What is the minimum TBN requirement?

Read our primer articles on High Mileage Oil, Synthetic Oil and Kinematic Viscosity

Dear Friends, I wish to know what is minimum TBN to be maintained for Engine oils to meet API specifications. I get API viscosity specifications for oil. Nothing says about minimum TBN to be maintained for Engine oil. If we dose additive as per the supplier requirement, same oil will have different TBN when we use different additive supplier. Please explain.
