Can Synthetic Motor Oil be Mixed With Regular?
It is generally safe to mix synthetic motor oil with regular motor oil in emergency situations, as long as the oils meet the same viscosity and performance requirements. Mixing different oils may dilute the performance of the oils, so it is important to make sure that the resulting mixture meets the specific needs of your vehicle. We don’t recommend mixing synthetic motor oil with regular motor oil as this will void AMSOIL’s Warranty, but in emergency situations it’s better to have oil than no or low oil, just make sure you have the oil changed sooner if you had to mix synthetic and regular.
For example, if you are using a synthetic motor oil with a higher viscosity than the conventional motor oil you are mixing it with, the resulting mixture may not provide the desired level of protection for your engine. Similarly, if you are mixing a synthetic motor oil with a lower viscosity than the conventional motor oil, the resulting mixture may not provide sufficient lubrication for your engine.
It is also important to keep in mind that mixing synthetic and conventional motor oils can shorten the oil change interval, as the mixture may not be able to maintain its performance for as long as pure synthetic motor oil. This may result in the need for more frequent oil changes, which can be inconvenient and costly.
In summary, it is generally safe to mix synthetic and conventional motor oils, as long as the resulting mixture meets the specific needs of your vehicle and the oils are compatible. However, mixing different oils can dilute their performance and may require more frequent oil changes. It is important to consult your vehicle’s owner’s manual and follow the manufacturer’s recommendations for the type of oil to use.
