Abstract:
This study was designed to quantify the effect of engine oil on water separability of Industrial oil (Gear 320) and Hydraulic oil (EP 150). An engine oil (CF50) was added as a contaminant for the two blends samples. Water separability was determined for contaminated lubricating oils. Industrial oil (Gear 320) showed a significant drop on the water separability at low concentration of calcium (0.0004%), but the hydraulic oil (EP 150) showed the same effect in high concentration of calcium (0.014%) compared to industrial oil (Gear 320). The study concluded that contamination with engine oil has a negative impact on the water separability of Industrial oil (Gear 320) and a Hydraulic oil (EP150), also an Industrial oil is extremely sensitive to contamination with engine oil than the hydraulic oil.
