With the advancements made in automotive technology, motor oil has come a long way in terms of quality. While many drivers know that synthetic oil offers many benefits compared to conventional oil, many aren’t aware of the differences between full synthetic oil and synthetic blends. Here’s a breakdown of what you should know and how to choose the right kind of oil for your car.

What’s the Difference Between Full Synthetic Oil and Synthetic Blends?

While conventional oils are derived from refined crude oil, synthetic oils are made entirely from lab-synthesized chemical compounds. The process involves breaking down petroleum molecules and rebuilding them to create an oil that provides exceptional lubrication. Synthetic blends, however, are a mixture of both conventional and synthetic oils—typically 20-30% synthetic oil and 70-80% conventional oil. They provide some of the advantages of synthetic oils while being more budget-friendly.

Full synthetic oils excel in extreme temperatures, which makes them the ideal choice for high-performance vehicles or cars that are regularly subjected to harsh environments. They’re significantly more durable than conventional oils and synthetic blends, so they don’t need to be changed as often; the average oil change interval for most vehicles using full synthetic oil is every 5,000 to 7,500 miles—and in some cases, up to every 10,000 miles. In addition, synthetic oils contain fewer impurities, so engines that use them run cleaner and don’t experience as many deposits.

As for synthetic blends, they offer better protection and performance in extreme temperatures compared to conventional oils alone. They also tend to be more cost-effective than full synthetic oils, so they’re a popular choice for budget-conscious drivers.

Which Type of Oil Is Better?

Which type of oil is better for your car depends on your driving needs, manufacturer’s recommendations, and budget.

If you own a high-performance vehicle or performance is a priority for you, fully synthetic oil is likely the best option. However, if you’re looking for a more affordable option that still provides some of the benefits of synthetic oil, a synthetic blend is a good alternative.

It’s also important to know that not all synthetic oils are formulated the same. There are different types and combinations of base oils and additives that can have an impact on their performance. Some synthetic oils are designed to clean your engine, while others focus on providing enhanced protection against wear and tear. If you’re not sure which type of oil would be best for your vehicle and driving conditions, check the manufacturer’s recommendations in your owner’s manual, or ask your service advisor. They can help you select the most suitable oil formulation for your needs.

What to Consider When Switching to Full Synthetic Oil

In most cases, most cars can be transitioned from conventional oil or synthetic blends to full synthetic oil, but there are a few considerations:

  • Compatibility. It’s important to make sure your vehicle is compatible with synthetic oil. Most modern vehicles are designed to accommodate it, but it’s always a good idea to check your owner’s manual or ask your service advisor before making the switch.
  • Oil change intervals. Synthetic oils typically have a longer service life compared to conventional oil or synthetic blends. As a result, you’ll likely need to adjust your oil change intervals.
  • Potential leaks. Synthetic oils have different properties and consistencies than conventional oils. If your vehicle has been using conventional oil for a long time, switching to full synthetic oil may reveal existing leaks due to its ability to clean deposits and sludge that may have been keeping the system sealed. After making the switch, be sure to keep an eye out for leaks and schedule repairs promptly.
  • Cost. Full synthetic oil is generally more expensive than conventional oil or synthetic blends—but it’s well-worth the price for the additional protection it provides. Consider your budget and weigh the benefits to determine if it’s the right choice for you. 

When switching to full synthetic oil, it’s best to choose one that excels in several performance areas. For example, some oils may offer excellent protection at low temperatures but don’t perform as well on hot summer days. To ensure your engine has comprehensive protection, it’s a good idea to choose a well-rounded oil that performs consistently across different conditions.
