îä ÷åøä àí òåìéí îòì 10?It is generally believed that if the TBN in used or in-service oil has gone down to half (50%) or less than half of the new or fresh oil, the oil has to be changed. For example, an engine oil with a initial base number of 10mg KOH/g should be changed if the base number is less than 5mg KOH/g.
When you test an oils base number it means that you are measuring its alkaline reserve or its ability to nutralize corrozive and degradation acids. Though viscosity is one of the most important critera, base number indicates if the oil is suitable for continued use and is an important parameter for entending oil drain intervals. A decrease in base number is usually accompanied by an increase in viscosity, oxidation and nitration.
Base Number (TBN) is like a shield to the oil because :
It effectively controls the acids formed during the combustion process by nutralizing them
Suspends wear causing contaminants
Prevents breakdown of the oil film
