Learn more about the differences between synthetic and conventional oil below, along with the benefits of synthetic.

Synthetic vs. Conventional

First, how is synthetic different from other motor oils? Synthetic motor oil is a more modern and sophisticated formula compared to the conventional motor oils of the past. While conventional motor oil lasts around 3,000 to 5,000 miles, synthetic can last for twice as long! Synthetic oil is widely used in new Mercedes-Benz vehicles. Its longer life means you spend less time on maintenance while enjoying better performance and fuel economy. Take a look at our service specials for opportunities to save on your next oil service.

Benefits of Synthetic

Synthetic motor oil lasts far longer than its conventional counterpart, but that’s not the only benefit:

  • Synthetics were formulated to handle higher temperatures and harder work than conventional oil, so you’ll get better performance out of every Synthetic Motor Oil Replacement.
  • Synthetic oil stays cleaner for longer than conventional, which is great for both your car and the environment.
  • Synthetic oil is ideal for performance cars like the Mercedes-Benz AMG® GT, because it can handle the stress and strain of high-octane performance without missing a beat.
