When you go to the auto store to buy motor oil, do you really know what you're choosing? When a technician asks if you want synthetic or regular oil, do you understand the difference? If these situations make you feel unsure, let’s take a closer look at your options so that next time you can confidently choose the right oil for your vehicle.

What Are the Benefits of Synthetic Oil Over Conventional Oil?

Synthetic oil is generally considered superior to conventional oil. It uses a higher-quality base oil compared to the less-refined base oil found in conventional motor oils. Full synthetic oil is specifically formulated to deliver enhanced performance and protection, making it ideal for modern engines. Unlike conventional oil, which can break down quickly under extreme temperatures, synthetic oil maintains its integrity better and lasts longer.

Synthetic motor oil is chemically engineered from petrochemicals. This process removes impurities and creates molecules that are more uniform and tailored to meet the demands of today's high-performance engines. As a result, synthetic oil offers several advantages over conventional oil:

• Provides better engine wear protection
• Helps keep your engine cleaner
• Flows more efficiently in cold weather
• Offers improved protection at high temperatures
• Protects critical components like turbochargers

Synthetic oil also allows for longer oil change intervals, which can save you time and money in the long run. While it may cost twice as much as conventional oil, the benefits often justify the price. However, always check your vehicle’s manufacturer recommendations before making a choice.

In general, the advantages of synthetic oil outweigh those of conventional oil. The decision depends on your vehicle’s requirements, how frequently you drive, and how often you maintain your car. Motor oil is the most important fluid in your vehicle, as it lubricates all the moving parts of your engine. Choosing the right type is essential for maintaining your engine’s health and performance.

Understanding Conventional Oil

Conventional oil, sometimes called “old school oil,” has been used for decades to protect car engines. It’s made from refined crude oil and provides adequate protection for many types of engines. However, its molecular structure begins to break down when it reaches around 275°F. At this point, it loses its ability to lubricate, cool, and protect your engine, leading to increased friction and heat buildup.

Many non-performance and naturally aspirated engines operate below this temperature and can function well with conventional oil—provided it is changed regularly. However, not all engines are compatible with conventional oil. Some high-performance or modern engines require full synthetic oil to function properly. Here are some engines typically compatible with conventional oil:

• Older engines
• Naturally aspirated engines
• Economy engines
• Some hybrid engines

The Science Behind Synthetic Oil

While the term "synthetic oil" might suggest it's created in a lab, most synthetic oils are derived from refined crude oil or natural gas. These oils are chemically engineered to provide better protection than both conventional and blended oils. They can withstand higher temperatures—up to 500°F—and perform well in both hot and cold conditions.

Because of its advanced molecular structure, synthetic oil offers superior lubrication, cooling, and protection. It’s especially recommended for turbocharged, high-performance, and heavy-duty engines. In cold weather, synthetic oil flows more easily than conventional oil, preventing damage during cold starts.

Here are some engines that typically require synthetic oil:

• Turbocharged engines
• High-performance engines
• Engines with high compression ratios
• Most German and Swedish engines

What About the Third Type of Oil?

Many drivers don’t realize there are actually three types of motor oil available: conventional, synthetic, and synthetic blend. For older engines that were designed to use conventional oil, a synthetic blend oil change may be a good middle ground.

Synthetic blend oil combines the benefits of both conventional and synthetic oils. It contains synthetic additives that enhance protection, especially for aging engines. These blends often include detergents that help prevent carbon buildup and sludge, as well as sealants that reduce oil leaks.

Although synthetic blends aren’t always suitable for engines designed for full synthetic oil, they’re a great option for vehicles that were built to run on conventional oil. They offer better protection than conventional oil and last longer between changes.

Different Levels of Protection and Oil Change Intervals

Because conventional oil breaks down faster and offers less protection, it's usually recommended to change it every 3,000–5,000 miles. Continuing to use it beyond this interval can lead to serious engine damage. Synthetic blend oil has a longer change interval than conventional oil but not as long as full synthetic oil. It’s typically recommended to change synthetic blend oil every 5,000–7,500 miles.

Synthetic oil, on the other hand, resists oxidation and burns cleaner, allowing for longer intervals—often 7,500–10,000 miles. Engines that run on synthetic oil tend to last longer because the oil keeps the engine clean and well-lubricated over time.
