Total Base Number (TBN) Oil Analysis | Maintain Equipment & Reduce Downtime

Diesel engine oil is continuously exposed to acidic combustion products and these must be neutralised before they can corrode engine parts. Alkaline additives are present to neutralise both the acids derived from combustion (mainly strong sulphuric and nitric acids) and those weaker, organic acids resulting from oxidation of the oil during its ageing. The TBN of an oil is the measure of the alkaline reserve rather than a measure of how alkaline an oil is, and is used to determine the ability of the oil to neutralise acids from combustion.

Maintaining the correct alkaline reserve is critical to preventing unnecessary corrosion of the upper piston, piston rings and top end bearing. Severe depletion of the Total Base Number (TBN) results in acid corrosion and fouling within the engine, and additionally, low TBN is indicative of reduced oil detergency.
