When you check your oil, you need to seriously consider changing the oil, and what kind of oil is needed. You need to know what kind, that is, whether synthetic or natural, and you need to know the numbers associated with your particular vehicle's engine.
To take the guesswork out of an oil change, it is best to follow the manufacturer's recommendation, and the warranty requirements for your vehicle.
The best place to have your oil changed is the dealer where you purchased the vehicle. They can also let you know exactly what type of oil to use, and when it should be checked and changed. The dealer's technicians are there to help. Give them a call.
