When you go to buy motor oil, do you really know what you're getting? When a mechanic asks if you want synthetic or conventional, do you understand the difference? If these questions make you feel unsure, this guide will help you make an informed decision next time you get your oil changed.

What Are the Benefits of Synthetic Oil Over Conventional Oil?

Synthetic oil is generally superior to conventional oil. It starts with a higher quality base oil that's more refined than the crude oil used in conventional options. Full synthetic oil is specially designed to offer better performance and protection for modern engines. Unlike conventional oil, which can break down quickly under extreme heat, synthetic oil maintains its integrity and lasts longer.

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

• Offers better engine wear protection
• Helps keep your engine cleaner
• Flows more easily in cold temperatures
• Provides better protection at high temperatures
• Protects turbocharged components

Synthetic oil also allows for longer oil change intervals. While it may cost more upfront, the long-term benefits often justify the investment. However, always check your vehicle’s manufacturer recommendations before making a choice.

In general, synthetic oil offers significant advantages over conventional oil. The right choice depends on your car’s requirements, how often you drive, and how regularly you maintain your vehicle. Since motor oil is essential for lubricating your engine’s moving parts, choosing the best one for your needs is crucial for your car’s health.

Understanding Conventional Oil

Conventional oil, sometimes called "old school oil," has been used for decades to protect engines. It's made from refined crude oil and provides adequate protection for many vehicles. However, it begins to oxidize at around 275°F, losing its ability to lubricate, cool, and protect your engine effectively.

Many non-performance and naturally aspirated engines can still run well on conventional oil, especially if you follow the recommended oil change intervals. But not all engines are compatible with conventional oil. Some high-performance or turbocharged engines may require synthetic oil to avoid damage.

Here are the types of engines typically compatible with conventional oil:

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

The Science Behind Synthetic Oil

While synthetic oil might sound like it's made in a lab, most of it is actually derived from refined crude oil or natural gas. It’s then chemically modified to provide better performance and protection. Synthetic oil can withstand higher temperatures—up to 500°F—and performs well in both hot and cold conditions.

Because of its molecular structure, synthetic oil offers better lubrication, cooling, and protection than conventional oil. It’s especially recommended for turbocharged, high-performance, and heavy-duty engines that operate under stress.

A synthetic oil change helps protect engines in cold weather by maintaining its flowability even when temperatures drop below freezing. Conventional oil can thicken and fail to circulate properly, leading to potential engine damage during cold starts.

Here are the types of engines that usually 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?

Did you know there are actually three types of motor oil available? For high-mileage engines that were designed for conventional oil, a synthetic blend can be a great option. It combines the benefits of both conventional and synthetic oils.

Synthetic blend oil uses a conventional base with added synthetic additives for enhanced protection. It includes detergents to reduce carbon buildup and sludge, and sealants to prevent leaks. These features make it ideal for older engines that need extra care.

Although synthetic blends aren’t always suitable for engines that require full synthetic oil, they’re a good middle ground for aging vehicles that benefit from improved performance and longevity.

Different Levels of Protection and Change Intervals

Conventional oil breaks down faster and requires more frequent changes—typically every 3,000 to 5,000 miles. Using it beyond this interval can lead to serious engine damage.

Synthetic blend oil lasts longer than conventional but not as long as full synthetic. It’s recommended to change it every 5,000 to 7,500 miles.

Synthetic oil resists oxidation and burns cleaner, allowing for longer intervals—usually every 7,500 to 10,000 miles. Engines that use synthetic oil tend to last longer due to the reduced buildup of sludge and deposits.
