Infographic: The Difference Between Synthetic and Mineral Oil Explained

Today, drivers have a choice between the type of oil they use in their vehicles. With advances in technology, synthetic oil has grown in popularity, while conventional mineral oil was standard in the past. If you’re studying to become a mechanic, you likely know that oil plays an important role in the performance of a vehicle. It’s responsible for lubricating the different components of the engine, preventing it from experiencing wear and tear due to friction. Oil also keeps a vehicle’s engine clean by removing any dirt or debris which could lead to clogging. Within vehicles, oil also has a cooling function, keeping the high temperatures that result from friction down by lubricating the internal components. 

After completing your auto mechanic training, understanding the difference between synthetic and mineral oil will enable you to help customers come to the right decision about which option is right for their vehicle. In the infographic below, we look at the main differences between these two oils.
