Good oil allows your engine to operate at its peak. However, you need to make sure that you have the right information about your oil. You have probably been told that you need a thicker oil for protection, but that is a myth. In fact, if you use an oil that is too thick you will actually decrease the efficiency of your engine.
Synthetic oil is the standard oil that is used today. It has been around since the 70s, but the same myths about still persist. Many people believe that using synthetic oil can cause the engine to leak. However, there is no truth to that.
Additionally, despite what you may have heard, you may not need to change your oil if it is black. Oil has a tendency to darken over time due to oxidation. You should consult with the owner’s manual in order to find out when you need to get the oil changed.
