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

Along with knowing how often to change your oil, it is important that you use the right type of motor oil – synthetic oil vs. conventional oil – for your vehicle. In this guide from the service experts at Cadillac South San Francisco, we will compare synthetic oil vs. conventional oil and full synthetic oil vs. synthetic blends so you can see which will best keep your Cadillac car, crossover, or SUV always running at peak performance levels on San Francisco-area roads.

What is Conventional (Regular) Oil?

Conventional oil, or “regular” oil, is distilled from crude oil and provides lubrication to reduce engine wear. It also serves to protect your car’s engine from high temperatures, and as long as you keep up to date with your oil change schedule, it can improve fuel efficiency on your Oakland commute.

What is Synthetic Oil?

Synthetic oil is also refined from crude oil, but it provides enhanced lubrication properties and is more stable. Synthetic oils are manufactured to oxidize less easily than conventional oils and are also better at protecting internal engine components. However, due to their more intensive refining process, they tend to cost more than conventional oils. Synthetic oil offers benefits such as:

  • Less viscosity at lower temperatures
  • Improved engine cleaning properties
  • More protection to critical turbocharger parts (if so equipped)

Full Synthetic Oil vs. Synthetic Blends

Along with knowing the difference between synthetic oil vs. conventional oil, you may also want to find out about full synthetic oil vs. synthetic blends. A synthetic blend is just what it sounds like; a blend of synthetic and conventional oil. Some San Mateo drivers opt for a synthetic blend since it can provide many of the benefits of synthetic oil at a more affordable price.

Note that certain vehicles require full synthetic oil. It’s a good idea to check your owner’s manual or contact our Service Center if you have any questions about what kind of oil your car requires.
