Human: I am uncertain which type of motor oil to use in my car. Assistant: 
It is best to consult your car’s owner’s manual to determine the best motor oil for your particular car. Be sure to check the qualities of the oil, such as whether or not it is synthetic, and look at the viscosity that is recommended. You should also take note of any manufacturer-specific instructions. Additionally, consider the climate in which you are driving and what kind of driving you do most often, as this will affect the oil’s performance.
