In a luxury brand vehicle, such as your Audi model, you'll want to know the difference between oil and high-quality oil. It is imperative that you keep your engine filled with the best oil on the market to keep it as pristine as it should be.
Both conventional and synthetic oils start out in the ground, but they couldn't be more different. Conventional oil is refined, but nothing else is added to it. Synthetic oil is also refined, but is then distilled, purified, and broken down to make it perfect for modern engines and high-quality powertrains; like that in your Audi car or SUV.
