What fuel oil test provides an indication of fuel oil contamination?

Contamination in fuel oil is typically water and solids that settle out. The test that shows this directly is the Bottom Sediment and Water (BS&W) test. It measures how much water and sediment are present in a fuel sample, usually by allowing separation or using a centrifuge and then quantifying the collected water and solids. A higher BS&W value signals more contamination, prompting actions like filtration, treatment, or replacement. The other tests assess different properties: API gravity gauges density, viscosity measures flow resistance, and cloud point looks at wax crystallization at low temperatures. These reveal quality and performance aspects but don’t directly indicate contamination in the fuel.
