Construction Engine Fluid Analysis

Engine oil testing is a key component of a Predictive Maintenance Program (PMP) for heavy construction equipment owners. Engine oil testing can be scheduled based on test data trends of the equipment. Depending on the test data it is possible to extend the time between engine oil changes which can help to save money and schedule equipment utilization. 

A vital test for construction equipment is the Total Base Number or TBN that measures acidity or acid build up in the engine oil. When crankcase oils are exposed to acidic compounds, it is key to monitor TBN to ensure the oil has sufficient alkaline properties thereby reducing the corrosive effects of acidity in the oil. The TBN is tested in accordance with ASTM D2896 or IP400.  

Other important tests to consider for engine oil testing includes contaminants such as dust, glycol or antifreeze in the engine block. The introduction of these impurities into the engine crankcase will cause corrosion, clogging and accelerated wear of the engine. Clark Lab’s Engine Test Package (ETP) will analyze the health of the engine oil and help identify typical contaminants of impediments to the reliability of the engine.
