When should you get an oil change? It depends. If your vehicle manufacturer's refill standards call for synthetic oil, you may be able to go 7,500 to 15,000 miles before requiring an oil change. Why? You can thank synthetic oil for that. Here's our Dallas Collision Center team's quick lesson on synthetic oil.

Made to Last

At the molecular level synthetic oil resembles any other oil. However, there is a twist. Oil, rubber and petroleum consist of special molecules called hydrocarbons. Long and chainlike, hydrocarbon molecules give these substances their viscous, slippery qualities. It also makes these substances either gas, solid or liquid depending on the molecular structure. Hydrocarbons do not mix with water.

With synthetic oil, scientists take hydrogen and carbon atoms, put them together and build petroleum-like hydrocarbons from scratch. Each molecule has identical shape and size, resulting in a uniformly viscous, highly shelf-stable oil.

Today's Engines: Built for Synthetic Oil

Conventional oil remains an industry favorite for its compatibility with older vehicles and its easy availability. However, it's becoming increasingly common for newer vehicles to have engines designed specifically for use with synthetic oil. Owing to new engine technology and the superb way that synthetic oil lubricates, protects and cleans machine parts, engines relying on synthetic oil work more efficiently and over longer periods before requiring an oil change.
