When you go to purchased motor oil from your local auto store, do you know what you’re really paying for? When a service attendant asks you synthetic or regular, do you know the difference? If these situations leave you feeling unsure, let’s examine your options so next time you can make an informed decision. 

What Are the Advantages of Synthetic Oil Over Conventional Oil?

First off, synthetic oil is better than conventional oil. Synthetic motor oil uses a higher quality base oil as compared to the less-refined base oil used in conventional oils. Full synthetic oil provides better engine performance and protection than conventional motor oils and they are specially formulated to provide additional performance benefits. Conventional oil — when compared to synthetic oil — easily breaks down in extreme high temperatures and does not last long. 

Synthetic motor oils are chemically developed from petrochemicals. The process removes impurities from the crude oil and enables inpidual molecules tailored for the demands of modern engines. This provides higher levels of performance and protection than conventional oils. Synthetic motor oil outperforms conventional oil by:

  • Offering greater engine wear protection
  • Keeping your engine cleaner
  • Flowing better in low temperatures
  • Protecting the engine better at high temperatures
  • Protecting critical turbocharge parts

Synthetic oil also gives you a longer oil change interval than conventional oil. This advanced technology and highly effective oil does not come cheap.

Synthetic oil can cost twice as much as conventional oil, but it is worth the buy. Before choosing what type of oil to use, however, be sure to check your vehicle’s manufacturer recommendations. 

Overall, the advantages of synthetic motor oil far outweigh that of conventional oil. The decision comes down to manufacturer requirements, how much you drive and how diligent you are about changing your oil. Your motor oil lubricates all the moving parts of your engine, so it is the most important fluid you use in your vehicle. It is essential to choose an oil that is best for your vehicle health and needs.
