If you’ve never owned a German car before, you might not be familiar with this strange rule regarding regular and synthetic oil in your engine. There are quite a few reasons that you cannot use regular oil in an Audi or BMW, one of the most important being that you will void the warranty of the vehicle if you do so.
Synthetic Oil Flows Better Through Your Engine
This rule was set in place in order to enforce the use of synthetic oil, and there’s good reason too. Conventional oil and synthetic oil have different weights and densities to them, which changes how the oil flows through the engine. The thicker viscosity of natural oil doesn’t flow properly, which causes the engine to wear out faster.
Synthetic Oil is Cleaner Than Regular Oil
While commonly used natural motor oil is refined from crude oil, it can still contain unwanted elements that make it through this process. These small minerals can gradually cause unwanted buildup in an engine which can hurt the performance and the lifespan of the engine. Alternatively, synthetic oil doesn’t have this issue because it’s synthesized with chemical compounds in a controlled process, which eliminates the possibility of contamination.
Synthetic Oil Performs Better in Extreme Temperatures
In addition to being cleaner and lower viscosity, synthetic oil is also designed to better regulate the temperature of your engine. Not only does it perform better in extreme heat and extreme cold, but it keeps your engine from overheating and prevents unnecessary wear and tear. This not only improves performance but increases the lifespan of your engine.
Synthetic Oil Provides More Mileage Per Change
Although Synthetic oil is more expensive than natural options, it is designed to be changed less often, therefore giving you more miles in between each oil change. While this factor probably won’t save you money it will gradually even out to be about the same cost as regular oil. In other words, don’t sweat spending a little more for an oil change, it will save you trouble in the long run.
Have Your Vehicle Serviced by An Expert
BMW and Audi each have very similar lists of oil brands and types that are safe to use in their vehicles. Depending on what year your vehicle was made, and even what climates you’re driving in, the type of oil that is most efficient could be different.
