http://www.thefreedictionary.com/tribologistThere is no "perfect" motor oil. It is, like most things in life, the best "compromise" of ingredients to meet a certain goal or situation.
Pick what is the most important attributes you require and blend the oil accordingly

Like my tire engineer friend says about tires:
1)Long wearing
2)Good traction
3)Low cost
pick any two you want, I can't give you all three
