A synthetic blend refers to a blend of regular oil and synthetic oil. Adding regular oil to this oil will not in any way hurt your car’s engine. You won’t even have to worry about getting an oil change until it is time for your regular interval oil change. However, if you are still concerned, you can always contact a certified technician, such as one from YourMechanic, with any further questions.
