Synthetic Oil vs. Regular Oil: What’s the Difference?

Mechanic performing oil change

Any new or used vehicle with an internal combustion engine will need oil changes regularly. Depending on the make, model, and year, your oil change interval might be every 3,000 miles or even up to 10,000 miles near Federal Way. It also depends on whether you use synthetic oil vs. regular oil because one requires a shorter oil change interval than the other. Which type of oil should you use in your car? Find out everything you need to know about the differences between synthetic oil vs. regular oil in this handy guide from the Sunset Kia of Auburn service team!



Synthetic Oil vs. Regular Oil: What Is Regular Oil?

Regular oil, otherwise known as conventional oil, starts are crude petroleum beneath the surface of the earth. It’s extracted and then shipped to refineries in 55-gallon drums. At the refinery, chemical engineers apply complex chemical processes to turn crude petroleum into the amber-colored motor oil that works in your vehicle’s engine. Regular oil lubricates the pistons in your engine to keep them from overheating due to friction as your car moves forward. 

Synthetic Oil vs. Regular Oil: What Is Full Synthetic Oil?

Full synthetic oil comes from the same processes as regular oil with one distinct difference. Full synthetic oil undergoes even more refinement, and it contains more stabilizers, anti-oxidizers, and anti-gumming agents to keep the oil fresher for longer periods. The lone downside to full synthetic oil is the upfront cost. But, you’ll save money over the long term because you have fewer oil changes and your engine will last longer. Full synthetic oils also:

  • Are less viscous at lower temperatures
  • Offer improved cleaning agents to prevent build-up in the engine
  • Better protect critical turbocharger parts (when equipped)

Full Synthetic Oil vs. Synthetic Blend

Synthetic and conventional oil aren’t your only choices on the oil market– synthetic blends are also available! Synthetic blends reduce your upfront costs when choosing full synthetic oil vs. synthetic blends. Synthetic blends won’t perform as well, yet they are better than regular oil.

When comparing full synthetic oil vs. synthetic blends, you’ll get some of the benefits of synthetic oil. 

Pro Tip: Some manufacturers of high-performance or new vehicles require full synthetic oil for their engines. Look over your owner’s manual or contact our service center near Sumner to find out what oil your engine needs.
