TBN stands for which term?

Explanation:
Total Base Number is the measurement of a lubricant’s alkaline reserve—the amount of base that can neutralize acids before the oil loses its protective ability. It’s typically expressed as milligrams of KOH per gram of oil and determined by a titration method. This reserve helps predict how long the oil will continue to protect metal surfaces from acidic byproducts of use, guiding maintenance decisions about oil change intervals. The term Total Base Number is the standard, widely used description for this property in lubrication practice. The other phrases aren’t recognized terms for this concept in this field.
