. Plus, with the additives that are added to better protect your engine from wear, heat and friction, your engine will be well-protected for years to come.

Overall Use 

Synthetic oil burns roughly 30% slower than conventional motor oil in extreme conditions and provides clients with a longer-lasting lubricant, even for long-haul voyages. In fact, synthetic oil will normally double the mileage that you can expect and will require fewer regular top-ups.

Frequently Asked Questions

No Dumb Questions, Just Dry Dipsticks

  • How much more mileage will I get out of synthetic oil?

    In general, you should expect to roughly double the mileage that you would normally get from conventional oil with synthetic oil. Most engines will require an oil change with synthetic oil every 7,500 to 15,000 miles or 12-18 months. However, you should always check with your vehicle's owner’s manual, or check in with your AMSOIL Independent Dealer in Toledo, OH. 

  • Is synthetic oil more expensive than conventional oil?

    Yes, synthetic oil usually is more expensive than conventional motor oil. However, with that higher price, you get a better-performing motor oil that will also extend the mileage of your last oil change. For most, the investment in synthetic oil will pay back over the lifetime of the vehicle.  

  • Can all vehicles take synthetic motor oil?

    All modern vehicles can take synthetic motor oil, but you can confirm in your owner’s manual to make sure. If you have a classic car or have additional questions, please reach out to Northwest Ohio’s AMSOIL Independent Dealer network, and we can help answer any questions specific to your vehicle’s make and model.  

  • Are there vehicles that only take synthetic motor oil?

    Many high-performance engines found in the marine and racing niche require the use of synthetic motor oil due to the high demands on the motor itself. Your owner’s manual will confirm what the requirements of your specific engine make or model.
